caller-save.c (insert_one_insn): Returns struct insn_chain *.
* caller-save.c (insert_one_insn): Returns struct insn_chain *.
Handle live_throughout / dead_or_set instead of live_before /
live_after.
(save_call_clobbered_regs): Get register livenessinformation from
chain->live_throughout.
(add_stored_regs): New function.
(insert_restore, insert_save): Add restored / saved registers to
dead_or_set.
* global.c (reg_dies): New parameter chain.
(reg_becomes_live): Third parameter is regs_set now.
Changed all callers.
(reg_dies): New parameter chain. Changed all callers.
(build_insn_chain): Set live_throughout instead of
live_before / live_after.
* reload.h (struct insn_chain): Replace members live_before /
live_after with live_throughout / dead_or_set.
* reload1.c (new_insn_chain): Handle live_throughout / dead_or_set
instead of live_before / live_after.
(maybe_fix_stack_asms, find_reload_regs, finish_spills): Likewise.
(order_regs_for_reload, find_reg, finish_spills): Likewise.
(choose_reload_regs_init): Likewise.
* stupid.c (current_chain, find_clobbered_regs): Delete.
(stupid_life_analysis): Set chain->live_throughout chain->dead_or_set
instead of chain->live_before / chain->live_after.
(mark_hard_ref): New function.
(stupid_mark_refs): Call mark_hard_ref. Clear chain->live_throughout.
