* mipsread.c (fixup_sigtramp): Also look for _sigtramp as a real
routine (for Irix-4.x). Make many funcs static and void. * mips-tdep.c (mips-frame-chain): Clean up, simplify. * (init_extra_frame_info): Don't trash cached value of frame pointer register. This fixes backtracing through routines that use alloca(). Generally clean up declarations of functions, and use typedefs and macros to reference data structures as appropriate. * tm-irix3.h, tm-mips.h (EXTRA_FRAME_INFO): use proper type for proc_desc element.
