merge GCC 12.4.0.

branches: 1.34.2;
initial merge of GCC 12.3.0.

this doesn't include any of the changes to the .c -> .cc files renamed,
and reverts our local changes to the vax port and libsanitizer subdir.
vax GCC was rewritten and our local fixes no longer are relevant, and
the new libsanitizer is more updated than our old one, and merging via
gcc10->gcc12 is not really possible.

unfortunately, our local changes to libsanitizer that aren't related
to the general update of those sources (ie, the netbsd code) will need
to be re-checked and perhaps re-ported.

merge GCC 10.5.0.

branches: 1.32.2;
merge GCC 10.4.0.

Add support for mipsn64 targets which build 64 bit binaries by default
on instead of n32

remove double arm64 netbsd target. add t-lse, though we don't
pull this out with mknative currently.

initial merge of GCC 10.3.0.

these three files are not yet finished merging:

gcc/config/rs6000/rs6000.c
libsanitizer/lsan/lsan_allocator.h
libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.h

our current GCC 9 sanitizers are newer than GCC 10's still, so that
may take a little to untease, so it's probable that more than
these 2 will need more changes.

rs6000.c has some changes related to ABI and supported functionality
that need to be merged forward.

- define __riscv__ again
- define *intptr_t in terms of 'long int' always
- move fixtfdi.c, fixunstfdi.c, floatditf.c, and floatunditf.c into t-netbsd64
- remove duplicated riscv case in config.gcc, reducing upstream diff as well
- regen riscv64 mknative

list a bunch of soft-fp as present in the current risc64 libgcc defs.mk.
this makes mknative-gcc work without breaking maya's manual work.

make ia64 build with gcc7:
- catch up tmake_file list for ia64-netbsd to gcc 7 standards
- don't build the "tf" extra size version on ia64 like x86.
- regen mknative files

- don't use arm unwind code for netbsd/earm. conflicts with native unwind.

Add RISC-V support.

Merge OR1K support from OR1K GCC 4.9 git tree and extend it to support NetBSD.

branches: 1.8.2;
Resolve conflicts

branches: 1.7.2;
add ia64-netbsd support.

coldfire does not want m68k/t-floatlib.
enable powerpc*-netbsd* -- ie, match ppc64.

merge GCC r208254.

merge gcc 4.8.2 r206687 (part 3).

merge gcc 4.8.2 r206687 (part 1).

Initial revision

merge GCC 8.4.0.

merge GCC 8.3.0 pass 1. will not compile yet. thare are still
about 25 files with merge issues.

- define __riscv__ again
- define *intptr_t in terms of 'long int' always
- move fixtfdi.c, fixunstfdi.c, floatditf.c, and floatunditf.c into t-netbsd64
- remove duplicated riscv case in config.gcc, reducing upstream diff as well
- regen riscv64 mknative

list a bunch of soft-fp as present in the current risc64 libgcc defs.mk.
this makes mknative-gcc work without breaking maya's manual work.

make ia64 build with gcc7:
- catch up tmake_file list for ia64-netbsd to gcc 7 standards
- don't build the "tf" extra size version on ia64 like x86.
- regen mknative files

- don't use arm unwind code for netbsd/earm. conflicts with native unwind.

set md_unwind_header=aarch64/aarch64-unwind.h for netbsd arm64.

first pass at merging GCC 7.4.0. unlikely to compile..

merge GCC 6.5. needs mknative as some new files appeared.

First pass at mknative for aarch64, based on mrg's work.

branches: 1.17.2; 1.17.4;
merge GCC 6.4.0. sanitizer stuff is probably busted, but most
other changes merged easily.

docs need to be regenerated with modern versions still.

merge GCC 5.5.0. this does not include updated man/info pages (yet).

branches: 1.15.6;
enable tf math (__float128)

The NetBSD libc provides the softfloat support which is duplicated in libgcc
and we prefer ours.

branches: 1.13.2;
enable some soft-fp for ia64, needed for libgcc. re-mknative-gcc.

merge GCC 5.4.0. (needs mknative, may not build yet.)

GCC now has stricter checks for invalid command-line options
New -Wunused-but-set-variable and -Wunused-but-set-parameter
warnings
Many platforms have been obsoleted
Link-time optimization improvements
A new switch -fstack-usage has been added

highlights from: http://gcc.gnu.org/gcc-4.7/changes.html

The -fconserve-space flag has been deprecated
Support for a new parameter --param case-values-threshold=n
was added
