New OPTIMIZED_OUT_ERROR error code.
In order to catch <optimized out> errors like we catch <unavailable> errors, this adds a new OPTIMIZED_OUT_ERROR error code, and throws it in various places. gdb/ChangeLog 2013-12-06 Andrew Burgess <aburgess@broadcom.com> Pedro Alves <palves@redhat.com> * exceptions.h (errors): Add OPTIMIZED_OUT_ERROR. * dwarf2loc.c (write_pieced_value): Throw OPTIMIZED_OUT_ERROR. * frame.c (frame_unwind_register): Throw OPTIMIZED_OUT_ERROR. * spu-tdep.c (spu_software_single_step): Throw OPTIMIZED_OUT_ERROR. * valops.c (value_assign): Throw OPTIMIZED_OUT_ERROR.
