gimplify.c (gimple_regimplify_operands): Only mark the LHS of statements for renaming.
2012-05-14 Richard Guenther <rguenther@suse.de>
* gimplify.c (gimple_regimplify_operands): Only mark the LHS
of statements for renaming.
(force_gimple_operand_1): Likewise, consistently for both
calls to force_gimple_operand and force_gimple_operand_gsi.
