a variety of bugs in binutils related to handling of 64-bit PPC ELF,
provides a GCC configuration for 64-bit PowerPC on FreeBSD, and
associated build systems tweaks.

MIPS-III because FreeBSD relies on a number of MIPS-III features; the ABI
default would be MIPS-I which we don't intend to support. Our old default
before I switched to using the ABI default was MIPS32.
o) Add TARGET_ABI to the MIPS toolchain build process. This sets the default
ABI to one of o32, n32 or n64. If it is not set, o32 is assumed as that is
the current default.
o) Set the default GCC cpu type to any specified TARGET_CPUTYPE. This is
necessary to have a working "cc" if e.g. mips64 is specified, as binutils
will refuse to link objects using different ISAs in some cases.
o) Add support for n32 and n64 ABIs to binutils and GCC.
o) Add additional required libgcc2 stubs for n32 and n64.
o) Add support for the "mips64r2" architecture to GCC. Add the "octeon"
o) When static linking, wrap default libraries in --start-group and
--end-group. This is required for static linking to work on n64 with the
interdependencies between libraries there. This is what other OSes that
support n64 seem to do, as well.
o) Fix our GCC spec to define __mips64 for 64-bit targets, not __mips64__, the
former being what libgcc, etc., check and the latter seemingly being a
misspelling of a hand merge from a Linux spec.
o) When no TARGET_CPUTYPE is specified at build time, make GCC take the default
ISA from the ABI. Our old defaults were too liberal and assumed that 64-bit
ABIs should default to the MIPS64 ISA and that 32-bit ABIs should default to
the MIPS32 ISA, when we are supporting or will support some systems based on
earlier 32-bit and 64-bit ISAs, most notably MIPS-III.
o) Merge a new opcode file (and support code) from a later version of binutils
and add flags and code necessary to support Octeon-specific instructions.
This should also make merging opcodes for other modern architectures easier.

- Get rid of ugly TARGET_CPU_DEFAULT default. 16 is MASK_DSP
and was set there due to my ignroance.
Use libssp_nonshared library to pull __stack_chk_fail_local symbol into
each library that needs it instead of pulling it from libc. GCC generates
local calls to this function which result in absolute relocations put into
position-independent code segment, making dynamic loader do extra work everys
time given shared library is being relocated and making affected text pages
non-shareable.

In particular, vendor sources that aren't ready for gnu99 should
still be compiled with gnu89. (Before r189824, these would have
generated warnings if you tried to compile them in gnu99 mode,
but the warnings went unheeded due to -Wno-error.)
This change was erronously ommitted from the r185690, and attempt
to simply add the prototype to string.h has revealed that several
contributed programs defined local prototypes for strndup(), controlled
by autoconfed config.h. So, manually change #undef HAVE_STRNDUP to
#define HAVE_STRNDUP 1. Next import of the corresponding program would
regenerate config.h, overriding the changes in this commit.

that the build failure was caused by a computer/sources date/time
mismatch that caused GCC tools to be mistakenly rebuilt again at
an inappropriate time during buildworld, re-linking them against
new libraries instead of host's installed libraries and thus making
them not runnable by the host. Normally they are only built in
the early stage of buildworld (build-tools) that links them against
shared libraries of the host, but if either the system clock or
modification date/time on source files is set incorrectly, make(1)
can be foolished into thinking that tools are stale and will rebuild
them again, now in the "target" environment which is not suitable
for building helper apps that are to be run during buildworld.

Also:
Switch FreeBSD to use libgcc_s.so.1.
Use dl_iterate_phdr to locate shared objects' exception frame
info instead of depending on older register_frame_info machinery.
This allows us to avoid depending on libgcc_s.so.1 in binaries
that do not use exception handling directly. As an additional
benefit it breaks circular libc <=> libgcc_s.so.1 dependency too.
Build newly added libgomp.so.1 library, the runtime support
bits for OpenMP.
Build LGPLed libssp library. Our libc provides our own
BSD-licensed SSP callbacks implementation, so this library
is only built to benefit applications that have hadcoded
knowledge of libssp.so and libssp_nonshared.a. When linked
in from command line, these libraries override libc
implementation.
'target'. Latter is problematic in particular as apparently FreeBSD's
bsd.prog.mk re-defines it under some circumstances. This causes an
unexpected failures like -dumpmachine not working for cc while working
fine for c++.
Do not re-define IN_GCC in multipe places, it gets inherited from
Makefile.in anyway.

