If you think you may have found a bug in GCC, please
read the Bugs section of the GCC manual for advice on
(1) how to tell when to report a bug,
(2) where to send your bug report, and
(3) how to write a useful bug report and what information
it needs to have.
There are three ways to read the Bugs section.
(1) In a printed copy of the GCC manual. You can order one from the
Free Software Foundation; see the file ORDERS. But if you don't have
a copy on hand and you think you have found a bug, you shouldn't wait
to get a printed manual; you should read the section right away as
described below.
(2) With Info. Start Emacs, do C-h i to enter Info,
then m gcc RET to get to the GCC manual, then m Bugs RET
to get to the section on bugs. Or use standalone Info in
a like manner. (Standalone Info is part of the Texinfo distribution.)
(3) By hand. Search for the chapter "Reporting Bugs" in gcc.texi, or
cat /usr/local/info/gcc* | more "+/^File: gcc.info, Node: Bugs,"
You may also want to take a look at the GCC FAQ, in which there are
additional instructions for submitting bug reports:

3. When find_reloads is used to count number of spills needed
it does not take into account the fact that a reload may
turn out to be a dummy.
I'm not sure this really happens any more. Doesn't it find
all the dummies on both passes?
10. movl a3@,a0
movl a3@(16),a1
clrb a0@(a1:l)
is generated and may be worse than
movl a3@,a0
addl a3@(16),a0
clrb a0@
If ordering of operands is improved, many more
such cases will be generated from typical array accesses.
38. Hack expand_mult so that if there is no same-modes multiply
it will use a widening multiply and then truncate rather than
calling the library.
39. Hack expanding of division to notice cases for
long -> short division.
40. Represent divide insns as (DIV:SI ...) followed by
a separate lowpart extract. Represent remainder insns as DIV:SI
followed by a separate highpart extract. Then cse can work on
the DIV:SI part. Problem is, this may not be desirable on machines
where computing the quotient alone does not necessarily give
a remainder--such as the 68020 for long operands.
52. Reloading can look at how reload_contents got set up.
If it was copied from a register, just reload from that register.
Otherwise, perhaps can change the previous insn to move the
data via the reload reg, thus avoiding one memory ref.
63. Potential problem in cc_status.value2, if it ever activates itself
after a two-address subtraction (which currently cannot happen).
It is supposed to compare the current value of the destination
but eliminating it would use the results of the subtraction, equivalent
to comparing the previous value of the destination.
65. Should loops that neither start nor end with a break
be rearranged to end with the last break?
69. Define the floating point converting arithmetic instructions
for the 68881.
74. Combine loop opt with cse opt in one pass. Do cse on each loop,
then loop opt on that loop, and go from innermost loops outward.
Make loop invariants available for cse at end of loop.
85. pea can force a value to be reloaded into an areg
which can make it worse than separate adding and pushing.
This can only happen for adding something within addql range
and it only loses if the qty becomes dead at that point
so it can be added to with no copying.
93. If a pseudo doesn't get a hard reg everywhere,
can it get one during a loop?
96. Can do SImode bitfield insns without reloading, but must
alter the operands in special ways.
99. final could check loop-entry branches to see if they
screw up deletion of a test instruction. If they do,
can put another test instruction before the branch and
make it conditional and redirect it.
106. Aliasing may be impossible if data types of refs differ
and data type of containing objects also differ.
(But check this wrt unions.)
108. Can speed up flow analysis by making a table saying which
register is set and which registers are used by each instruction that
only sets one register and only uses two. This way avoid the tree
walk for such instructions (most instructions).
109. It is desirable to avoid converting INDEX to SImode if a
narrower mode suffices, as HImode does on the 68000.
How can this be done?
110. Possible special combination pattern:
If the two operands to a comparison die there and both come from insns
that are identical except for replacing one operand with the other,
throw away those insns. Ok if insns being discarded are known 1 to 1.
An andl #1 after a seq is 1 to 1, but how should compiler know that?
112. Can convert float to unsigned int by subtracting a constant,
converting to signed int, and changing the sign bit.
117. Any number of slow zero-extensions in one loop, that have
their clr insns moved out of the loop, can share one register
if their original life spans are disjoint.
But it may be hard to be sure of this since
the life span data that regscan produces may be hard to interpret
validly or may be incorrect after cse.
118. In cse, when a bfext insn refers to a register, if the field
corresponds to a halfword or a byte and the register is equivalent
to a memory location, it would be possible to detect this and
replace it with a simple memory reference.
121. Insns that store two values cannot be moved out of loops.
The code in scan_loop doesn't even try to deal with them.
122. When insn-output.c turns a bit-test into a sign-test,
it should see whether the cc is already set up with that sign.
123. When a conditional expression is used as a function arg, it would
be faster (and in some cases shorter) to push each alternative rather
than compute in a register and push that. This would require
being able to specify "push this" as a target for expand_expr.
124. On the 386, bad code results from foo (bar ()) when bar
returns a double, because the pseudo used fails to get preferenced
into an fp reg because of the distinction between regs 8 and 9.

C++ template friend functions (mmitchell@usa.net)
Haifa scheduler (haifa-sched.c, loop.[ch], unroll.[ch], genattrtab.c):
(contact law@cygnus.com before starting any serious haifa work)
* Fix all the formatting problems. Simple, mindless work.
* Fix/add comments throughout the code. Many of the comments are from
the old scheduler and are out of date and misleading. Many new hunks
of code don't have sufficient comments and documentation. Those which
do have comments need to be rewritten to use complete sentences and
proper formatting.
* Someone needs make one (or more) passes over the scheduler as a whole to
just clean it up. Try to move the machine dependent bits into the target
files where they belong, avoid re-creating functions where or near
equivalents already exist (ie is_conditional_branch and friends), etc., etc.
* Document the new scheduling options. Remove those options which are
not really useful (like reverse scheduling for example). In general
the haifa scheduler adds _way_ too many options. I'm definitely of the
opinion that gcc already has too many -foptions, and haifa doesn't help
that situation.
* Testing and benchmarking. We've converted a few ports to using the
Haifa scheduler (hppa, sparc, ppc, alpha). We need to continue testing
and benchmarking the new scheduler on additional targets.
