2010-12-01libc_sh: add __tls_get_addr to static libc (SH)Filippo Arcidiacono
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.

2010-12-01Revert "libc_tls: Do not include generic libc-tls from arch specific ↵Carmelo Amoroso
implementation" This reverts commit 0c468129356f5ce6780e7369c271d74631ae03ba. 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>
2010-11-29libc_tls: Do not include generic libc-tls from arch specific implementationCarmelo Amoroso
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.

2010-11-11ntpl: fix static linking by not leaking SSP_ALL_CFLAGSNatanael Copa
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.

2010-10-27mips: fix errno setting after syscallAlexander Gordeev
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...

2010-08-17nptl: fix calling convention for __pthread_mutex_cond_lockTimo Teräs
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.
