As of GCC 2.95 these files: choose-temp.c demangle.h getopt.h obstack.c pexecute.c cplus-dem.c getopt.c getopt1.c obstack.h were removed from the GCC compilers proper to libiberty. To continue our revision history, and to keep from having to import all of libiberty, they are imported here as if they were never moved.

/* In order to allow a single demangler executable to demangle strings

using various common values of CPLUS_MARKER, as well as any specific
|
|
one set at compile time, we maintain a string containing all the
|
|
commonly used ones, and check to see if the marker we are looking for
|
|
is in that string. CPLUS_MARKER is usually '$' on systems where the
|
|
assembler can deal with that. Where the assembler can't, it's usually
|
|
'.' (but on many systems '.' is used for other things). We put the
|
|
current defined CPLUS_MARKER first (which defaults to '$'), followed
|
|
by the next most common value, followed by an explicit '$' in case
|
|
the value of CPLUS_MARKER is not '$'.
|
|
|
|
We could avoid this if we could just get g++ to tell us what the actual
|
|
cplus marker character is as part of the debug information, perhaps by
|
|
ensuring that it is the character that terminates the gcc<n>_compiled
|

marker symbol (FIXME). */

LOCAL FUNCTION

demangle_signature -- demangle the signature part of a mangled name

SYNOPSIS

|
static int

|

|
|
|
|
DESCRIPTION
|
|
|
|
Consume and demangle the signature portion of the mangled name.
|
|
|
|
DECLP is the string where demangled output is being built. At
|
|
entry it contains the demangled root name from the mangled name
|
|
prefix. I.E. either a demangled operator name or the root function
|
|
name. In some special cases, it may contain nothing.
|
|
|
|
*MANGLED points to the current unconsumed location in the mangled
|
|
name. As tokens are consumed and demangling is performed, the
|
|
pointer is updated to continuously point at the next token to
|
|
be consumed.
|
|
|
|
Demangling GNU style mangled names is nasty because there is no
|
|
explicit token that marks the start of the outermost function
|
|
argument list. */

SYNOPSIS

static int

|
demangle_class (struct work_stuff *work, const char **mangled,
|
|
strint *declp)
|
|
|
|
DESCRIPTION
|
|
|
|
DECLP points to the buffer into which demangling is being done.
|
|
|
|
*MANGLED points to the current token to be demangled. On input,
|
|
it points to a mangled class (I.E. "3foo", "13verylongclass", etc.)
|
|
On exit, it points to the next token after the mangled class on
|
|
success, or the first unconsumed token on failure.
|
|
|
|
If the CONSTRUCTOR or DESTRUCTOR flags are set in WORK, then
|
|
we are demangling a constructor or destructor. In this case
|
|
we prepend "class::class" or "class::~class" to DECLP.
|
|
|
|
Otherwise, we prepend "class::" to the current DECLP.
|
|
|
|
Reset the constructor/destructor flags once they have been
|
|
"consumed". This allows demangle_class to be called later during
|
|
the same demangling, to do normal class demangling.
|
|
|
|
Returns 1 if demangling is successful, 0 otherwise.

LOCAL FUNCTION

SYNOPSIS

|
static int

|
demangle_prefix (struct work_stuff *work, const char **mangled,

string *declp);
|
|
|
|
DESCRIPTION
|
|
|
|
Consume and demangle the prefix of the mangled name.
|
|
|
|
DECLP points to the string buffer into which demangled output is
|
|
placed. On entry, the buffer is empty. On exit it contains
|
|
the root function name, the demangled operator name, or in some
|
|
special cases either nothing or the completely demangled result.
|
|
|
|
MANGLED points to the current pointer into the mangled name. As each
|
|
token of the mangled name is consumed, it is updated. Upon entry
|
|
the current mangled name pointer points to the first character of
|
|
the mangled name. Upon exit, it should point to the first character
|
|
of the signature if demangling was successful, or to the first
|
|
unconsumed character if demangling of the prefix was unsuccessful.
|
|
|
|
Returns 1 on success, 0 otherwise.

SYNOPSIS
|
|
|
|
static int
|
|
demangle_qualified (struct work_stuff *, const char *mangled,
|
|
string *result, int isfuncname, int append);
|
|
|
|
DESCRIPTION
|
|
|
|
Demangle a qualified name, such as "Q25Outer5Inner" which is
|
|
the mangled form of "Outer::Inner". The demangled output is
|
|
prepended or appended to the result string according to the
|
|
state of the append flag.
|
|
|
|
If isfuncname is nonzero, then the qualified name we are building
|
|
is going to be used as a member function name, so if it is a
|
|
constructor or destructor function, append an appropriate
|
|
constructor or destructor name. I.E. for the above example,
|
|
the result for use as a constructor is "Outer::Inner::Inner"
|
|
and the result for use as a destructor is "Outer::Inner::~Inner".

