re PR tree-optimization/59164 (ice: tree check: expected tree that contains ‘decl minimal’ structure, have ‘integer_cst’ in get_var_info, at tree-into-ssa.c:380)
2013-11-19 Richard Biener <rguenther@suse.de>
PR tree-optimization/59164
* tree-vect-loop-manip.c (vect_update_ivs_after_vectorizer):
Uncomment assert.
* tree-vect-loop.c (vect_analyze_loop_operations): Adjust
check whether we can create an epilogue loop to reflect the
cases where we create one.
* gcc.dg/torture/pr59164.c: New testcase.
