From 3987b9db30f95cd055f68d302da8e9c474b6feea Mon Sep 17 00:00:00 2001 From: Jan Hubicka Date: Thu, 10 Jan 2002 11:21:30 +0100 Subject: [PATCH] optabs.c (expand_fix): Look for wider integer modes first. * optabs.c (expand_fix): Look for wider integer modes first. * i386.md (mov?f): Avoid the fake const double trick for medium memory model. (min?f*/max?f*): Prohibit memory operands for i387 variant. (fop_df_4): Disable for SSE compilation.
