re PR tree-optimization/52678 (internal compiler error: in vect_update_ivs_after_vectorizer, at tree-vect-loop-manip.c:1842)
2012-03-23 Richard Guenther <rguenther@suse.de>
PR tree-optimization/52678
* tree-vectorizer.h (struct _stmt_vec_info): Add
loop_phi_evolution_part member.
(STMT_VINFO_LOOP_PHI_EVOLUTION_PART): New define.
* tree-vect-loop.c (vect_analyze_scalar_cycles_1): Initialize
STMT_VINFO_LOOP_PHI_EVOLUTION_PART.
* tree-vect-loop-manip.c (vect_update_ivs_after_vectorizer):
Use the cached evolution part and the PHI nodes value from
the loop preheader edge instead of re-analyzing the evolution.
* gfortran.dg/pr52678.f: New testcase.
