on bi-parser.h. Not having it sometimes (only with `make -j') triggered
a bug suite that led to ordinary cpp output being put in .depend files.
Various bugs (the main one only with `make -j') prevented timely detection
of failure to build and install gnu/usr.bin/cc. Eventually the missing
${WORLDTMP}/usr/libexec/cpp caused ${WORLDTMP}/usr/bin/cpp to be invoked
by cc, and this version of cpp is not suitable for such invocation.
Ordinary cpp output was put in .depend files when cpp terminated options
processing before seeing the -M flag.
Cleaned up.
magic number byte ordering for FreeBSD. This makes "file" describe
our object files as "FreeBSD/i386 object" instead of as NetBSD
object files. In case this seems drastic and risky, Bruce points
out that the "ld -r -x" step that is done on every object file when
building libraries fixes the byte ordering in the same way. I have
been running with this patch for over a month and have seen no
problems.
With -O3, egcs generates such forward references.

"/usr/libexec/elf". Disable a.out support in libbfd. It's too
dangerous to leave it in. Some of the utilities think they can
handle a.out, but they generate bad object files.
These are equivalent to "fildq" and "fistpq" respectively. This
fixes the bad floating point object code that resulted after recent
changes in the compiler.

Partly fixed a potentially fatal bug involving the yacc header.
We generate eqn.cc (even if there is a version of it in the source
directory older than eqn.y) and a matching eqn.tab.h, but only use
the possibly-non-matching eqn.tab.h in the source directory. This
works because Cygnus's yacc happened to generate a y.tab.h identical
to the current generated one. The correct version will be used
when the wrong version is deleted from the source tree. Kludge to
get the header generated early enough. Yacc headers are mishandled
everywhere they are renamed (and used).

target. .ORDER doesn't work right, but is used for things related
to the depend target. It "works" for the depend target by skipping
the build of .depend when N >= 2 and there is a non-default
beforedepend target with no rules. Recent fixes made almost all
the beforedepend targets in the tree a no-op except for this bug.

Also copy the bfd.h header to an architecture specific directory
because there are two fundamental lines that differ (32-bit vs 64-bit)

The config.h for libbinutils generates the same on alpha as i386,
so I didn't change that (though I was tempted!).
support building it for variant architectures. It was already
becoming clear that the former structure was too rigid and didn't
scale well.
The usual sort of makefile magic arranges to .include an architecture
specific makefile "Makefile.${MACHINE_ARCH}" in each directory
where it exists. Also, sources will be found in each subdirectory
"${MACHINE_ARCH}" that exists. This is all taken care of automatically
by the top level "Makefile.inc0".
This all seems to work right for the i386 now. I have also converted
those alpha pieces already present to the new schema as best I
could.
Also: change the BINDIR on the i386 to /usr/libexec/elf for "ar"
and "ranlib". They are not object format independent enough to
put into /usr/bin.
a.out gas and the binutils gas (elf or a.out) with a single compiler.
This uses other infrastructure not yet committed, in order to support
both a.out and elf it needs to be able to get to both a.out and elf
gas, ld, libs, crt* etc. So for now, the support is pretty much dormant.
The new freebsd.h file is based on the old freebsd-elf.h file (which has a
long lineage, right back through linux and svr4 files). The change is
pretty dramatic from a gcc internals standpoint as it overrides a lot of
definitions in order to generate different output based on target mode.
There is potential for screw-ups, so please be on the lookout - gcc's
configuration mechanism wasn't really meant for this kind of thing.
It's believed to compile world etc just fine under both a.out and elf, can
handle global constructors and destructors, handles the differences in
a.out and elf stabs, and what sections things like exceptions go in.
The initial idea came from i386/osfrose.h which is a dual rose/elf format
target. These two are not as diverse as a.out and elf it would seem.
The cc front-end uses external configuration to determine default object
format (still being thrashed out, so read the source if you want to see
it so far), and has a '-aout' and '-elf' override command line switch.
There are some other internal switches that can be accessed, namely -maout,
-mno-aout, -munderscores and -mnounderscores. The underscore and local
symbol prefixing rules are controllable seperately to the output format.
(ie: it's possible to generate a.out without the _ prefixes on symbols and
also to generate elf with the _ prefixes. This isn't quite optimal, but
does seem to work pretty well, except the linkers don't always recognise
the local symbols without their normal names)
The default format is a.out (still), nobody should see any major changes.
With both elf and a.out tools and libraries installed:
