Makefile.in (tree-tailcall.o): Add $(CFGLOOP_H) dependency.
2013-02-08 Richard Biener <rguenther@suse.de>
* Makefile.in (tree-tailcall.o): Add $(CFGLOOP_H) dependency.
* ipa-pure-const.c (analyze_function): Avoid calling
mark_irreducible_loops twice.
* tree-tailcall.c (tree_optimize_tail_calls_1): Mark loops
for fixup.