We need to have some kind of docs for how to best describe a machine to
the haifa scheduler to get good performance. Some existing ports have
been tuned to deal with the old scheduler -- they may need to be tuned
to generate good schedules with haifa.
Improvements to global cse and partial redundancy elimination:
The current implementation of global cse uses partial redundancy elimination
as described in Chow's thesis.
Long term we want to use lazy code motion as the basis for partial redundancy
elimination. lcm will find as many (or more) redunancies *and* it will
place the remaining computations at computationally optimal placement points
within the function. This reduces the number of redundant operations performed
as well as reducing register lifetimes. My experiments have shown that the
cases were the current PRE code hurts performance are greatly helped by using
lazy code motion.
lcm also provides the underlying framework for several additional optimizations
such as shrink wrapping, spill code motion, dead store elimination, and generic
load/store motion (all the other examples are subcases of load/store motion).
It can probably also be used to improve the reg-stack pass of the compiler.
Contact law@cygnus.com if you're interested in working on lazy code motion.

1. Better optimization.
* Constants in unused inline functions
It would be nice to delay output of string constants so that string
constants mentioned in unused inline functions are never generated.
Perhaps this would also take care of string constants in dead code.
The difficulty is in finding a clean way for the RTL which refers
to the constant (currently, only by an assembler symbol name)
to point to the constant and cause it to be output.
* Optimize a sequence of if statements whose conditions are exclusive.
It is possible to optimize
if (x == 1) ...;
if (x == 2) ...;
if (x == 3) ...;
into
if (x == 1) ...;
else if (x == 2) ...;
else if (x == 3) ...;
provided that x is not altered by the contents of the if statements.
It's not certain whether this is worth doing. Perhaps programmers
nearly always write the else's themselves, leaving few opportunities
to improve anything.
* Un-cse.
Perhaps we should have an un-cse step right after cse, which tries to
replace a reg with its value if the value can be substituted for the
reg everywhere, if that looks like an improvement. Which is if the
reg is used only a few times. Use rtx_cost to determine if the
change is really an improvement.
* Clean up how cse works.
The scheme is that each value has just one hash entry. The
first_same_value and next_same_value chains are no longer needed.
For arithmetic, each hash table elt has the following slots:
* Operation. This is an rtx code.
* Mode.
* Operands 0, 1 and 2. These point to other hash table elements.
So, if we want to enter (PLUS:SI (REG:SI 30) (CONST_INT 104)), we
first enter (CONST_INT 104) and find the entry that (REG:SI 30) now
points to. Then we put these elts into operands 0 and 1 of a new elt.
We put PLUS and SI into the new elt.
Registers and mem refs would never be entered into the table as such.
However, the values they contain would be entered. There would be a
table indexed by regno which points at the hash entry for the value in
that reg.
The hash entry index now plays the role of a qty number.
We still need qty_first_reg, reg_next_eqv, etc. to record which regs
share a particular qty.
When a reg is used whose contents are unknown, we need to create a
hash table entry whose contents say "unknown", as a place holder for
whatever the reg contains. If that reg is added to something, then
the hash entry for the sum will refer to the "unknown" entry. Use
UNKNOWN for the rtx code in this entry. This replaces make_new_qty.
For a constant, a unique hash entry would be made based on the
value of the constant.
What about MEM? Each time a memory address is referenced, we need a
qty (a hash table elt) to represent what is in it. (Just as for a
register.) If this isn't known, create one, just as for a reg whose
contents are unknown.
We need a way to find all mem refs that still contain a certain value.
Do this with a chain of hash elts (for memory addresses) that point to
locations that hold the value. The hash elt for the value itself should
point to the start of the chain. It would be good for the hash elt
for an address to point to the hash elt for the contents of that address
(but this ptr can be null if the contents have never been entered).
With this data structure, nothing need ever be invalidated except
the lists of which regs or mems hold a particular value. It is easy
to see if there is a reg or mem that is equiv to a particular value.
If the value is constant, it is always explicitly constant.
* Support more general tail-recursion among different functions.
This might be possible under certain circumstances, such as when
the argument lists of the functions have the same lengths.
Perhaps it could be done with a special declaration.
You would need to verify in the calling function that it does not
use the addresses of any local variables and does not use setjmp.
* Put short statics vars at low addresses and use short addressing mode?
Useful on the 68000/68020 and perhaps on the 32000 series,
provided one has a linker that works with the feature.
This is said to make a 15% speedup on the 68000.
* Keep global variables in registers.
Here is a scheme for doing this. A global variable, or a local variable
whose address is taken, can be kept in a register for an entire function
if it does not use non-constant memory addresses and (for globals only)
does not call other functions. If the entire function does not meet
this criterion, a loop may.
The VAR_DECL for such a variable would have to have two RTL expressions:
the true home in memory, and the pseudo-register used temporarily.
It is necessary to emit insns to copy the memory location into the
pseudo-register at the beginning of the function or loop, and perhaps
back out at the end. These insns should have REG_EQUIV notes so that,
if the pseudo-register does not get a hard register, it is spilled into
the memory location which exists in any case.
The easiest way to set up these insns is to modify the routine
put_var_into_stack so that it does not apply to the entire function
(sparing any loops which contain nothing dangerous) and to call it at
the end of the function regardless of where in the function the
address of a local variable is taken. It would be called
unconditionally at the end of the function for all relevant global
variables.
For debugger output, the thing to do is to invent a new binding level
around the appropriate loop and define the variable name as a register
variable with that scope.
* Live-range splitting.
Currently a variable is allocated a hard register either for the full
extent of its use or not at all. Sometimes it would be good to
allocate a variable a hard register for just part of a function; for
example, through a particular loop where the variable is mostly used,
or outside of a particular loop where the variable is not used. (The
latter is nice because it might let the variable be in a register most
of the time even though the loop needs all the registers.)
Contact meissner@cygnus.com before starting any work on live range
splitting.
* Detect dead stores into memory?
A store into memory is dead if it is followed by another store into
the same location; and, in between, there is no reference to anything
that might be that location (including no reference to a variable
address).
This can be modeled as a partial redundancy elimination/lazy code motion
problem. Contact law@cygnus.com before working on dead store elimination
optimizations.
