From 4a6a9f6f9284c78466fd80f6d85684b3b5edc905 Mon Sep 17 00:00:00 2001 From: Doug Gilmore Date: Sun, 5 Aug 2012 14:40:22 -0700 Subject: [PATCH 2/2] X8664 -m32 FP compilation mode change when compiling with GCC. When compiling with GCC at 32, add -mfpmath=sse -msse2, which prevents i387 FP instructions from being generated, otherwise the values for probabilities and frequencies can easily diverge between the 32 and 64 bit builds of the compiler. --- osprey/linux/make/gcommondefs | 7 ++++++- 1 files changed, 6 insertions(+), 1 deletions(-) diff --git a/osprey/linux/make/gcommondefs b/osprey/linux/make/gcommondefs index 90fa681..9659f1b 100644 --- a/osprey/linux/make/gcommondefs +++ b/osprey/linux/make/gcommondefs @@ -1,7 +1,7 @@ # -*- Makefile -*- # # -# Copyright (C) 2009 Advanced Micro Devices, Inc.