LOCAL FUNCTION
|
|
|
|
get_count -- convert an ascii count to integer, consuming tokens
|
|
|
|
SYNOPSIS
|
|
|
|
static int
|
|
get_count (const char **type, int *count)
|
|
|
|
DESCRIPTION
|
|
|
|
Assume that *type points at a count in a mangled name; set
|
|
*count to its value, and set *type to the next character after
|
|
the count. There are some weird rules in effect here.
|
|
|
|
If *type does not point at a string of digits, return zero.
|
|
|
|
If *type points at a string of digits followed by an
|
|
underscore, set *count to their value as an integer, advance
|
|
*type to point *after the underscore, and return 1.
|
|
|
|
If *type points at a string of digits not followed by an
|
|
underscore, consume only the first digit. Set *count to its
|
|
value as an integer, leave *type pointing after that digit,
|
|
and return 1.
|
|
|
|
The excuse for this odd behavior: in the ARM and HP demangling
|
|
styles, a type can be followed by a repeat count of the form
|
|
`Nxy', where:
|
|
|
|
`x' is a single digit specifying how many additional copies
|
|
of the type to append to the argument list, and
|
|
|
|
`y' is one or more digits, specifying the zero-based index of
|
|
the first repeated argument in the list. Yes, as you're
|
|
unmangling the name you can figure this out yourself, but
|
|
it's there anyway.
|
|
|
|
So, for example, in `bar__3fooFPiN51', the first argument is a
|
|
pointer to an integer (`Pi'), and then the next five arguments
|
|
are the same (`N5'), and the first repeat is the function's
|
|
second argument (`1').

Note that g++ differs significantly from ARM and lucid style mangling

with regards to references to previously seen types. For example, given

the source fragment:
|
|
|
|
class foo {
|
|
public:
|
|
foo::foo (int, foo &ia, int, foo &ib, int, foo &ic);
|
|
};
|
|
|
|
foo::foo (int, foo &ia, int, foo &ib, int, foo &ic) { ia = ib = ic; }
|
|
void foo (int, foo &ia, int, foo &ib, int, foo &ic) { ia = ib = ic; }
|
|
|
|
g++ produces the names:
|
|
|
|
__3fooiRT0iT2iT2
|
|
foo__FiR3fooiT1iT1
|
|
|
|
while lcc (and presumably other ARM style compilers as well) produces:
|
|
|
|
foo__FiR3fooT1T2T1T2
|
|
__ct__3fooFiR3fooT1T2T1T2
|
|
|
|
Note that g++ bases its type numbers starting at zero and counts all
|
|
previously seen types, while lucid/ARM bases its type numbers starting
|
|
at one and only considers types after it has seen the 'F' character
|
|
indicating the start of the function args. For lucid/ARM style, we
|
|
account for this difference by discarding any previously seen types when
|
|
we see the 'F' character, and subtracting one from the type number
|
|
reference.

Note that, since HP's compiler generates object code straight from

|
C++ source, without going through an assembler, its mangled
|
|
identifiers can use all sorts of characters that no assembler would
|
|
tolerate, so the alphabet this function creates is a little odd.
|
|
Here are some sample mangled identifiers offered by HP:
|
|
|
|
typeid*__XT24AddressIndExpClassMember_
|
|
[Vftptr]key:__dt__32OrdinaryCompareIndExpClassMemberFv
|
|
__ct__Q2_9Elf64_Dyn18{unnamed.union.#1}Fv
|
|
|
|
This still seems really weird to me, since nowhere else in this
|
|
file is there anything to recognize curly brackets, parens, etc.
|
|
I've talked with Srikanth <srikanth@cup.hp.com>, and he assures me
|
|
this is right, but I still strongly suspect that there's a
|
|
misunderstanding here.
|
|
|
|
If we decide it's better for c++filt to use HP's assembler syntax
|
|
to scrape identifiers out of its input, here's the definition of
|
|
the symbol name syntax from the HP assembler manual:
|
|
|
|
Symbols are composed of uppercase and lowercase letters, decimal
|
|
digits, dollar symbol, period (.), ampersand (&), pound sign(#) and
|
|
underscore (_). A symbol can begin with a letter, digit underscore or
|
|
dollar sign. If a symbol begins with a digit, it must contain a
|
|
non-digit character.