* Loop optimization.
Strength reduction and iteration variable elimination could be
smarter. They should know how to decide which iteration variables are
not worth making explicit because they can be computed as part of an
address calculation. Based on this information, they should decide
when it is desirable to eliminate one iteration variable and create
another in its place.
It should be possible to compute what the value of an iteration
variable will be at the end of the loop, and eliminate the variable
within the loop by computing that value at the loop end.
When a loop has a simple increment that adds 1,
instead of jumping in after the increment,
decrement the loop count and jump to the increment.
This allows aob insns to be used.
* Using constraints on values.
Many operations could be simplified based on knowledge of the
minimum and maximum possible values of a register at any particular time.
These limits could come from the data types in the tree, via rtl generation,
or they can be deduced from operations that are performed. For example,
the result of an `and' operation one of whose operands is 7 must be in
the range 0 to 7. Compare instructions also tell something about the
possible values of the operand, in the code beyond the test.
Value constraints can be used to determine the results of a further
comparison. They can also indicate that certain `and' operations are
redundant. Constraints might permit a decrement and branch
instruction that checks zeroness to be used when the user has
specified to exit if negative.
* Smarter reload pass.
The reload pass as currently written can reload values only into registers
that are reserved for reloading. This means that in order to use a
register for reloading it must spill everything out of that register.
It would be straightforward, though complicated, for reload1.c to keep
track, during its scan, of which hard registers were available at each
point in the function, and use for reloading even registers that were
free only at the point they were needed. This would avoid much spilling
and make better code.
* Change the type of a variable.
Sometimes a variable is declared as `int', it is assigned only once
from a value of type `char', and then it is used only by comparison
against constants. On many machines, better code would result if
the variable had type `char'. If the compiler could detect this
case, it could change the declaration of the variable and change
all the places that use it.
* Better handling for very sparse switches.
There may be cases where it would be better to compile a switch
statement to use a fixed hash table rather than the current
combination of jump tables and binary search.
* Order of subexpressions.
It might be possible to make better code by paying attention
to the order in which to generate code for subexpressions of an expression.
* More code motion.
Consider hoisting common code up past conditional branches or tablejumps.
Contact law@cygnus.com before working on code hoisting.
* Trace scheduling.
This technique is said to be able to figure out which way a jump
will usually go, and rearrange the code to make that path the
faster one.
* Distributive law.
The C expression *(X + 4 * (Y + C)) compiles better on certain
machines if rewritten as *(X + 4*C + 4*Y) because of known addressing
modes. It may be tricky to determine when, and for which machines, to
use each alternative.
Some work has been done on this, in combine.c.
* Can optimize by changing if (x) y; else z; into z; if (x) y;
if z and x do not interfere and z has no effects not undone by y.
This is desirable if z is faster than jumping.
* For a two-insn loop on the 68020, such as
foo: movb a2@+,a3@+
jne foo
it is better to insert dbeq d0,foo before the jne.
d0 can be a junk register. The challenge is to fit this into
a portable framework: when can you detect this situation and
still be able to allocate a junk register?
2. Simpler porting.
Right now, describing the target machine's instructions is done
cleanly, but describing its addressing mode is done with several
ad-hoc macro definitions. Porting would be much easier if there were
an RTL description for addressing modes like that for instructions.
Tools analogous to genflags and genrecog would generate macros from
this description.
There would be one pattern in the address-description file for each
kind of addressing, and this pattern would have:
* the RTL expression for the address
* C code to verify its validity (since that may depend on
the exact data).
* C code to print the address in assembler language.
* C code to convert the address into a valid one, if it is not valid.
(This would replace LEGITIMIZE_ADDRESS).
* Register constraints for all indeterminates that appear
in the RTL expression.
3. Other languages.
Front ends for Pascal, Fortran, Algol, Cobol, Modula-2 and Ada are
desirable.
Pascal, Modula-2 and Ada require the implementation of functions
within functions. Some of the mechanisms for this already exist.
4. More extensions.
* Generated unique labels. Have some way of generating distinct labels
for use in extended asm statements. I don't know what a good syntax would
be.
* A way of defining a structure containing a union, in which the choice of
union alternative is controlled by a previous structure component.
Here is a possible syntax for this.
struct foo {
enum { INT, DOUBLE } code;
auto union { case INT: int i; case DOUBLE: double d;} value : code;
};
* Allow constructor expressions as lvalues, like this:
(struct foo) {a, b, c} = foo();
This would call foo, which returns a structure, and then store the
several components of the structure into the variables a, b, and c.
5. Generalize the machine model.
* Some new compiler features may be needed to do a good job on machines
where static data needs to be addressed using base registers.
* Some machines have two stacks in different areas of memory, one used
for scalars and another for large objects. The compiler does not
now have a way to understand this.
6. Useful warnings.
* Warn about statements that are undefined because the order of
evaluation of increment operators makes a big difference. Here is an
example:
*foo++ = hack (*foo);
7. Better documentation of how GCC works and how to port it.

The purpose of GCC pretesting is to verify that the new GCC
distribution, about to be released, works properly on your system *with
no change whatever*, when installed following the precise
recommendations that come with the distribution.
Here are some guidelines on how to do pretesting so as to make it
helpful. All of them follow from common sense together with the
nature of the purpose and the situation.
* It is absolutely vital that you mention even the smallest change or
departure from the standard sources and installation procedure.
Otherwise, you are not testing the same program that I wrote. Testing
a different program is usually of no use whatever. It can even cause
trouble if you fail to tell me that you tested some other program
instead of what I know as GCC. I might think that GCC works, when in
fact it has not been properly tried, and might have a glaring fault.
* Even changing the compilation options counts as a change in the
program. The GCC sources specify which compilation options to use.
Some of them are specified in makefiles, and some in machine-specific
configuration files.
You have ways to override this--but if you do, then you are not
testing what ordinary users will do. Therefore, when pretesting, it
is vital to test with the default compilation options.
(It is okay to test with nonstandard options as well as testing with
the standard ones.)
* The machine and system configuration files of GCC are parts of
GCC. So when you test GCC, you need to do it with the
configuration files that come with GCC.
