rtlanal.c (label_is_jump_target_p): Return true for a matching REG_LABEL_TARGET.
* rtlanal.c (label_is_jump_target_p): Return true for a matching
REG_LABEL_TARGET.
* reorg.c (fill_slots_from_thread): Correct last change to use
NULL_RTX, not NULL. Outside of REG_NOTES loop, increase and
decrease LABEL_NUSES for JUMP_LABEL (trial), not XEXP (note, 0).
* jump.c (mark_jump_label_1): Add comment for last change
regarding JUMP_LABEL setting.
* gcse.c (add_label_notes): Remove conditional that the label is
mentioned in insn before adding regnote.
* sched-rgn.c (is_cfg_nonregular): Don't return 1 for a
single_set insn only feeding a label to a jump through a
register that dies there.
