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.
we can't build things even when cross-compiling because of missing header
files (like stdatomic.h). Really all the md/ad header files now will be
installed when mkgcccmds=no, but I've only fixed m68k.
NetBSD.
This brings us resolving for dynamically loaded libraries and makes
tests/libexec/ld.elf_so/t_thread_local_dtor pass.

that when traps are marked as invalid, we never use them
for anything except output from the trap command.
Fixes issues where sub-shells of shells which use traps
(eg: to trap SIGPIPE) can end up looping forever if the
signal occurs in a sub-shell (where the trap is supposed
to be reset to its default). Reported, and mostly
analyzed by Martijn Dekker.
- avoid calloc, use bozomalloc
- minor CSE
- fix bozoprefs->size setting when increasing the size (new total was
being added to the prior total.) found by clang static analyzer
from rajeev_v_pillai.
pass httpd to size_arrays() now.
free(NULL) is legal.
- bozostrnsep() may return with "in = NULL", so check for it.
- nul terminating in bozo_escape_rfc3986() can be simpler
- don't use uniinit variables in check_remap()
- don't use re-used freed data in check_virtual(). this one is tricky as
the original code was:
free(request->hr_file);
request->hr_file = bozostrdup(httpd, request, s ? s : "/");
however, bozostrdup() may reference request->hr_file.

- adjust the directory indexing again:
- don't include "index.html" in html headers
- additional escaping of names
- re-add top/bottom borders
- adds an aquamarine table header
- Zebra-stripes table rows using CSS instead of code

At present, aarch64 doesn't actually offer OABI compatibility. Also
note that this provides OABI vs. EABI compatibility for 32-bit ARM
ports. Addresses the remainder of PR misc/48968.
1. "avail_start" and "start" were different, resulting in unreachable code in
uvm_page_physunload(), where the condition check "avail_start" < "end" fails.
The test has been fixed by setting "avail_start" and "start" to the same value.
2. If "start" is the address with end address being "start + 2", we can
unplug twice, the first paddr_t would be "start" and the second one would be
"start + 1". Modified the ATF_CHECK_EQ() to reflect these changes.

There is a condition check which failed for VM_PHYSSEG_MAX == 2 (not for
1 or 3 and above), in case of 2, pgs == slab + npages1 + npages3, so we
need to change ">" check to ">=" check.