If GCC does not come with configuration files for a certain machine,
and you test it with configuration files that don't come with GCC,
this is effectively changing GCC. Because the crucial fact about
the planned release is that, without changes, it doesn't work on that
machine.
To make GCC work on that machine, I would need to install new
configuration files. That is not out of the question, since it is
safe--it certainly won't break any other machines that already work.
But you will have to rush me the legal papers to give the FSF
permission to use a large piece of text.
* Look for recommendations for your system.
You can find these recommendations in the Installation node of the
manual, and in the file INSTALL. (These two files have the same text.)
These files say which configuration name to use for your machine, so
use the ones that are recommended. If you guess, you might guess
wrong and encounter spurious difficulties. What's more, if you don't
follow the recommendations then you aren't helping to test that its
recommendations are valid.
These files may describe other things that you need to do to make GCC
work on your machine. If so, you should follow these recommendations
also, for the same reason.
Also look at the Trouble chapter of the manual for items that
pertain to your machine.
* Don't delay sending information.
When you find a problem, please double check it if you can do so
quickly. But don't spend a long time double-checking. A good rule is
always to tell me about every problem on the same day you encounter
it, even if that means you can't find a solution before you report the
problem.
I'd much rather hear about a problem today and a solution tomorrow
than get both of them tomorrow at the same time.
* Make each bug report self-contained.
If you refer back to another message, whether from you or from someone
else, then it will be necessary for anyone who wants to investigate
the bug to find the other message. This may be difficult, it is
probably time-consuming.
To help me save time, simply copy the relevant parts of any previous
messages into your own bug report.
In particular, if I ask you for more information because a bug report
was incomplete, it is best to send me the *entire* collection of
relevant information, all together. If you send just the additional
information, that makes me do extra work. There is even a risk that
I won't remember what question you are sending me the answer to.
* Always be precise when talking about changes you have made. Show
things rather than describing them. Use exact filenames (relative to
the main directory of the distribution), not partial ones. For
example, say "I changed Makefile" rather than "I changed the
makefile". Instead of saying "I defined the MUMBLE macro", send a
diff that shows your change.
* Always use `diff -c' to make diffs. If you don't include context,
it may be hard for me to figure out where you propose to make the
changes. I might have to ignore your patch because I can't tell what
it means.
* When you write a fix, keep in mind that I can't install a change
that would break other systems.
People often suggest fixing a problem by changing machine-independent
files such as toplev.c to do something special that a particular
system needs. Sometimes it is totally obvious that such changes would
break GCC for almost all users. I can't possibly make a change like
that. All I can do is send it back to you and ask you to find a fix
that is safe to install.
Sometimes people send fixes that *might* be an improvement in
general--but it is hard to be sure of this. I can install such
changes some of the time, but not during pretest, when I am trying to
get a new version to work reliably as quickly as possible.
The safest changes for me to install are changes to the configuration
files for a particular machine. At least I know those can't create
bugs on other machines.
* Don't try changing GCC unless it fails to work if you don't change it.
* Don't even suggest changes that would only make GCC cleaner.
Every change I install could introduce a bug, so I won't install
a change unless I see it is necessary.
* If you would like to suggest changes for purposes other than fixing
serious bugs, don't wait till pretest time. Instead, send them just
after I make a release. That's the best time for me to install them.
* In some cases, if you don't follow these guidelines, your
information might still be useful, but I might have to do more work to
make use of it. Unfortunately, I am so far behind in my work that I
just can't get the job done unless you help me to do it efficiently.
Thank you

Notes on the GNU Implementation of DWARF Debugging Information
--------------------------------------------------------------
Last Updated: Sun Jul 17 08:17:42 PDT 1994 by rfg@segfault.us.com
------------------------------------------------------------
This file describes special and unique aspects of the GNU implementation
of the DWARF debugging information language, as provided in the GNU version
2.x compiler(s).
For general information about the DWARF debugging information language,
you should obtain the DWARF version 1 specification document (and perhaps
also the DWARF version 2 draft specification document) developed by the
UNIX International Programming Languages Special Interest Group. A copy
of the DWARF version 1 specification (in PostScript form) may be
obtained either from me <rfg@netcom.com> or from the main Data General
FTP server. (See below.) The file you are looking at now only describes
known deviations from the DWARF version 1 specification, together with
those things which are allowed by the DWARF version 1 specification but
which are known to cause interoperability problems (e.g. with SVR4 SDB).
To obtain a copy of the DWARF Version 1 and/or DWARF Version 2 specification
from Data General's FTP server, use the following procedure:
---------------------------------------------------------------------------
ftp to machine: "dg-rtp.dg.com" (128.222.1.2).
Log in as "ftp".
cd to "plsig"
get any of the following file you are interested in:
dwarf.1.0.3.ps
dwarf.2.0.0.index.ps
dwarf.2.0.0.ps
---------------------------------------------------------------------------
The generation of DWARF debugging information by the GNU version 2.x C
compiler has now been tested rather extensively for m88k, i386, i860, and
Sparc targets. The DWARF output of the GNU C compiler appears to inter-
operate well with the standard SVR4 SDB debugger on these kinds of target
systems (but of course, there are no guarantees).
DWARF generation for the GNU g++ compiler is still not operable. This is
due primarily to the many remaining cases where the g++ front end does not
conform to the conventions used in the GNU C front end for representing
various kinds of declarations in the TREE data structure. It is not clear
at this time how these problems will be addressed.
Future plans for the dwarfout.c module of the GNU compiler(s) includes the
addition of full support for GNU FORTRAN. (This should, in theory, be a
lot simpler to add than adding support for g++... but we'll see.)
Many features of the DWARF version 2 specification have been adapted to
(and used in) the GNU implementation of DWARF (version 1). In most of
these cases, a DWARF version 2 approach is used in place of (or in addition
to) DWARF version 1 stuff simply because it is apparent that DWARF version
1 is not sufficiently expressive to provide the kinds of information which
may be necessary to support really robust debugging. In all of these cases
however, the use of DWARF version 2 features should not interfere in any
way with the interoperability (of GNU compilers) with generally available
"classic" (pre version 1) DWARF consumer tools (e.g. SVR4 SDB).
