gcc : ChangeLog basic-block.h except.c flow.c jump.c
output.h reg-stack.c sibcall.c toplev.c
Log message:
* flow.c (merge_blocks_move_successor_nojumps): Do not crash
when fallthru edge is present.
(mege_blocks): Handle case where creation of jump insn
is required.
* basic-block.h (CLEANUP_EXPENSIVE, CLEANUP_CROSSJUMP,
CLEANUP_POST_REGSTACK): New constants.
* except.c (finish_eh_generation): Update call of cleanup_cfg,
* jump.c (rtx_renumbered_equal_p): Handle 't' fields.
* output.h (cleanup_cfg): Update prototype.
* reg-stack.c (reg_to_stack): Use cleanup_cfg instead of jump_optimize
* sibcall.c (optimize_sibling_and_tail_recursive_call): Update
cleanup_cfg call; kill missleading comment.
* toplev.c (rest_of_compilation): Update all cleanup_cfg calls.
* flow.c (merge_blocks, try_optimize_cfg, cleanup_cfg): Accept mode
parameter; control optimizations performed using it.
(flow_find_cross_jump, outgoing_edges_match, try_crossjump_to_edge,
try_crossjump_bb): New functions.
