493d341048 various build fixes for gcc 4.5. from chuq. XXX i'm not sure all of 
these work properly wtf pointer aliasing, but there are no casts at
least...

the lib/libpuffs/puffs_priv.h is definately a real bug fix.

a2925d9cef __udivdi3 isn't included in sparc compat libc on sparc64, so use 
ARCHSUBDIR instead of MACHINE_ARCH for checking whether to include
quad/Makefile.inc.

This fixes undefined symbol __udivdi3 in /libexec/ld.elf_so-sparc
on sparc64 which is the cause of failure of hello32 test in
toolchain/cc/t_hello.

bdd01b22a1 Functions that return a struct or union, must set %eax to the value

f3fc9a4693 Use excb before and after the mt_fpcr/mf_fpcr instructions as specified 
in the alpha ARM 4.7.8.1 (Accessing the FPCR):

	Because Alpha floating-point hardware can overlap the execution of
	a number of floating-point instructions, accessing the FPCR must
	be synchronized with other floating-point instructions. An EXCB
	instruction must be issued both prior to and after accessing the
	FPCR to ensure that the FPCR access is synchronized with the
	execution of previous and subsequent floating-point instructions;
	otherwise synchronization is not ensured.

Use unions to convert between double and uint64_t to avoid casting.

Do not bother to save volatile (caller saved) global registers.

d21307a5d2 Fix offsets used in the assembly code to save global registers into a 
jmp_buf, add a compile time assert to catch this kind of divergence
in the C code.
Move the fixed "%npc = %pc + 4" computation to longjmp, this frees
the sigcontext sc_npc value. Use this space to save the savemask
for siglongjmp (we have run out of space behind the globals).
Fixes the tests/lib/libc/setjmp/t_threadjmp tests, and also hopefully
fixes PR port-sparc64/44902.

2d8f83e77b Fix various vis/unvis issues: 
- no need for all the weak symbols
- define a new _VIS_END flag for UNVIS_END so that there are no collisions
  between and vis and unvis flags.
- add bound versions of the vis and unvis functions that take the length of
  the destination buffer. Unlike the OpenBSD ones they return -1 or NULL if
  the buffer is not large enough, instead of silently truncating.

aad599979d Add TLS support infrastructure. For dynamic binaries, ld.elf_so exports 
_rtld_tls_allocate and _rtld_tls_free. libpthread uses this functions to
setup the thread private area of all new threads. ld.elf_so is
responsible for setting up the private area for the initial thread.
Similar functions are called from _libc_init for static binaries, using
dl_iterate_phdr to access the ELF Program Header.

Add test cases to exercise the different TLS storage models. Test cases
are compiled and installed on all platforms, but are skipped on
platforms not marked for TLS support.

This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.

It is inspired by the TLS support in FreeBSD by Doug Rabson and the
clean ups of the DragonFly port of the original FreeBSD modifications.

5c3ccd6eba Pass down ELF Auxillary Vectors for static NetBSD binaries too. 
Rename __libc_init to _libc_init and call it explicitly from CSU code.
This enforces the constructor run order for newly linked programs.
Keep it as constructor with run-once semantic for binary compatibility.
Implement dl_iterate_phdr for statically linked programs.

063f96f3c2 merge the bouyer-quota2 branch. This adds a new on-disk format 
to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.

See http://mail-index.netbsd.org/tech-kern/2011/02/19/msg010025.html
for details.

49f1dcc8e5 While we use hardware (for float and double), but cooperate with softfloat 
(to do long double), we need to not only handle the hardware exception
mask and cummulated flags, but also update/query the softfloat variables.
Since this may go away sometime (to make us psABI compliant), ifdef it
properly.
