* dwarf2loc.c (read_pieced_value): Handle get_frame_register_bytes returning that the register piece is unavailable/optimized out. (write_pieced_value): Handle get_frame_register_bytes returning that the register piece is unavailable/optimized out when doing a read-modify write of a bitfield. * findvar.c (value_from_register): Handle get_frame_register_bytes returning that the register piece is unavailable/optimized out. * frame.c (get_frame_register_bytes): New parameters `optimizedp' and `unavailablep'. Throw error on bad debug info. Use frame_register instead of frame_register_read, to fill in the new arguments. * frame.h (get_frame_register_bytes): New parameters `optimizedp' and `unavailablep'. * valops.c: (value_assign): Adjust, and handle get_frame_register_bytes failing. * spu-tdep.c: Include exceptions.h. (spu_software_single_step): Adjust, and handle get_frame_register_bytes failing. (spu_get_longjmp_target): Ditto. * gdbarch.sh (register_to_value): Change to return int. New parameters `optimizedp' and `unavailablep'. * gdbarch.h, gdbarch.c: Regenerate. * i386-tdep.c (i386_register_to_value): Adjust to new gdbarch_register_to_value interface. * i387-tdep.c (i387_register_to_value): Ditto. * i387-tdep.h (i387_register_to_value): Ditto. * alpha-tdep.c (alpha_register_to_value): Ditto. * ia64-tdep.c (ia64_register_to_value): Ditto. * m68k-tdep.c (m68k_register_to_value): Ditto. * mips-tdep.c (mips_register_to_value): Ditto. * rs6000-tdep.c (rs6000_register_to_value): Ditto.