The DWARF generation enhancement for the GNU compiler(s) was initially
donated to the Free Software Foundation by Network Computing Devices.
(Thanks NCD!) Additional development and maintenance of dwarfout.c has
been largely supported (i.e. funded) by Intel Corporation. (Thanks Intel!)
If you have questions or comments about the DWARF generation feature, please
send mail to me <rfg@netcom.com>. I will be happy to investigate any bugs
reported and I may even provide fixes (but of course, I can make no promises).
The DWARF debugging information produced by GCC may deviate in a few minor
(but perhaps significant) respects from the DWARF debugging information
currently produced by other C compilers. A serious attempt has been made
however to conform to the published specifications, to existing practice,
and to generally accepted norms in the GNU implementation of DWARF.
** IMPORTANT NOTE ** ** IMPORTANT NOTE ** ** IMPORTANT NOTE **
Under normal circumstances, the DWARF information generated by the GNU
compilers (in an assembly language file) is essentially impossible for
a human being to read. This fact can make it very difficult to debug
certain DWARF-related problems. In order to overcome this difficulty,
a feature has been added to dwarfout.c (enabled by the -fverbose-asm
option) which causes additional comments to be placed into the assembly
language output file, out to the right-hand side of most bits of DWARF
material. The comments indicate (far more clearly that the obscure
DWARF hex codes do) what is actually being encoded in DWARF. Thus, the
-fverbose-asm option can be highly useful for those who must study the
DWARF output from the GNU compilers in detail.
---------
(Footnote: Within this file, the term `Debugging Information Entry' will
be abbreviated as `DIE'.)
Release Notes (aka known bugs)
-------------------------------
In one very obscure case involving dynamically sized arrays, the DWARF
"location information" for such an array may make it appear that the
array has been totally optimized out of existence, when in fact it
*must* actually exist. (This only happens when you are using *both* -g
*and* -O.) This is due to aggressive dead store elimination in the
compiler, and to the fact that the DECL_RTL expressions associated with
variables are not always updated to correctly reflect the effects of
GCC's aggressive dead store elimination.
-------------------------------
When attempting to set a breakpoint at the "start" of a function compiled
with -g1, the debugger currently has no way of knowing exactly where the
end of the prologue code for the function is. Thus, for most targets,
all the debugger can do is to set the breakpoint at the AT_low_pc address
for the function. But if you stop there and then try to look at one or
more of the formal parameter values, they may not have been "homed" yet,
so you may get inaccurate answers (or perhaps even addressing errors).
Some people may consider this simply a non-feature, but I consider it a
bug, and I hope to provide some GNU-specific attributes (on function
DIEs) which will specify the address of the end of the prologue and the
address of the beginning of the epilogue in a future release.
-------------------------------
It is believed at this time that old bugs relating to the AT_bit_offset
values for bit-fields have been fixed.
There may still be some very obscure bugs relating to the DWARF description
of type `long long' bit-fields for target machines (e.g. 80x86 machines)
where the alignment of type `long long' data objects is different from
(and less than) the size of a type `long long' data object.
Please report any problems with the DWARF description of bit-fields as you
would any other GCC bug. (Procedures for bug reporting are given in the
GNU C compiler manual.)
--------------------------------
At this time, GCC does not know how to handle the GNU C "nested functions"
extension. (See the GCC manual for more info on this extension to ANSI C.)
--------------------------------
The GNU compilers now represent inline functions (and inlined instances
thereof) in exactly the manner described by the current DWARF version 2
(draft) specification. The version 1 specification for handling inline
functions (and inlined instances) was known to be brain-damaged (by the
PLSIG) when the version 1 spec was finalized, but it was simply too late
in the cycle to get it removed before the version 1 spec was formally
released to the public (by UI).
--------------------------------
At this time, GCC does not generate the kind of really precise information
about the exact declared types of entities with signed integral types which
is required by the current DWARF draft specification.
Specifically, the current DWARF draft specification seems to require that
the type of an non-unsigned integral bit-field member of a struct or union
type be represented as either a "signed" type or as a "plain" type,
depending upon the exact set of keywords that were used in the
type specification for the given bit-field member. It was felt (by the
UI/PLSIG) that this distinction between "plain" and "signed" integral types
could have some significance (in the case of bit-fields) because ANSI C
does not constrain the signedness of a plain bit-field, whereas it does
constrain the signedness of an explicitly "signed" bit-field. For this
reason, the current DWARF specification calls for compilers to produce
type information (for *all* integral typed entities... not just bit-fields)
which explicitly indicates the signedness of the relevant type to be
"signed" or "plain" or "unsigned".
Unfortunately, the GNU DWARF implementation is currently incapable of making
such distinctions.
--------------------------------
Known Interoperability Problems
-------------------------------
Although the GNU implementation of DWARF conforms (for the most part) with
the current UI/PLSIG DWARF version 1 specification (with many compatible
version 2 features added in as "vendor specific extensions" just for good
measure) there are a few known cases where GCC's DWARF output can cause
some confusion for "classic" (pre version 1) DWARF consumers such as the
System V Release 4 SDB debugger. These cases are described in this section.
--------------------------------
The DWARF version 1 specification includes the fundamental type codes
FT_ext_prec_float, FT_complex, FT_dbl_prec_complex, and FT_ext_prec_complex.
Since GNU C is only a C compiler (and since C doesn't provide any "complex"
data types) the only one of these fundamental type codes which GCC ever
generates is FT_ext_prec_float. This fundamental type code is generated
by GCC for the `long double' data type. Unfortunately, due to an apparent
bug in the SVR4 SDB debugger, SDB can become very confused wherever any
attempt is made to print a variable, parameter, or field whose type was
given in terms of FT_ext_prec_float.
(Actually, SVR4 SDB fails to understand *any* of the four fundamental type
codes mentioned here. This will fact will cause additional problems when
there is a GNU FORTRAN front-end.)
--------------------------------
In general, it appears that SVR4 SDB is not able to effectively ignore
fundamental type codes in the "implementation defined" range. This can
cause problems when a program being debugged uses the `long long' data
type (or the signed or unsigned varieties thereof) because these types
are not defined by ANSI C, and thus, GCC must use its own private fundamental
type codes (from the implementation-defined range) to represent these types.
