Divide REG_LABEL notes into REG_LABEL_OPERAND and REG_LABEL_TARGET.
...
* doc/rtl.texi (Insns): Specify when a label_ref makes a jump_insn.
Similar for what label_refs can go in the JUMP_TARGET field. Split
REG_LABEL documentation into REG_LABEL_TARGET and REG_LABEL_OPERAND.
* reload.c (find_reloads): Generate REG_LABEL_OPERAND, not
REG_LABEL when replacing an operand with a LABEL_REF for a
non-jump insn.
(subst_reloads): When replacing a LABEL_REG with a register,
instead of generating a REG_LABEL note, assert that there already
is one or that the label is a known target for the insn.
* rtlanal.c (computed_jump_p): Instead of looking for a REG_LABEL
note, check the JUMP_LABEL field. Remove "else" after return.
* reorg.c (emit_delay_sequence): Replace case for REG_LABEL with
cases for REG_LABEL_OPERAND and REG_LABEL_TARGET.
(fill_slots_from_thread): Handle both REG_LABEL_OPERAND and
REG_LABEL_TARGET notes, including the JUMP_TARGET field on JUMP_P
insns. Iterate over all notes; don't assume there's only one.
* cse.c (recorded_label_ref): Adjust comment to refer to
REG_LABEL_OPERAND.
(cse_extended_basic_block): Do LABEL_REF check for all INSN_P
insns, not just NONJUMP_INSN_P.
(check_for_label_ref): For JUMP_P insns, check that the LABEL_REF
isn't a jump target.
* jump.c (rebuild_jump_labels): Adjust head comment.
(init_label_info): Ditto. Remove REG_LABEL_OPERAND notes only;
don't reset REG_LABEL_TARGET notes, including the JUMP_LABEL field.
(mark_all_labels): For JUMP_P insns without a target, check if the
the target is noted on the previous nonjump insn.
(mark_jump_label_1): New function, guts from mark_jump_label.
<case IF_THEN_ELSE>: Handle first operand as a non-target when
marking jump target labels.
<case LABEL_REF>: Adjust for whether to generate a
REG_LABEL_TARGET or a REG_LABEL_OPERAND note.
For 'E' format rtl, iterate in descending element order.
(delete_related_insns): Handle both REG_LABEL_TARGET and
REG_LABEL_OPERAND notes. For JUMP_P insns with labels with zero
reference count, delete and fallthrough. Move finding-next-
non-deleted insn last in the function. Look at all INSN_P insns
for REG_LABEL_OPERAND notes.
(redirect_jump_2): Assert that OLABEL equals the old JUMP_LABEL of
JUMP.
* print-rtl.c (print_rtx): For JUMP_P insns and a non-NULL
JUMP_LABEL, output the INSN_UID of it.
* gcse.c: Adjust comments as appropriate to say REG_LABEL_OPERAND
and/or REG_LABEL_TARGET.
(add_label_notes): Only add REG_LABEL_OPERAND notes. Put in line
with jump.c copy by only adding notes for labels actually
referenced in the insn.
* emit-rtl.c (try_split): Don't assume only NONJUMP_INSN_P need
usage count increment; handle all INSN_P trial insns.
(emit_copy_of_insn_after): Change to not copy REG_LABEL_OPERAND
notes.
* rtl.h (struct rtx_def) <volatil>: Adjust to mention
REG_LABEL_TARGET and REG_LABEL_OPERAND.
(LABEL_REF_NONLOCAL_P): Allow REG_LABEL_TARGET and
REG_LABEL_OPERAND.
* combine.c (distribute_notes): Adjust for REG_LABEL_TARGET on
JUMP_P insns and REG_LABEL_OPERAND everywhere.
* sched-rgn.c (is_cfg_nonregular): Check for REG_LABEL_OPERANDS
on all INSN_P insns.
* reg-notes.def (LABEL_TARGET, LABEL_OPERAND): Split from LABEL.
* cfgrtl.c (delete_insn): Adjust to handle REG_LABEL_TARGET and
REG_LABEL_OPERAND notes.
* reload1.c (calculate_needs_all_insns): Adjust comments.
(set_label_offsets): Adjust to look for REG_LABEL_OPERAND notes.
* config/alpha/alpha.md (split for load of an address into a
four-insn sequence on Unicos/Mk): Adjust to use
REG_LABEL_OPERAND.
