flow.c (life_analysis_1): Do not clobber regs_ever_live after reload.
* flow.c (life_analysis_1): Do not clobber regs_ever_live after
reload. Never perform rescans of the insn chain after reload.
(propagate_block): Do not delete insn or create new autoinc addressing
modes after reload.
* jump.c (jump_optimize): Unconditionally use the code that was
previously conditional on PRESERVE_DEATH_INFO_REGNO_P.
* reload1.c (reload): When reloading is finished, delete all
REG_DEAD and REG_UNUSED notes.
(emit_reload_insns): Delete all code that was conditional on
PRESERVE_DEATH_INFO_REGNO_P.
(no_longer_dead_regs): Delete variable.
(reload_cse_delete_death_notes): Delete function.
(reload_cse_no_longer_dead): Delete function.
(reload_cse_regs_1): Delete all code to handle deletion of death
notes.
(reload_cse_noop_set_p): Likewise.

* reorg.c (used_spill_regs): Delete declaration.
(max_label_num_after_reload): Delete declaration.
(find_dead_or_set_registers): Don't assume that spill regs are
dead at a CODE_LABEL.
* rtlanal.c (dead_or_set_regno_p): Death notes are always accurate,
even after reload.

* toplev.c (max_label_num_after_reload): Delete variable.
(rest_of_compilation): Don't set max_label_num_after_reload.
Call life_analysis after reload_cse_regs if optimizing.
* config/gmicro/gmicro.h: Delete comment referring to
PRESERVE_DEATH_INFO_REGNO_P.
