2015-08-18xtensa: fix _Unwind_GetCFAMax Filippov2-1/+6
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. From-SVN: r226964

2015-08-18xtensa: reimplement register spillingMax Filippov2-7/+30
Spilling windowed registers in userspace is much easier, more portable, less error-prone and equally effective as in kernel. Now that register spilling syscall is considered obsolete in the xtensa linux kernel replace it with CALL12 followed by series of ENTRY in libgcc. 2015-08-18 Max Filippov <jcmvbkbc@gmail.com> libgcc/ * config/xtensa/lib2funcs.S (__xtensa_libgcc_window_spill): Use CALL12 followed by series of ENTRY to spill windowed registers.
