re PR tree-optimization/56982 (Bad optimization with setjmp())
2013-04-19 Richard Biener <rguenther@suse.de>
PR tree-optimization/56982
* builtins.def (BUILT_IN_LONGJMP): longjmp is not a leaf
function.
* gimplify.c (gimplify_call_expr): Notice special calls.
(gimplify_modify_expr): Likewise.
* tree-cfg.c (make_abnormal_goto_edges): Handle setjmp-like
abnormal control flow receivers.
(call_can_make_abnormal_goto): Handle cfun->calls_setjmp
in the same way as cfun->has_nonlocal_labels.
(gimple_purge_dead_abnormal_call_edges): Likewise.
(stmt_starts_bb_p): Make setjmp-like abnormal control flow
receivers start a basic-block.
* gcc.c-torture/execute/pr56982.c: New testcase.
