2015-09-28Update soft-fp from glibc.Joseph Myers1-0/+84
This patch updates the soft-fp code in libgcc from glibc. There are no changes here of significance to the use of soft-fp in GCC (and so no testsuite additions); it's simply an update to bring in the latest soft-fp version (which will also hopefully go into Linux 4.4 to replace the 15-year-old copy currently in Linux).

2015-08-18xtensa: fix _Unwind_GetCFAMax Filippov1-0/+5
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.
