Add two pointers (saved_regs, extra_info) to struct frame_info. Introduce new macro FRAME_INIT_SAVED_REGS which replaces FRAME_FIND_SAVED_REGS. Document. Use in mn10300 and rs6000 targets. Fix side effects on ALPHA, MIPS, Z8K and SPARC targets.

the stack frame. Their offset from the previous stack frame is in fdata.gpr_offset and fdata.fpr_offset, not fdata.offset. (gdb.base/return.exp) * config/rs6000/tm-rs6000.h: Doc fixes.
1998-11-27CARP:Andrew Cagney1-7/+4
STEP_SKIPS_DELAY - add STEP_SKIPS_DELAY_P and rewrite use removing #ifdef's. NO_SINGLE_STEP - replace with SOFTWARE_SINGLE_STEP_P + SOFTWARE_SINGLE_STEP. Replace global variable one_stepped with static singlestep_breakpoints_inserted_p. Cleanup infrun.c (scary!).
