Log message:
2003-06-11 Daniel Berlin <dberlin@dberlin.org>
* tree-ssa-pre.c: add graph_dump_file, graph_dump_flags.
(finalize_1): Modify to use temporary in expr_info structure,
remove temporary from arguments.
Use bsi_insert_on_edge for ephi insertions.
Set EREF_TEMP on inserted euses.
(repair_phi_injury): Note (to dump file) injuries we have
repaired already.
(repair_use_injury): Ditto.
(repair_euse_injury): Ditto.
(count_stmts_in_bb): Count both forwards and backwards, and make
sure the numbers agree. This makes sure both the head and end are
updated properly.
(code_motion): Use the EREF_TEMP, rather than calculating the
reaching def, when possible, because it's faster.
Add the phi we created when we insert the ephi. We should always
be able to get the reaching def of the ephi from EREF_TEMP (since
the args should have already been inserted, or in the case of
phi's, have a phi already allocated), so abort if we can't.
(create_expr_ref): Take expr_info parameter. Make a phi for the
ephi's, but don't add to the bb yet. Update all callers.
(get_default_def): New function.
(get_reaching_def): Use it to find the default def when we hit the
top of the dom tree.
(struct expr_info): Add temp.
(new_rename_1): Dump out occurrences after rename 1, but before
rename 2.
(requires_edge_placement): Now that we can insert on edges, we
shouldn't need this, so make it always return false.
Will remove unless something bad comes up.
(pre_expression): Start working on dumping the redundancy graph.
* tree.h (struct treeeref_common): Add the temp member.
Add EREF_TEMP macro.
(tree_dump_index): Reorder to match actual optimization order.
Add TDI_predot.
* tree-dump.c: Ditto.