--------------------------------
General GNU DWARF extensions
----------------------------
In the current DWARF version 1 specification, no mechanism is specified by
which accurate information about executable code from include files can be
properly (and fully) described. (The DWARF version 2 specification *does*
specify such a mechanism, but it is about 10 times more complicated than
it needs to be so I'm not terribly anxious to try to implement it right
away.)
In the GNU implementation of DWARF version 1, a fully downward-compatible
extension has been implemented which permits the GNU compilers to specify
which executable lines come from which files. This extension places
additional information (about source file names) in GNU-specific sections
(which should be totally ignored by all non-GNU DWARF consumers) so that
this extended information can be provided (to GNU DWARF consumers) in a way
which is totally transparent (and invisible) to non-GNU DWARF consumers
(e.g. the SVR4 SDB debugger). The additional information is placed *only*
in specialized GNU-specific sections, where it should never even be seen
by non-GNU DWARF consumers.
To understand this GNU DWARF extension, imagine that the sequence of entries
in the .lines section is broken up into several subsections. Each contiguous
sequence of .line entries which relates to a sequence of lines (or statements)
from one particular file (either a `base' file or an `include' file) could
be called a `line entries chunk' (LEC).
For each LEC there is one entry in the .debug_srcinfo section.
Each normal entry in the .debug_srcinfo section consists of two 4-byte
words of data as follows:
(1) The starting address (relative to the entire .line section)
of the first .line entry in the relevant LEC.
(2) The starting address (relative to the entire .debug_sfnames
section) of a NUL terminated string representing the
relevant filename. (This filename name be either a
relative or an absolute filename, depending upon how the
given source file was located during compilation.)
Obviously, each .debug_srcinfo entry allows you to find the relevant filename,
and it also points you to the first .line entry that was generated as a result
of having compiled a given source line from the given source file.
Each subsequent .line entry should also be assumed to have been produced
as a result of compiling yet more lines from the same file. The end of
any given LEC is easily found by looking at the first 4-byte pointer in
the *next* .debug_srcinfo entry. That next .debug_srcinfo entry points
to a new and different LEC, so the preceding LEC (implicitly) must have
ended with the last .line section entry which occurs at the 2 1/2 words
just before the address given in the first pointer of the new .debug_srcinfo
entry.
The following picture may help to clarify this feature. Let's assume that
`LE' stands for `.line entry'. Also, assume that `* 'stands for a pointer.
.line section .debug_srcinfo section .debug_sfnames section
----------------------------------------------------------------
LE <---------------------- *
LE * -----------------> "foobar.c" <---
LE |
LE |
LE <---------------------- * |
LE * -----------------> "foobar.h" <| |

LE | |
LE <---------------------- * | |
LE * ------------------------------- |

In effect, each entry in the .debug_srcinfo section points to *both* a
filename (in the .debug_sfnames section) and to the start of a block of
consecutive LEs (in the .line section).
Note that just like in the .line section, there are specialized first and
last entries in the .debug_srcinfo section for each object file. These
special first and last entries for the .debug_srcinfo section are very
different from the normal .debug_srcinfo section entries. They provide
additional information which may be helpful to a debugger when it is
interpreting the data in the .debug_srcinfo, .debug_sfnames, and .line
sections.
The first entry in the .debug_srcinfo section for each compilation unit
consists of five 4-byte words of data. The contents of these five words
should be interpreted (by debuggers) as follows:
(1) The starting address (relative to the entire .line section)
of the .line section for this compilation unit.
(2) The starting address (relative to the entire .debug_sfnames
section) of the .debug_sfnames section for this compilation
unit.
(3) The starting address (in the execution virtual address space)
of the .text section for this compilation unit.
(4) The ending address plus one (in the execution virtual address
space) of the .text section for this compilation unit.
(5) The date/time (in seconds since midnight 1/1/70) at which the
compilation of this compilation unit occurred. This value
should be interpreted as an unsigned quantity because gcc
might be configured to generate a default value of 0xffffffff
in this field (in cases where it is desired to have object
files created at different times from identical source files
be byte-for-byte identical). By default, these timestamps
are *not* generated by dwarfout.c (so that object files
compiled at different times will be byte-for-byte identical).
If you wish to enable this "timestamp" feature however, you
can simply place a #define for the symbol `DWARF_TIMESTAMPS'
in your target configuration file and then rebuild the GNU
compiler(s).
Note that the first string placed into the .debug_sfnames section for each
compilation unit is the name of the directory in which compilation occurred.
This string ends with a `/' (to help indicate that it is the pathname of a
directory). Thus, the second word of each specialized initial .debug_srcinfo
entry for each compilation unit may be used as a pointer to the (string)
name of the compilation directory, and that string may in turn be used to
"absolutize" any relative pathnames which may appear later on in the
.debug_sfnames section entries for the same compilation unit.
The fifth and last word of each specialized starting entry for a compilation
unit in the .debug_srcinfo section may (depending upon your configuration)
indicate the date/time of compilation, and this may be used (by a debugger)
to determine if any of the source files which contributed code to this
compilation unit are newer than the object code for the compilation unit
itself. If so, the debugger may wish to print an "out-of-date" warning
about the compilation unit.
The .debug_srcinfo section associated with each compilation will also have
a specialized terminating entry. This terminating .debug_srcinfo section
entry will consist of the following two 4-byte words of data:
(1) The offset, measured from the start of the .line section to
the beginning of the terminating entry for the .line section.
(2) A word containing the value 0xffffffff.
--------------------------------
In the current DWARF version 1 specification, no mechanism is specified by
which information about macro definitions and un-definitions may be provided
to the DWARF consumer.
The DWARF version 2 (draft) specification does specify such a mechanism.
That specification was based on the GNU ("vendor specific extension")
which provided some support for macro definitions and un-definitions,
but the "official" DWARF version 2 (draft) specification mechanism for
handling macros and the GNU implementation have diverged somewhat. I
plan to update the GNU implementation to conform to the "official"
DWARF version 2 (draft) specification as soon as I get time to do that.
