Each CODE_LABEL has a count of the times it is used
stored in the LABEL_NUSES internal field, and each JUMP_INSN
has one label that it refers to stored in the
JUMP_LABEL internal field. With this we can detect labels that
become unused because of the deletion of all the jumps that
formerly used them. The JUMP_LABEL info is sometimes looked

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.

(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.

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. * config/sh/sh.md (sh_reorg, final_prescan_insn): Ditto.

Remove "else" after return. * reorg.c (emit_delay_sequence): Replace case for REG_LABEL with cases for REG_LABEL_OPERAND and REG_LABEL_TARGET.

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.

for (note = REG_NOTES (insn); note; note = XEXP (note, 1))
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. * config/sh/sh.md (sh_reorg, final_prescan_insn): Ditto.

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_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.
