cfgexpand.c (expand_gimple_stmt_1): Use ops.code.
2015-04-23 Richard Biener <rguenther@suse.de>
* cfgexpand.c (expand_gimple_stmt_1): Use ops.code.
* cfgloop.c (verify_loop_structure): Verify the root loop node.
* except.c (duplicate_eh_regions): Call get_eh_region_from_lp_number_fn
instead of get_eh_region_from_lp_number.
* loop-init.c (fix_loop_structure): If we removed a loop, reset
the SCEV cache.
