2010-12-14sh: fix memcpy saving/restoring FR12-FR15 registersGiuseppe Cavallaro
This patch fixes a bug in the memcpy that doesn't save/restore the FR12-FR15 registers (callee save registers in ST40 ABI) while copying many cache lines with FPU in single paired precision mode and by using all FPU registers (DR and XD).

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.

2010-12-08getconf: only use specs that are availableThomas Petazzoni
On older glibc (like 2.7), the _SC_V7_* symbols are not defined, making the build of current uClibc fail on Debian Lenny systems and other systems using a fairly old glibc. So we make sure to only use the specs names that are defined by the host C library.

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.

2010-11-28libc_utmp: Fix getutmp and getutmpx for x86_64Carmelo Amoroso
On x86_64, when WORDSIZE_COMPAT32 is enabled, the ut_tv field of 'struct utmp' and 'struct utmpx' are defined as two nested structs instead of being defined as 'struct timeval', so it is not possible to directly assign the two ut_tv values. This patch split the assignment by setting each fields (tv_sec, tv_usec) of the ut_tv filed separately It is als compatible with 'struct timeval' usage.

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.

2010-11-02ldouble_wrappers: remove i386-specific optimizationDenys Vlasenko
It is deemed too unsafe. Quoting Timo: If I'm building with "-fPIC -pg" it instruments all C functions with profiler stuff which is called via PLT and causes EBX reloads --> crash -fno-omit-frame-pointer is sometimes useful for profiling too --> crash Also the upcoming -fsplit-stack will be broken by this too (that might need additional uclibc support though). And I'm pretty sure there's also other similar compiler features. There's no predefined #defines in gcc for any of these. What I'm trying to say that there are *numerous* situations when the compiler can create stack frame for you without you ever knowing it. And if you want to do a tail jump, you really should be doing it from .S file where you control fully the prologue/epilogue code. (GCC naked attribute does not seem to work on x86.)
