ad ae87f94d1d Bump libc/libpthread minor for thr_curcpu()/pthread_curcpu_np(). 2007-11-27 21:06:41 +00:00
ad 4084ca7f3f Add thr_curcpu(), pthread_curcpu_np(). 2007-11-27 20:58:26 +00:00
tnozaki 7e1ba00ce8 more PR/36938, restore internal-state if mbtowc() throw EILSEQ. 
patch provided by Shiozaki-san, thanks.

dsl d8e8042c1c Add a note about the difficulty of actually looking at the return value 
of __syscall() caused by ABIs (eg sparc) that don't pass the low bits of
a 64 bit result in the same register as a 32 bit result.

uebayasi 2b37ebddcf KNF; no variable name in function prototype. 2007-11-23 12:39:15 +00:00
dsl 3ba44b945b Reorder the code for i386 and amd64 syscall stubs so that the 'jc' on error 
is a forwards jump instead of a backwards jump that a P4 will mispredect (and
probably immediatly get a cache-line miss due to the way the code gets
aligned).
 2007-11-23 07:36:05 +00:00
dsl b0b7248d92 Change all the syscall C 'glue' functions (most of which just add in an 
extra argument to ensure that 'off_t' parameters are even numbered
parameters for stack alignment reasons on 32 bit systems) to use a normal
'syscall' wrapper for __foo instead of using __syscall(SYS_foo, ... ).
This saves all the faffing needed to get a 32bit return value on sparc.
Auto-generate the extra syscall wrappers.
Move swapon.c into the correct list (swapon() uses swapctl()).
This probably means there are very few users of syscall() and __syscall() left.

tnozaki fca38949e4 fix lib/37290 
- don't call abort(3) when there's no suitable charset found.
- use iso-8859-1(or INIT1 if specified) for C1 control char.

skrll 4f3467d61e Remove unused include. 
Fix unwind info with S/ENTRY/LEAF_&/
 2007-11-18 14:11:25 +00:00
skrll 8ed2bd6ec6 Generate correct unwind info for syscall stubs by using LEAF_ENTRY instead 
of ENTRY(foo,0) so that gdb can backtrace through the stubs.

drochner 095b25e7dd Add pthread_equal() to libc stubs; this makes a lot of sense for 
threadsafe libraries implementing own locking functions.
Ride on yesterday's minor version bumps.

ad 3c776c8aa6 Bump libc minor for _lwp_ctl, libpthread constructor changes. 2007-11-13 17:13:14 +00:00
ad 46f5cd4fb9 - Make it pass lint. 
- Add RCSID.
 2007-11-13 15:33:55 +00:00
ad ec4d182d4a - stack_protector.c doesn't really belong under sys/. Add a new directory 
for misc support routines and put it there.
- Add a libc constructor. Use this to initialize threading and the
  stack protector stuff. libpthread cannot be initialized safely using
  its own constructor because libc and libpthread are deeply intertwined.

he 3b9b3c5341 We now need <sys/lwpctl.h> included in order to lint LintSysNormal.c. 2007-11-13 09:07:33 +00:00
ad b668a9a05f Add _lwp_ctl() system call: provides a bidirectional, per-LWP communication 
area between processes and the kernel.
 2007-11-12 23:11:58 +00:00
ad 51a2159851 Don't unconditionally clear the direction flag. The ABI says it must always 
be clear when making a function call, and 'cld' takes about 50 clock cyles
on the P4.

christos 0405bf4cb9 always compile getopt_long. some ifdef reduction. more to come. 2007-11-09 03:29:20 +00:00
martin 4cdfe9d3ee When creating unsigned int results, do not distinguish positive versus 
negative overflow.
 2007-11-08 21:31:04 +00:00
martin 5265977a9e When converting long double values to integer types, explicitly use the 
"round to zero" variants of the softfloat conversion functions.
Add a variant to convert long double to unsigned long - the "to long"
variant checked for overflows that do not apply to unsigned results.
This fixes the regress/lib/libc/convfp tests for sparc64.

ad bdd61de26b Add _lwp_setname/_lwp_getname to libc. 2007-11-07 00:52:25 +00:00
christos b3b90d7485 Revert previous. This mess of ifdefs needs to be killed. 2007-11-06 22:08:51 +00:00
martin c607cb216f Mark the characters between 0x80 and 0xff as 1 cell wide, if compiled 
with ALL_80_TO_FF_SW1 defined. This is not correct in the general case,
but helps in certain restricted environments where nothing but the
default locale is available and we know what we do(tm).
 2007-11-06 19:24:19 +00:00
christos 9df03145fa move the test to replace getopt higher up, before we need to include anything. 2007-11-06 19:13:16 +00:00
dsl bd8185f2eb syscall() has to be implemented in the kernel - so is a normal system call here.This has always been broken, so I suspect everything is using __syscall(). 2007-11-05 20:30:07 +00:00
pooka 2592930cfe remember to bump date 2007-11-04 21:36:59 +00:00
pooka 057838d510 libc errlist uses "Block device required" for ENOTBLK, so display 
that also here.

skrll 29353f93e2 Build a local copy of exit that doesn't call __cxa_finalize. It's not 
needed and drags in a lot of libc via free.

skrll f1273d89a6 Set up the tail of the instruction address queue so that 
we don't have to rely on luck for swapcontext(3) to work.

This fixes a problem pointed out to me by Chuck Silvers.

simonb e19457f411 Add a reference to RFC 2783. Requested by joerg@ 2007-10-22 05:35:37 +00:00
simonb 46de085339 Revert the CSE parts of the previous change. "run" is calculated with 
a different value for "pageind" each time through the loop, so we can't
precalculate it.

Fixes awk core dump issues on powerpc 405.

ad 3465d8db6f Add defs for hppa. From he@. 2007-10-09 00:59:52 +00:00
uwe a34b3f871d In handwritten asm use -fPIC code instead of -fpic, our libc has grown 
large enough for GOT to be larger than 8k.

While here kill redundant PIC ifdefs in setjmp.S - sparc "call"
instruction is piccy by itself.

he 7ed9cc8edd On sparc64, both __sparc__ and __sparc64__ is defined. Avoid redefinition 
of size constants for sparc64.

This code still produces many, many lint warnings due to "may loose accuracy"
when mixing long/int, and also warnings related to <<.
