| | | | | | | | | Do not pollute libraries with its own implementation of __aeabi_unwind_cpp_pr1 code. Just add it to uclibc_nonshared.a archive and share it.

* libc: allow to backtrace out of abort callCarmelo Amoroso2012-01-131-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Build raise and abort function with dwarf2 info by using -fasynchronous-unwind-tables to make backtrace() working across a call to abort. A scenario where it could be useful is within a signal handler that wants to dump a backtrace when catching some signal (i.e SIGABRT). Without having abort & raise built with DWARF2 information, it is not possible for the libgcc stack unwinder to walk through the call stack out of the abort/raise function.

* nptl:arm: add a wrapper for .cfi_sections pseudo-opsCarmelo Amoroso2011-02-252-2/+2
| | | | | | | | | | | | | | | | 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.

However, it looks the reason for upstream not using PLT calls is that ebx gets clobbered. So we need to reload it.

* 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 Gordeev2010-10-271-2/+2
| | | | | | | | | | | | | | | 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.
