* config/mips/tm-mips.h, config/mips/tm-irix3.h,
config/mips/tm-irix6.h (NUM_REGS): Delete.
* mips-tdep.c (mips_gdbarch_init): Call set_gdbarch_num_regs().
(temp_saved_regs): Declare as a pointer rather than an array.
(mips32_heuristic_proc_desc, heuristic_proc_desc): Make sure
that ``temp_saved_regs'' has storage allocated to it and that
it's the correct size.

* defs.h (init_last_source_visited): New prototype. * defs.h (init_last_source_visited): New prototype.
