re PR middle-end/57147 (setjmp call and if body wrongly elided (function runs off early end))
2013-05-06 Richard Biener <rguenther@suse.de>
PR middle-end/57147
* tree-cfg.c (gimple_purge_dead_abnormal_call_edges): If
the edge is also fallthru, preserve it and just clear the
abnormal flag.
* tree-cfgcleanup.c (remove_fallthru_edge): If the edge is
also complex, preserve that and just clear the fallthru flag.
* tree-inline.c (update_ssa_across_abnormal_edges): Also
update virtual operands.
* gcc.dg/torture/pr57147-1.c: New testcase.
* gcc.dg/torture/pr57147-2.c: Likewise.
* gcc.dg/torture/pr57147-3.c: Likewise.
