Extentions (clang already defines them):
__ARM_PCS is defined to 1 if the default procedure calling standard for
the translation unit conforms to the "base PCS" defined in [AAPCS].
__ARM_PCS_VFP is defined to 1 if the default is to pass floating-point
parameters in hardware floating-point registers using the "VFP variant PCS"
defined in [AAPCS].
gcc: avoid generating negative values to DW_AT_byte_size.
There is a bug in gcc (GCC/35998) where dwarf reports
sizes of unsigned -1 (0xffffffff).
On NetBSD this generated a faulty CTF entry which then
caused a segfault in ctfmerge. The issue was worked
around in NetBSD's Dtrace but since the issue originated
in gcc, it seems reasonable to fix it here.
Thanks to Christoph Mallon for pointing out a correct fix.
it and the OS has enabled XGETBV for application use.
It might need to also check XCR0[2] (having executed XGETBV) to check that
the kernel actually supports saving the YMM registers, but I suspect the
kernel might defer setting that until the first fault.

the TOOLDIR version of libnbcompat, associated include files,
and associated defs.mk file, instead of the version from the
.OBJDIR of src/tools/compat. This should fix PR 47188.
GCC/i386 has code to lower the required alignment for long long to 32bit
as the CPU doesn't need more. It is also using the same mode for setting
up the MMX registers and in turn, the stack slots reserved for spilling
require 32bit alignment. The actual vector types used keep the original
64bit alignment, so when the compiler wants to spill a MMX register, it
hits an assertion. Fix this by using the vector type as raw type for MMX
registers.

This consists of two parts:
- for NetBSD/i386 and NetBSD/AMD64 with -m32, use a default stack
alignment of 23bit as specified by the ABI
- ensure that double and long long variables on the stack are by default
only aligned to 32bit, if there is nothing else in the function
needing a larger stack alignment
The combination ensures that SSE variables on the stack trigger the
realignment logic, but just using double or long long doesn't.
archs - gcc 4.5 is not able to properly track alignment and backporting
the fix from 4.6/4.7 is not feasible (according to upstream).
See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46483 for details.

instead, which is the main thread instead of the currently executing thread
which is not what we want, since we've been running and nother thread might
have just started.
1. thread_self() returns a pointer, not an unsigned integer
2. Add NetBSD to Apple and FreeBSD defines
3. Add _NETBSD_SOURCE where needed
4. Add an extra define BEGIN_PROTECTV for void functions to avoid return
free(); where free is void.
5. Avoid weak symbol hacks to determine if we are threaded or not. We
have a threaded copy of the library, why bother?
6. change __attribute -> __attribute__ since the former is not covered by
our cdefs.h
causes gcc indigestion (internal compiler error) for all m68k ports.
mrg@ says this will do for now, and committing to this generated-
by-mknative file is ok.
The problem has to do with the threaded initialization.
After we take the first breakpoint and we enter single step mode,
we set trap_expected = 1 in the thread_info structure for main <pid,0,0>.
After the threads initialize, the main thread becomes <pid,1,0>, and so
we get a new thread_info struct with trap_expected = 0, and so we break.

relocations in non-PIC mode.

- struct vfs_quotactl_args -> struct quotactl_args
- add sys/stdint.h to sys/quotactl.h for clean userland build
- install sys/quotactl.h in /usr/include
- update set lists for same
- add new marshalling code in libquota
- add new unmarshalling code in vfs_syscalls.c
- discard proplib interpreter code in vfs_quotactl.c
- add dispatching code for the 14 quotactl ops in vfs_quotactl.c
- mark the proplib quotactl syscall obsolete
- add a new syscall number for the new quotactl syscall
- change the name of the syscall to __quotactl()
- remove the decl of the old quotactl from quota/quotaprop.h
- add a decl of the new quotactl to sys/quotactl.h
- update the libc build
- update ktruss
- remove proplib marshalling code from libquota
- update copy of syscall table in gdb ppc sources
- hack rumphijack to accomodate new quotactl name (as I recall,
pooka wanted such a name change to simplify something, but I
don't really see what/how)
This change appears to require a kernel version bump for rumpish
reasons.
