re PR tree-optimization/35609 ("is used uninitialized in this function" should be may warning)
2008-03-19 Richard Guenther <rguenther@suse.de>
PR middle-end/35609
* tree-ssa.c (always_executed): New global flag.
(warn_uninitialized_var): If !always_executed warn with "maybe"
instead of "is".
(execute_early_warn_uninitialized): Compute post-dominators.
Initialize always_executed before processing each basic block.
* gcc.dg/testsuite/uninit-15.c: New testcase.
* gcc.dg/testsuite/uninit-16.c: Likewise.
