The non-standard C++0x type traits has_trivial_default_constructor,
has_trivial_copy_constructor and has_trivial_copy_assign have been
removed.
On ARM targets (arm*-*-*), a bug introduced in GCC 5 that affects
conformance to the procedure call standard (AAPCS) has been fixed.
Many optimiser improvements
DWARF-5 support.
Many new and enhanced warnings.
Warnings about format strings now underline the pertinent part of
the string, and can offer suggested fixes.
Several new warnings related to buffer overflows and buffer
truncation.
New __builtin_add_overflow_p, __builtin_sub_overflow_p,
__builtin_mul_overflow_p built-ins added that test for overflow.
The C++ front end has experimental support for all of the current
C++17 draft.
The -fverbose-asm option has been expanded to prints comments
showing the source lines that correspond to the assembly.
The gcc and g++ driver programs will now provide suggestions for
misspelled arguments to command-line options.
AArch64 specific:
GCC has been updated to the latest revision of the procedure call
standard (AAPCS64) to provide support for parameter passing when
data types have been over-aligned.
The ARMv8.2-A and ARMv8.3-A architecture are now supported.
ARM specific:
Support for the ARMv5 and ARMv5E architectures has been
deprecated (which have no known implementations).
A new command-line option -mpure-code has been added. It does not
allow constant data to be placed in code sections.
x86 specific:
Support for the AVX-512 4FMAPS, 4VNNIW, VPOPCNTDQ and Software
Guard Extensions (SGX) ISA extensions has been added.
PPC specific:
GCC now diagnoses inline assembly that clobbers register r2.
RISC-V specific:
Support for the RISC-V instruction set has been added.
SH specific:
Support for SH5/SH64 has been removed.
Support for SH2A has been enhanced.

No one defines TARGET_DEFAULT_CPU anymore. Use ENABLE_SHARED_LIBGCC
instead to determine whether GCC is configured for m68k or m68000.
This fixes C++ binaries on m68k, that require libgcc_s.
OK mrg
- move MD lwp "md_ktf" member into struct pcb. the pcb is used by
the gdb "bsd-kvm" target code to find the stack of each thread
and needs to be available in a well known location.
- implement aarch64_nbsd_supply_pcb() in GDB. makes basic gdb work
on a crash dump.
- remove '#if L_MD_KTF + 8 == L_MD_CPACR' conditional code, as there
is no more L_MD_KTF.
with this gdb has minimal working functionality with "target kvm",
and crash can at least "ps" on a crash dump.
ok skrll.
- publish per-cpu data
- publish a whole bunch of info in struct aarch64_sysctl_cpu_id
instead of various individual nodes (there are 16 total.)
- add MIDR extractor bits
- define ARMv8.2-A id_aa64mmfr2_el1 and id_aa64zfr0_el1 regs,
but avoid using them until we make sure they exist. (these
members are added to aarch64_sysctl_cpu_id to avoid future
compat issues.)
the arm32 and aarch32 version of these need to be adjusted as
well (and aarch32 data published at all.) still trying to
work out how to make the same userland binary running on a
real arm32 or an aarch32 system can work sanely here.
ok ryo@.

redo mknative-gcc for all ports. main changes include:
- "#define HAVE_CC_TLS 1" for most/all ports, thanks maya@
- "#define _GLIBCXX_HAVE_LDEXPL 1" and "#define _GLIBCXX_HAVE_TGMATH_H 1"
for many ports
- arm64 and amd64 had a broken c++config.h that disabled many things
- configargs.h has more normalisation
- ppc64 has a few things fixed, must have missed several mknative rounds
--
regen to pull out INTERNAL_CFLAGS.
--
pull -DHAVE_CC_TLS out of $(INTERNAL_CFLAGS) if it is there, and add
it to CPPFLAGS.
this fixes PR#53567 for me.
