This has been introduced by revision 180028 Author: amodra Date: Sat Oct 15 10:36:00 2011 UTC (65 minutes, 35 seconds ago) Changed paths: 2 Log Message: * ifcvt.c (dead_or_predicable): Disable if-conversion when doing so is likely to kill a shrink-wrapping opportunity. I am now testing the new block protected by '#ifdef HAVE_simple_return' as done elsewhere.