Note that in the GNU implementation, additional information about macro
definitions and un-definitions is *only* provided when the -g3 level of
debug-info production is selected. (The default level is -g2 and the
plain old -g option is considered to be identical to -g2.)
GCC records information about macro definitions and undefinitions primarily
in a section called the .debug_macinfo section. Normal entries in the
.debug_macinfo section consist of the following three parts:
(1) A special "type" byte.
(2) A 3-byte line-number/filename-offset field.
(3) A NUL terminated string.
The interpretation of the second and third parts is dependent upon the
value of the leading (type) byte.
The type byte may have one of four values depending upon the type of the
.debug_macinfo entry which follows. The 1-byte MACINFO type codes presently
used, and their meanings are as follows:
MACINFO_start A base file or an include file starts here.
MACINFO_resume The current base or include file ends here.
MACINFO_define A #define directive occurs here.
MACINFO_undef A #undef directive occur here.
(Note that the MACINFO_... codes mentioned here are simply symbolic names
for constants which are defined in the GNU dwarf.h file.)
For MACINFO_define and MACINFO_undef entries, the second (3-byte) field
contains the number of the source line (relative to the start of the current
base source file or the current include files) when the #define or #undef
directive appears. For a MACINFO_define entry, the following string field
contains the name of the macro which is defined, followed by its definition.
Note that the definition is always separated from the name of the macro
by at least one whitespace character. For a MACINFO_undef entry, the
string which follows the 3-byte line number field contains just the name
of the macro which is being undef'ed.
For a MACINFO_start entry, the 3-byte field following the type byte contains
the offset, relative to the start of the .debug_sfnames section for the
current compilation unit, of a string which names the new source file which
is beginning its inclusion at this point. Following that 3-byte field,
each MACINFO_start entry always contains a zero length NUL terminated
string.
For a MACINFO_resume entry, the 3-byte field following the type byte contains
the line number WITHIN THE INCLUDING FILE at which the inclusion of the
current file (whose inclusion ends here) was initiated. Following that
3-byte field, each MACINFO_resume entry always contains a zero length NUL
terminated string.
Each set of .debug_macinfo entries for each compilation unit is terminated
by a special .debug_macinfo entry consisting of a 4-byte zero value followed
by a single NUL byte.
--------------------------------
In the current DWARF draft specification, no provision is made for providing
a separate level of (limited) debugging information necessary to support
tracebacks (only) through fully-debugged code (e.g. code in system libraries).
A proposal to define such a level was submitted (by me) to the UI/PLSIG.
This proposal was rejected by the UI/PLSIG for inclusion into the DWARF
version 1 specification for two reasons. First, it was felt (by the PLSIG)
that the issues involved in supporting a "traceback only" subset of DWARF
were not well understood. Second, and perhaps more importantly, the PLSIG
is already having enough trouble agreeing on what it means to be "conforming"
to the DWARF specification, and it was felt that trying to specify multiple
different *levels* of conformance would only complicate our discussions of
this already divisive issue. Nonetheless, the GNU implementation of DWARF
provides an abbreviated "traceback only" level of debug-info production for
use with fully-debugged "system library" code. This level should only be
used for fully debugged system library code, and even then, it should only
be used where there is a very strong need to conserve disk space. This
abbreviated level of debug-info production can be used by specifying the
-g1 option on the compilation command line.
--------------------------------
As mentioned above, the GNU implementation of DWARF currently uses the DWARF
version 2 (draft) approach for inline functions (and inlined instances
thereof). This is used in preference to the version 1 approach because
(quite simply) the version 1 approach is highly brain-damaged and probably
unworkable.
--------------------------------
GNU DWARF Representation of GNU C Extensions to ANSI C
------------------------------------------------------
The file dwarfout.c has been designed and implemented so as to provide
some reasonable DWARF representation for each and every declarative
construct which is accepted by the GNU C compiler. Since the GNU C
compiler accepts a superset of ANSI C, this means that there are some
cases in which the DWARF information produced by GCC must take some
liberties in improvising DWARF representations for declarations which
are only valid in (extended) GNU C.
In particular, GNU C provides at least three significant extensions to
ANSI C when it comes to declarations. These are (1) inline functions,
and (2) dynamic arrays, and (3) incomplete enum types. (See the GCC
manual for more information on these GNU extensions to ANSI C.) When
used, these GNU C extensions are represented (in the generated DWARF
output of GCC) in the most natural and intuitively obvious ways.
In the case of inline functions, the DWARF representation is exactly as
called for in the DWARF version 2 (draft) specification for an identical
function written in C++; i.e. we "reuse" the representation of inline
functions which has been defined for C++ to support this GNU C extension.
In the case of dynamic arrays, we use the most obvious representational
mechanism available; i.e. an array type in which the upper bound of
some dimension (usually the first and only dimension) is a variable
rather than a constant. (See the DWARF version 1 specification for more
details.)
In the case of incomplete enum types, such types are represented simply
as TAG_enumeration_type DIEs which DO NOT contain either AT_byte_size
attributes or AT_element_list attributes.
--------------------------------
Future Directions
-----------------
The codes, formats, and other paraphernalia necessary to provide proper
support for symbolic debugging for the C++ language are still being worked
on by the UI/PLSIG. The vast majority of the additions to DWARF which will
be needed to completely support C++ have already been hashed out and agreed
upon, but a few small issues (e.g. anonymous unions, access declarations)
are still being discussed. Also, we in the PLSIG are still discussing
whether or not we need to do anything special for C++ templates. (At this
time it is not yet clear whether we even need to do anything special for
these.)
Unfortunately, as mentioned above, there are quite a few problems in the
g++ front end itself, and these are currently responsible for severely
restricting the progress which can be made on adding DWARF support
specifically for the g++ front-end. Furthermore, Richard Stallman has
expressed the view that C++ friendships might not be important enough to
describe (in DWARF). This view directly conflicts with both the DWARF
version 1 and version 2 (draft) specifications, so until this small
misunderstanding is cleared up, DWARF support for g++ is unlikely.
