The xtensa port uses __xtensa_libgcc_window_spill in libgcc to implement __builtin_frame_address. This symbol is local/hidden in libgcc. This is not a problem when linking against static libgcc. But g++ defaults to -shared-libgcc, thus breaking link against C++ shared libraries that are using __builtin_frame_address as follows: ld: test: hidden symbol `__xtensa_libgcc_window_spill' in .../libgcc.a(lib2funcs.o) is referenced by DSO Add upstream patches that make libgcc_s.so a linker script that links in unresolved symbols from the static libgcc, similar to the ARM and PowerPC ports.
