2015-08-18xtensa: fix _Unwind_GetCFAMax Filippov1-1/+1
Returning context->cfa in _Unwind_GetCFA makes CFA point one stack frame higher than what was actually used by code at context->ra. This results in invalid CFA value in signal frames and premature unwinding completion in forced unwinding used by uClibc NPTL thread cancellation. Returning context->sp from _Unwind_GetCFA makes all CFA values valid and matching code that used them. 2015-08-18 Max Filippov <jcmvbkbc@gmail.com> libgcc/ * config/xtensa/unwind-dw2-xtensa.c (_Unwind_GetCFA): Return context->sp instead of context->cfa.

2015-04-17Hide __cpu_indicator_init/__cpu_model from linkerH.J. Lu2-2/+7
We shouldn't call external function, __cpu_indicator_init, while an object is being relocated since its .got.plt section hasn't been updated. It works for non-PIE since no update on .got.plt section is required. This patch creates libgcc.so as a linker script, hides __cpu_indicator_init and __cpu_model in libgcc.so.1 from linker, forces linker to resolve __cpu_indicator_init and __cpu_model to their hidden definitions in libgcc.a while providing backward binary compatibility. gcc/testsuite/ PR target/65612 * g++.dg/ext/mv18.C: New test. * g++.dg/ext/mv19.C: Likewise. * g++.dg/ext/mv20.C: Likewise. * g++.dg/ext/mv21.C: Likewise. * g++.dg/ext/mv22.C: Likewise. * g++.dg/ext/mv23.C: Likewise. libgcc/ PR target/65612 * config.host (tmake_file): Add t-slibgcc-libgcc for Linux/x86. * config/i386/cpuinfo.c (__cpu_model): Initialize.
