From 030b8c48a92ebb2ce98d6a41a399d97184226b7d Mon Sep 17 00:00:00 2001 From: Uros Bizjak Date: Fri, 6 Aug 2010 14:13:25 +0200 Subject: [PATCH] expmed.c (expand_mult_const): Expand shift into temporary. 2010-08-06 Uros Bizjak * expmed.c (expand_mult_const) : Expand shift into temporary. Emit move from temporary to accum, so REG_EQUAL note will be attached to this insn in correct mode. 2010-08-06 Uros Bizjak * config/i386/i386.c (ix86_decompose_address): Check for SI_REG using REGNO of base_reg directly.