With regard to FORTRAN, the UI/PLSIG has defined what is believed to be a
complete and sufficient set of codes and rules for adequately representing
all of FORTRAN 77, and most of Fortran 90 in DWARF. While some support for
this has been implemented in dwarfout.c, further implementation and testing
will have to await the arrival of the GNU Fortran front-end (which is
currently in early alpha test as of this writing).
GNU DWARF support for other languages (i.e. Pascal and Modula) is a moot
issue until there are GNU front-ends for these other languages.
GNU DWARF support for DWARF version 2 will probably not be attempted until
such time as the version 2 specification is finalized. (More work needs
to be done on the version 2 specification to make the new "abbreviations"
feature of version 2 more easily implementable. Until then, it will be
a royal pain the ass to implement version 2 "abbreviations".) For the
time being, version 2 features will be added (in a version 1 compatible
manner) when and where these features seem necessary or extremely desirable.
As currently defined, DWARF only describes a (binary) language which can
be used to communicate symbolic debugging information from a compiler
through an assembler and a linker, to a debugger. There is no clear
specification of what processing should be (or must be) done by the
assembler and/or the linker. Fortunately, the role of the assembler
is easily inferred (by anyone knowledgeable about assemblers) just by
looking at examples of assembly-level DWARF code. Sadly though, the
allowable (or required) processing steps performed by a linker are
harder to infer and (perhaps) even harder to agree upon. There are
several forms of very useful `post-processing' steps which intelligent
linkers *could* (in theory) perform on object files containing DWARF,
but any and all such link-time transformations are currently both disallowed
and unspecified.
In particular, possible link-time transformations of DWARF code which could
provide significant benefits include (but are not limited to):
Commonization of duplicate DIEs obtained from multiple input
(object) files.
Cross-compilation type checking based upon DWARF type information
for objects and functions.
Other possible `compacting' transformations designed to save disk
space and to reduce linker & debugger I/O activity.

This is a partial list of how `gcc -traditional' disagrees with
traditional C compilers (perhaps only some of them). Most of these
differences are not bugs.
---------------------------------------------------------------------------
K&R-1 (2.4.3) says:
"If the character following a backslash is not one of those
specified {in the table above}, the backslash is ignored."
Up until recently, `gcc -traditional' complained about \x \a and \v
appearing in a character or string literal. I believe however that
this non-feature has been eliminated (recently).
---------------------------------------------------------------------------
When in -traditional mode, gcc allows the following erroneous pair of
declarations to appear together in a given scope:
typedef int foo;
typedef foo foo;
---------------------------------------------------------------------------
K&R-1 (8.5) says:
"No field may be wider than a word."
Gcc however allows:
struct S { int i:33; };
---------------------------------------------------------------------------
In K&R-1 there is no restriction against comments crossing include file
boundaries. Gcc however doesn't allow this, even when in -traditional mode.
---------------------------------------------------------------------------
Regarding the length of identifiers, K&R-1 (2.2) says:
"No more than the first eight characters are significant,
although more may be used."
Gcc treats all characters of identifiers as significant, even when in
-traditional mode.
---------------------------------------------------------------------------
K&R-1 (2.2) says:
"An identifier is a sequence of letters and digits; the first
character must be a letter. The underscore _ counts as a letter."
Gcc also allows dollar signs in identifiers. (This may also be an issue
for the -pedantic option.)

This is a collection of things that test suites have
said were "wrong" with GCC--but that I don't agree with.
First, test suites sometimes test for compatibility with
traditional C. GCC with -traditional is not completely
compatible with traditional C, and in some ways I think it
should not be.
* K&R C allowed \x to appear in a string literal (or character
literal?) even in cases where it is *not* followed by a sequence of
hex digits. I'm not convinced this is desirable.
* K&R compilers allow comments to cross over an inclusion boundary (i.e.
started in an include file and ended in the including file).
I think this would be quite ugly and can't imagine it could
be needed.
Sometimes tests disagree with GCC's interpretation of the ANSI standard.
* One test claims that this function should return 1.
enum {A, B} foo;
func (enum {B, A} arg)
{
return B;
}
I think it should return 0, because the definition of B that
applies is the one in func.
* Some tests report failure when the compiler does not produce
an error message for a certain program.
ANSI C requires a "diagnostic" message for certain kinds of invalid
programs, but a warning counts as a diagnostic. If GCC produces
a warning but not an error, that is correct ANSI support.
When test suites call this "failure", the tests are broken.

KEEPING TRACK OF EXPANSIONS
In order to clean out expansions corresponding to statements inside
"{(...)}" constructs we have to keep track of all expansions. The
cleanup is needed when an automatic, or implicit, expansion on
iterator, say X, happens to a statement which contains a {(...)}
form with a statement already expanded on X. In this case we have
to go back and cleanup the inner expansion. This can be further
complicated by the fact that {(...)} can be nested.
To make this cleanup possible, we keep lists of all expansions, and
to make it work for nested constructs, we keep a stack. The list at
the top of the stack (ITER_STACK.CURRENT_LEVEL) corresponds to the
currently parsed level. All expansions of the levels below the
current one are kept in one list whose head is pointed to by
ITER_STACK.SUBLEVEL_FIRST (SUBLEVEL_LAST is there for making merges
easy). The process works as follows:
-- On "({" a new node is added to the stack by PUSH_ITERATOR_STACK.
The sublevel list is not changed at this point.
-- On "})" the list for the current level is appended to the sublevel
list.
-- On ";" sublevel lists are appended to the current level lists.
The reason is this: if they have not been superseded by the
expansion at the current level, they still might be
superseded later by the expansion on the higher level.
The levels do not have to distinguish levels below, so we
can merge the lists together. */

## Supposedly not needed now that xm-sysv4.h includes alloc.h for Metaware.
### NCR3000 ships with a MetaWare compiler installed as CC, which chokes and
### dies all over the place on GCC source. However, the AT&T compiler,
### crusty as it is, can be used to bootstrap GCC. It can be found in
### /usr/ccs/ATT/cc. It is also used to compile the things that should

# Some versions of SVR4 have an alloca in /usr/ucblib/libucb.a, and if we are
# careful to link that in after libc we can use it, but since newer versions of
# SVR4 are dropping libucb, it is better to just use the portable C version for
# bootstrapping. Do this by defining ALLOCA.
