2011-02-25nptl:arm: add a wrapper for .cfi_sections pseudo-opsCarmelo Amoroso
ARM disables by default the support for ASM CFI directives. Anyway using an old version of binutils that does not support some new pseudo-op, the build fails as below: AS libpthread/nptl/sysdeps/unix/sysv/linux/close.oS libpthread/nptl/sysdeps/unix/sysv/linux/close.S: Assembler messages: libpthread/nptl/sysdeps/unix/sysv/linux/close.S:9: Error: unknown pseudo-op: `.cfi_sections' The problem is that the .cfi_sections pseudo should be wrapped by a macro that expands to nothing when the CFI is off.

2010-12-29sparc: fix linking issue with __syscall_error.cAustin Foxley
Finally got around to testing out latest master and noticed that some buildsystem work last summer broke shared-builds of nptl on sparc. A version of __syscall_error.c needs to be linked into both libpthread and librt Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2010-12-09nptl: fix Unwind_Resume PLT callsTimo Teräs
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.

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...

This reverts most of commit 1610762362e651f86ca284ac59a1d7ec88034e4e. Marking the symbols hidden is wrong, because libc accesses the pthreads internal symbols for internal locking. Signed-off-by: Timo Teras <timo.teras@iki.fi> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2010-04-14nptl: mark symbols with libc forwarder hiddenTimo Teräs
Add attribute_hidden to all symbols having libc forwarder. This prevents recursive self calls which would happen if libc is before libpthread in linking order: the forwarder functions would call itself via the function table, since the libpthread symbols would get overwritten with libc ones. This has not been a problem in glibc since there these symbols are marked hidden with linker version-script. Since we don't use one, we need to mark these explicitly.
