This allows having exception cleanup code in binaries that don't register their unwind tables. 2015-08-18 Max Filippov <jcmvbkbc@gmail.com> libgcc/ * config/xtensa/t-windowed (LIB2ADDEH): Replace unwind-dw2-fde with unwind-dw2-fde-dip. From-SVN: r226963
Max Filippov committed -
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. (__xtensa_nonlocal_goto): Call __xtensa_libgcc_window_spill instead of making linux spill syscall. From-SVN: r226962
