postreload-gcse.c (reg_changed_after_insn_p): New function.
gcc/
* postreload-gcse.c (reg_changed_after_insn_p): New function.
(oprs_unchanged_p): Use it to check all registers in a REG.
(record_opr_changes): Look for clobbers in CALL_INSN_FUNCTION_USAGE.
(reg_set_between_after_reload_p): Delete.
(reg_used_between_after_reload_p): Likewise.
(reg_set_or_used_since_bb_start): Likewise.
(eliminate_partially_redundant_load): Use reg_changed_after_insn_p
and reg_used_between_p instead of reg_set_or_used_since_bb_start.
Use reg_set_between_p instead of reg_set_between_after_reload_p.
* rtlanal.c (reg_set_p): Check whether REG overlaps
regs_invalidated_by_call, rather than just checking the
membership of REGNO (REG).
