* remove wait callbacks for non-cancelation funcsBernhard Reutner-Fischer2009-11-174-24/+0
| | | | | | | No need to install a cancellation handler, these are no cancellation point. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

* libc: add hidden calls to pthread cleanup funcsMike Frysinger2009-11-092-0/+4
| | | | | | | | | | 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.

* make the sem_open changes actually compileAustin Foxley2009-11-091-1/+1
| | | | | | __gen_tempname now needs to not be hidden so libpthread can get at it Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
* Unbreak sem_open when UCLIBC_SUSV3_LEGACY is not definedMikhail Gusarov2009-11-091-32/+5
| | | | | | | | | 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.

| | | | | | | | | 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> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>

* linuxthreads.old: define pthread_yield to sched_yieldMike Frysinger2009-08-191-0/+5
| | | | | | | | | 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> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>

| | | | | | | | | | 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.

* Add noreturn attributes to some functions that won't ever do soRon2009-07-091-2/+2
| | | | | | | | | | 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.

* sh_nptl: Fix pthread_barrier_wait epilog to properly restore r9Carmelo Amoroso2009-07-022-3/+3
| | | | | | | | | | | | | | In the pthread_barrier_wait function's epilog implementation do not use the macro ret (that is defined as rts; nop) to correctly execute in the delay slot the instruction "mov.l @r15+, r9" that will restore the r9 register to the previous value saved on the stack and as side effect will restore the stack pointer register back to the correct value. Same fix is applied to __lll_mutex_lock_wait, even if in the delay slot we have actually a nop, so using the macro would be safe here.

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.
