+
+ * regcache.c (registers_changed, registers_fetched): Use
+ ARCH_NUM_REGS directly, eliminating an unnecessary variable.
+
+ This change adds pseudo-register capability to GDB.
+ Pseudo-registers are handled like registers, but they
+ don't come from or live on the target. They may be
+ aliases for an existing register, or they may be computed.
+ * defs.h (NUM_PSEUDO_REGISTERS): Define default of zero.
+ (ARCH_FETCH_PSEUDO_REGISTERS): Define default of no-op.
+ (ARCH_STORE_PSEUDO_REGISTERS): Define default of no-op.
+ # regcache.c (registers_changed): Mark pseudo-registers
+ invalid, as well as real registers.
+ (registers_fetched): Do not mark pseudo-registers as fetched
+ at the same time as other (real) registers.
+ (read_register_bytes): Fetch pseudo-registers (if any) from
+ the target architecture module instead of from the target.
+ (read_register_gen): Ditto.
+ (read_register): Ditto.
+ (write_register_bytes): Store pseudo-registers (if any) to
+ the target architecture module instead of to the target.
+ (write_register_gen): Ditto.
+ (write_register): Ditto.
+ (build_regcache): Allocate enough register_valid space for
+ pseudo-registers as well as normal (real) ones.
+ * parse.c (target_map_name_to_register): Include pseudo-regs.

+ 32 bits.
+ (_initialize_remote_mips): Add ``set mask-address'' command.
+
+ * mips-tdep.c (_initialize_mips_tdep): Replace "set mask-address"

+ 16 byte boundary. Align allocated argument space using
+ MIPS_STACK_ARGSIZE. Reserve space on stack for the struct return
