re PR tree-optimization/43379 (ICE: error: SSA_NAME_OCCURS_IN_ABNORMAL_PHI should be set with -O2 -ftracer)
2010-03-16 Richard Guenther <rguenther@suse.de>
PR middle-end/43379
* tree-cfg.c (gimple_merge_blocks): When propagating virtual
PHI operands make sure to merge SSA_NAME_OCCURS_IN_ABNORMAL_PHI
properly.
* gcc.dg/pr43379.c: New testcase.
