lukem 8346a6360d Use mkstemp() + fchmod() instead of mktemp(), since the latter 
results in linker warnings.

garbled 2ba84f0f9e Add tuned powerpc assembler written by IBM and released under a 3-clause 
BSD Lisc as part of the perflib project.
http://sourceforge.net/projects/ppcperflib/

Tested the new functions with microbenchmarks on a number of different
CPU types, and  found that most cpus either benefited greatly, or were
unaffected.  Primarily G4 CPU's were unaffected, and all others showed
speedups.  My 7044 (POWER3) went from a 70.6 to a 73.2 (thats good) in
bytebench with a complete release built with these.  Also passed
regression tests.

apb 267197ec1e For all files under src/common, as well as related man pages under 
src/lib/libc, or related headers under src/sys/sys: change u_intNN_t to
uintNN_t.
 2008-02-16 17:37:13 +00:00
apb cf01a0f8c8 C99 is no longer "very recent". Adjust a comment accordingly, and 
start using uintNN_t instead of u_intNN_t in the definitions of
sha2_{byte,word32,word64}.

nakayama da1555e6a7 Search files in arch/sparc64/atomic before arch/sparc/atomic in case of 
sparc64 32-bit kernel.

Make sparc64 32-bit kernel works again.
 2008-01-22 12:34:58 +00:00
nakayama b4ed00a22d Use __arch64__ instead of __sparc64__, since -D__sparc64__ is appended 
to build option of sparc64 32-bit kernel.

martin ececdb7913 When passing char (or unsigned char) arguments as int, assign them to a 
temporary char (resp. unsigned char) before comparing, to force truncation
to the proper domain. This makes the coresponding regression tests succeed.

mrg 97e461c633 - provide 32 bit versions of the sparc v9 atomic ops. 
- use them on sparc64 32 bit kernels.

fixes issues on 32 bit sparc64 kernels that were using sparc v8 ops.
tested by rjs@.

tsutsui 3e9910f3b8 Disable a sanity check output buffer != NULL in _STANDALONE case. 
Some kernels are loaded at address 0x0 by bootloaders and
output buffer address could be zero in such case.

Fixes "read text" errors on loading install floppy of NetBSD/news68k 4.0,
reported by KIYOHARA Takashi on port-news68k.

the includes.

joerg 22ac6fc0fb Add x86emu for in-kernel use. This is a 386 real mode emulator that can 
be used to run ROM code inside the kernel without having to setup vm86
and without having a x86 CPU at hand.

This code was originally written by SciTech and released under MIT/X11
license for XFree86. It has been refactored be less than half of the
original size, the compiled code being around a third of the former
size. The interface was changed to be a real library, e.g. no global
variables are used.
