gcc : ChangeLog.tree-ssa timevar.def tree-cfg.c
tree-dump.c tree-flow.h tree-optimize.c
tree-ssa-dom.c tree.h
Log message:
* timevar.def (TV_TREE_SSA_THREAD_JUMPS): New timevar.
* tree-dump.c (dump_files): Add dump file for jump threading.
* tree.h (TDI_thread_jumps): New enum member.
* tree-cfg.c (tree_block_forwards_to): No longer static.
* tree-flow.h (tree_block_forwards_to): Prototype.
(tree_ssa_dominator_thread_jumps): Likewise.
* tree-optimize.c (optimize_function_tree): Call jump threader.
* tree-ssa-dom.c (tree_ssa_dominator_optimize_1): New function.
Common code for redundancy elimination and jump threading on
the dominator tree. Slightly different callback initialization
for redundancy elimination and jump threading. Initialize
block forwardable attribute.
(tree_ssa_dominator_optimize): Call tree_ssa_dominator_optimize_1.
(tree_ssa_dominator_thread_jumps): New function.
(thread_edge): Mark results of PHI nodes as needing rewriting if
we have threaded through a block with PHI nodes.
(thread_through_successor): If thread_through_phis is nonzero,
then allow jump threading through blocks with PHI nodes. If the
target block is a forwarder block, then forward the jump.
(thread_jumps_walk_stmts): Statement walker for dominator thread
jumping.
* tree-ssa-dom.c (record_equivalence_from_incoming_edge): Fix
comment typo.
