re PR rtl-optimization/70484 (Wrong optimization with aliasing and access via char)
2016-04-04 Richard Biener <rguenther@suse.de>
PR rtl-optimization/70484
* rtl.h (canon_output_dependence): Declare.
* alias.c (canon_output_dependence): New function.
* dse.c (record_store): Use canon_output_dependence rather
than canon_true_dependence.
* gcc.dg/torture/pr70484.c: New testcase.
