- arm64 doesn't build (missing __aarch64_swp1_acq in kernels)
- mips cpu targets all build (maybe not all ports)
- powerpc builds (maybe not all ports)
- fix path to compiler-specific includes
- missing (void) for (older) C
- fix __is_signed/__is_signed_val change
- avoid compiler warning-as-errors
- add to existing COPTS.file values, instead of setting
- bump libgomp minor; functions were added
- add new 'compare' c++ header
- handle new analyzer subdirectory. set TARGET_MACHINE for lto-streamer-in.c.
remove params.list etc handling.
- coroutines.cc is another .cc not .c. adjust .PATH to suit.
- add new lto1 sources
- couple of files not in /arch/ subdirs missed in mknative update.
rs6000.c is still not merged.
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.
caveats:
- ABI issue between c++14 and c++17 fixed
- profile mode is removed from libstdc++
- -fno-common is now the default
new features:
- new flags -fallocation-dce, -fprofile-partial-training,
-fprofile-reproducible, -fprofile-prefix-path, and -fanalyzer
- many new compile and link time optimisations
- enhanced drive optimisations
- openacc 2.6 support
- openmp 5.0 features
- new warnings: -Wstring-compare and -Wzero-length-bounds
- extended warnings: -Warray-bounds, -Wformat-overflow,
-Wrestrict, -Wreturn-local-addr, -Wstringop-overflow,
-Warith-conversion, -Wmismatched-tags, and -Wredundant-tags
- some likely C2X features implemented
- more C++20 implemented
- many new arm & intel CPUs known
hundreds of reported bugs are fixed. full list of changes

use the default which includes a '.file "filename"' as the first name so
that the FILE symbols type is set to the real source file name. Needed
to make ctfconvert work.
OK mrg@.
XXX needs to be fed back to GNU.
release builds done for cobalt and evbmips64-eb
Provide an __eprol symbol in TEXT_START_SYMBOLS. MIPS overrides
TEXT_START_SYMBOLS so it misses out on the default definition of
this that does provide an __eprol symbol. Fixes linking of profiled
binaries.

OK: christos@
"nat/gdb_ptrace.h" defines PT_STEP as 9, if it is not defined. nat-ptrace.c
depends on this; inf_ptrace_target::resume() uses PT_STEP unconditionally
when its ``step'' argument is non-zero. Therefore,
- Add comment that nbsd-nat.c should include <sys/ptrace.h> directly,
instead of "nat/gdb_ptrace.h".
- Add gdb_assert(step == 0) in nbsd_nat_target::resume() ifndef PT_STEP,
before calling inf_ptrace_target::resume().
