2009-11-22Revert "libc: add hidden calls to pthread cleanup funcs"Austin Foxley
This reverts commit e0ac4efbdb498319f03a2a95d75d061ab6c68491. Was causing segfaults on every pthread linked executable Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2009-11-22remove wait callbacks for non-cancelation funcsBernhard Reutner-Fischer
No need to install a cancellation handler, these are no cancellation point. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>

2009-11-09libc: add hidden calls to pthread cleanup funcsMike Frysinger
A lot of libc code calls the pthread cleanup funcs implicitly (for stdio) which currently goes through the PLT. Since we already have forwarding symbols for these funcs, it's safe to declare the internal libc usage hidden as a loaded libpthread will have the real symbols found. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2009-11-09make the sem_open changes actually compileAustin Foxley
__gen_tempname now needs to not be hidden so libpthread can get at it Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2009-11-09Unbreak sem_open when UCLIBC_SUSV3_LEGACY is not definedMikhail Gusarov
sem_open uses mktemp to create temporary file. Reimplement it using __gen_tmpname, removing ugly while(1) loop. As a side-effect remove the potential source of EAGAIN errors. Signed-off-by: Mikhail Gusarov <dottedmag@dottedmag.net> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>

2009-09-19sigwait: remove __sigwait and __GI_sigwait symbols - they are unusedDenys Vlasenko
sigwait is not called from any uclibc function, so "hidden symbol" trick is not needed on it. __sigwait also is never used, and it's not clear why it even existed. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2009-07-26linuxthreads.old: define pthread_yield to sched_yieldMike Frysinger
The pthread_yield() function in linuxthreads does the same thing as the standardized sched_yield() function, so add a simple define for it to make porting GNU apps easier. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-21linuxthreads.old: fix crash in debug codeMike Frysinger
If pthread_join() is called and there is nothing to join, then the debug code will attempt to dereference a NULL pointer. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-07-20linuxthreads.old: extend workaround for asm rename warningsMike Frysinger
The libc_pthread_init.c needs the include workaround like forward.c, and forward.c needs more includes now. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Signed-off-by: Ron Lee <ron@debian.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-05Check #if feature test macros are defined where they may not beRon
Once again all of these reduce the noise from gcc-4.4. Replaces a few more (USE_TLS && HAVE___THREAD) with USE___THREAD while we need to mess with them for this anyhow. Signed-off-by: Ron Lee <ron@debian.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-05Provide token prototypes for functions that are external but have no headerRon
This cuts down on a lot of noise from gcc-4.4 Signed-off-by: Ron Lee <ron@debian.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-07-05Add noreturn attributes to some functions that won't ever do soRon
usage() is also made static in answer to warnings about no prototype. In __pthread_manager_event() we also have to drop the return statement, else gcc will in turn complain about a non-returning function having one.

2009-05-21fix compilation of linuxthreads for sparc64Austin Foxley
Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2009-04-09The attached patches fixes the problems found bringing up uclibc on coldfire Khem Raj
M5485 processor 1. Disable mmap2() if we're compiling for coldfire and fall back to mmap(). It seems to map a different file area on a 2.6.25 linux kernel. 2. Uses pc-relative addresing[1], computes ADDR_ALIGN, PAGE_ALIGN and OFFSET_ALIGN relatively to _dl_pagesize[3]. On coldfire/M5485 _dl_pagesize is 0x2000.

2009-03-12add linuxthreads support for arm. By Will Newton (will.newton AT gmail.com)Denis Vlasenko
2009-03-12linuxthreads fixes from Will Newton (will.newton AT gmail.com):Denis Vlasenko
* share Sys V semaphores in order to get appropriate SEM_UNDO semantics. * correct guardaddr in pthread_free() for TLS case * move spinlock unlocking before restart() * When exit was called from a signal handler, the restart from the manager processing the exit request instead restarted the thread in pthread_cond_timedwait. (see http://sources.redhat.com/ml/libc-ports/2006-05/msg00000.html)
