Joel,

2004-07-22 Joel Brobecker <brobecker@gnat.com>

        * mips-tdep.c (mips_mdebug_frame_cache): Minor reformatting.
        (set_saved_reg_info): New function.
        (mips32_heuristic_proc_desc): Compute the procedure descriptor
        PROC_REG_OFFSET.

It's time to cut our losses and split the mdebug and heuristic cases. Lets work through this change after I've done that.

In the mean time, can I encourage you to look at the s390 and it's stub-unwinder - the MIPS desperatly needs one of these (and it is something that can be wipped up in isolation). To see where its needed do a STEPI into shlib trampoline code.

Andrew
