* nptl: fix Unwind_Resume PLT callsTimo Teräs2010-12-092-7/+15
| | | | | | | | | | My change a49b3a18e463cbe8c94c41501e386e7f4c61609e fixed two Unwind_Resume calls to go via PLT to avoid text relocations for PIC builds. However, it looks the reason for upstream not using PLT calls is that ebx gets clobbered. So we need to reload it.

* libc_sh: add __tls_get_addr to static libc (SH)Filippo Arcidiacono2010-12-012-1/+32
| | | | | | | | | | Add __tls_get_addr function to static libc allowing to handle local dynamic TLS access model. On SH, linker optimizations are not required, so __tls_get_addr can be called even in statically linked binaries.

Indeed recent updates into buildsys managed to filter-out generic implementation when arch specific one is defined, so duplicated symbols into the libc.a In the meanwhile, do a minor fix into mips version not using relative path to include <generic/libc-tls.c> Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
* libc_tls: Do not include generic libc-tls from arch specific implementationCarmelo Amoroso2010-11-292-2/+0
| | | | | | | | | | | libpthread/nptl/sysdeps/generic/libc-tls.c is built as well, so it does not need that arch specific version of libc-tls.c (MIPS and ALPHA) includes it. The arch libc-tls.s is aimed to provide the implementation of __tls_get_addr for the static libc.a, because on these archs the linker relaxations are not required and it could be possible to have local-dynamic access models in static libraries as well.

* ntpl: fix static linking by not leaking SSP_ALL_CFLAGSNatanael Copa2010-11-1115-16/+0
| | | | | | | | | | | | | | | The SSP_ALL_CFLAGS in nptl arch CFLAGS leaks out and forces things like dl-support.c, brk.c, sbrk.c memcpy, etc to be built with -fstack-protector-all. This is bad when linking statically since initializing TLS will call those functions before SSP is initialized. The libpthread itself will still be built with -fstack-protector-all due to CFLAGS-nptl has SSP_ALL_CFLAGS in libpthread/nptl/Makefile.in Thanks to Timo Teras for helping with this.

* mips: fix errno setting after syscallAlexander Gordeev2010-10-272-3/+4
| | | | | | | | | | | | | | | If there was an error during syscall then after it's completion a3 register holds a non-zero value and v0 holds an actual error code which should be saved in errno. This can be achieved by calling __syscall_error with the value from v0 as a parameter. So this value should be stored in a0, but the appropriate assembly instructions are missing. Fixed this now by adding "move a0, v0". I think it was once fixed by 58c5f8ba4cdf62342d05a546d15404cbbb3c4e07 but then something went wrong. Again...

* nptl: fix calling convention for __pthread_mutex_cond_lockTimo Teräs2010-08-172-3/+10
| | | | | | | | | | | | | | | | | | The assembly versions of pthread_cond_wait calls __pthread_mutex_cond_lock and __pthread_mutex_cond_lock_adjust using internal calling convention (which differs from default calling convention at least on x86). Thus these two functions must be defined with internal_function or the call sequence goes wrong. __pthread_mutex_cond_lock resides in sysdeps/unix/sysv/linux/pthread_mutex_cond_lock.c, but it does evil macro definitions and includes pthread_mutex_lock.c, so we need to add some extra kludge to pthread_mutex_lock.c to get the prototypes correctly.