in rev. 1.57. Fix this regression by making cc_tools a new-style
build-tool in Makefile.inc1. For details of what has been fixed,
please see the gnu/usr.bin/cc/cc_tools/Makefile,v 1.52 commit log.
Caught this by accidentally touching param.h while in the process
of cross-buildworld for amd64.
(bogus, application name space) mcount function name on amd64. Override
it here instead.
I've done it this way to avoid touching gcc source while 3.4 is in
progress, and this is the smallest, lowest impact I could come up with.
Adding a patch touches about 10-14 lines of Makefile, this touches only 1.
This will likely go away with the 3.4 import.
I spoke with Alexander about this a few days ago, but waited until after
sorting out some of the other bugs in the userland profiling.
Makeworld will add -static in the correct place if needed and possible.
Self-hosted builds can just use the system default.
Fixed some nearby style bugs (code unrelated to its comment, and comment
formatting).
idea after all.
Fix cross-builds and ia64 builds. gnu/lib/csu/Makefile is modified to
pre-include osreldate.h and gnu/usr.bin/cc/cc_tools/auto-host.h
will avoid including sys/param.h if __FreeBSD_version is already defined.
non-PIC libgcc.a. Linking non-pic code into a shared library is not
a good thing. It happens to break amd64 at compile time, and the ppc
folks want it too. The problem is mainly with C++ code, unwind-dw2.c
in particular. Most of the other functions in libgcc.a are self
contained so most of the time it isn't a problem. The dwarf2 unwinder
is not safe though since it does make global variable references.

give the cvs tree a surviving a 'make world'. One of the two diff chunks
is already in gcc-3.3, the other has been committed to gcc's HEAD and
is in the pipeline for gcc-3.3.1 (but has not been committed yet).
The first chunk simplifies an excessively complex assembler statement
when generating switch jump tables. The use of '.' causes as(1) to choke
on big files. Use a simpler form instead. This is only an issue for
TARGET_64BIT mode.
The second chunk fixes an internal compiler error when compiling
libc/stdio/vfprinf.c. While this is supposedly only an issue for
64 bit mode, it does touch the 32 bit i386 code paths, so this patch
is only applied for TARGET_ARCH == amd64 to keep the risks down.
Breaking gcc at the 11th hour would suck.
This will be removed when it is time to import gcc-3.3.

under way to move the remnants of the a.out toolchain to ports. As the
comment in src/Makefile said, this stuff is deprecated and one should not
expect this to remain beyond 4.0-REL. It has already lasted WAY beyond
that.
Notable exceptions:
gcc - I have not touched the a.out generation stuff there.
ldd/ldconfig - still have some code to interface with a.out rtld.
old as/ld/etc - I have not removed these yet, pending their move to ports.
some includes - necessary for ldd/ldconfig for now.

cc1plus can apparently be built if you happen to have
/usr/bin/gperf, or set CXX to point to a C++ compiler
that can build gperf(1) in the bootstrap-tools stage
of buildworld.
The problem is the GCC driver now turns STANDARD_EXEC_PREFIX into a relative
path -- "<basename argv[0]>/../../libexec" for our normal install location.
However, in the middle of `buildworld' we need
"<basename argv[0]>/../../../../libexec" due to the prefix we tell the GCC
driver. But either the GCC driver is buggy, or we are confusing it, as it
tries to exec "<basename argv[0]>/../../libexec/cpp0" as if it were installed
in the normal place (but isn't).
MD_EXEC_PREFIX is still absolute, so I'll use that for now. I would like to
later make it so MD_EXEC_PREFIX is set only for `buildworld', as
MD_EXEC_PREFIX is also in the search path for libraries. Don't ask me why!
Another way is to add ${OBJFORMAT_PATH} (as set in CROSSENV) to the PATH
in src/Makefile.inc's WMAKEENV.
bits. Also remove comment about keeping in sync with other instances in
the source tree -- it was too easy to get out of sync, so the other
instances now use this instance.
collect2 was added based on the need of -frepo. However, -frepo is currently
broken on -CURRENT (Gcc 2.95.4 20020320 [FreeBSD] / ld 2.12.0 [FreeBSD]
2002-04-10). It is also broken on RELENG_4 (Gcc 2.95.3 20010315 / ld
2.11.2 20010719), so there is no need to MFC collect2 there yet. I have
a feeling the brokeness is due to the wide difference between the libiberty
bits of Gcc 2.95 and the later ld.
