------- Additional Comments From schwab at suse dot de 2005-06-10 17:32 -------
Triggered by the combination of these two patches:
2005-05-25 Ulrich Weigand <[EMAIL PROTECTED]>
* reload1.c (verify_initial_elim_offsets): Return boolean status
instead of aborting.
(reload): Adapt verify_initial_elim_offsets call site. Restart
main loop if some initial elimination offsets changed.
2005-04-22 Jeff Law <[EMAIL PROTECTED]>
* tree-ssa-dom.c (block_defs_stack): Remove, no longer needed.
(restore_currdefs_to_original_value): Likewise.
(register_definitions_for_stmt): Likewise.
(tree_ssa_dominator_optimize): No longer initialize CURRENT_DEF
for each variable. Do not allocate/free block_defs_stack either.
Do not iterate if we just thread jumps. Only iterate if the
tree_cleanup_cfg does useful work (temporary).
(dom_opt_initialize_block): No longer push a marker on
BLOCK_DEFS_STACK.
(dom_opt_finalize_block): Removal call to restore currdefs.
Relax restrictions for recording edge equivalences.
(record_equivalences_from_phis): No longer need to track
CURRENT_DEF.
(optimize_stmt): Similarly.
(thread_across_edge): Simplify by removing the requirement that
statements in the block we are threading through must be nops.
(initialize_hash_element): Handle GOTO_EXPR.
