* 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.
