* 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.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*.
