scw 3617381164 Sign-extend the return value, as required by the ABI. 2003-03-26 11:59:36 +00:00
scw 825e47398e Much rototilling to add PIC support. 2003-03-24 14:29:34 +00:00
hannken 94a50cb223 Make it work on cpus with cachelinesize < 32. 
Tested on macppc by Markus W Kilbinger.

fvdl e4189529ce No need to use movq for the small immediate values here, they'll be 
zero-extended with movl.

nathanw 4fb740b8de Implement pthread_atfork() (in libc, because the required threadlib 
stub behavior is exactly the same as the usual behavior).

simonb e32d091ca8 Fix a tyop in a comment. 2003-02-08 04:01:53 +00:00
cgd 57daa57e46 * fix handling of invalid arguments (was jumping to wrong label!) 
(found by... running the regress test!)
* clean up punctuation.
* create a proper frame for the child fn that follows the o32 calling
  conventions.  In particular, leave 4 stack slots that the child
  fn can write on, put the GP above them, and invoke .cprestore
  properly in light of the child fn arg area.  (realized it was a
  problem upon inspection, verified using the regress test compiled
  -O0.)

cgd 351f7a02f1 looks like nobody ever seriously tried the _REENTRANT version of this 
code (which, uh, seems the default for a fresh build)...  it wasn't
setting up v1 properly (the instruction to set up v1 was after the
return jump, in "reorder" code...  i.e.  after the end of the function).
That would break error returns from 64-bit syscalls (e.g. checks
in dd and who knows what else) to see if input or output are pipes.
It looks like the non-_REENTRANT version was broken (on the nathanw-sa
branch) in rev 1.9.2.1 and fixed in 1.9.2.2, but the _REENTRANT version
was never fixed, and the broken bits were merged back on to the trunk.

petrov 12784e54c3 Correct unsigned to float conversions, add license, adjust style. 2003-02-06 20:23:35 +00:00
martin 912ab5ad59 Check how the compiler expects the return value of this function 
by testing SOFTFLOATSPARC64_FOR_GCC.

Should fix PR port-sparc64/20140.

fvdl 894bd3ad9d Add ucontext glue for x86_64. 2003-01-30 02:07:30 +00:00
kleink 326194c69f Update stack frame allocation for XMM state having been added to 
mcontext_t; spotted by Frank van der Linden.
While here, also align the on-stack ucontext as required.

fvdl 75b44dbf11 Fix comment that wasn't closed because of a typo (but harmless, since followed 
by another comment).
 2003-01-26 16:22:01 +00:00

kleink 13a5336c66 Move getcontext.S from gen to sys, where it belongs. 2003-01-19 23:49:12 +00:00
scw bcbbc4f87e SH5 libc ucontext/lwp support. 
Untested for now, until I get the libpthread stuff done and
an SA userland built.
 2003-01-19 23:05:01 +00:00
matt 95b5cce5c6 Add getcontext(2) stub. 2003-01-19 19:32:39 +00:00

matt bdde89628b Cast with uintptr_t instead of u_long. 2003-01-19 08:53:36 +00:00
thorpej c7cb871964 These files are obsolete; setlogin() is now implemented in C with a 
small syscall stub.
 2003-01-18 18:28:44 +00:00
thorpej 3fdac2b8c5 Merge the nathanw_sa branch. 2003-01-18 10:52:16 +00:00
fvdl 50683c0ce9 The fast syscall path clobbers 2 registers. Which is fine for a plain 
system call, as long as the stub knows about it. However, it's bad
for sigreturn. Hence, use the old entry point for sigreturn. XXX

scw 94932a0f44 SH5 asm versions of some low-level libc routines. 
Most of these copied from libkern.

chris 0caaced5a9 Add arm asm version of memcmp, basically it's strncmp.S without the 
check for *src != 0
 2002-11-23 14:26:04 +00:00
chris 35c74e8cc5 Add an asm version of strncmp, based on strcmp. 
Add RCSID to strcmp, also use numeric label, rather than named label for
loop.

itohy 6cde54195b Assembly version of string functions. 
Originally from SHIMIZU Ryo.

rearnsha 6576c49b48 Add an assembler version of strcmp, based on example code from the ARM 
ARM.  As an example of the performance difference that this provides
a Dhrystone score on my Shark goes from 213k to 261k.

junyoung 333f362341 memcpy(3) no longer deals with overlap case; it's now forward-only. 2002-10-29 06:53:18 +00:00
junyoung 7f21deb763 Get rid of pointer wraparound check. Ok'ed by TAMURA Kent. 2002-10-29 06:35:17 +00:00
chs cab484e445 move includes to the top so that this builds in libc context too. 2002-10-29 04:40:55 +00:00

chs c04f87a03e remove setjmp/longjmp from libkern, they're not used. 2002-10-27 18:45:11 +00:00
chs c5a350ef59 use %g5 instead of %g7 (since we want to use %g7 for the cpu_info pointer 
in the kernel).  resync libc and libkern versions of this file.
