From 013dbcd6111bc880e65ed00a7ca31e19230a81d5 Mon Sep 17 00:00:00 2001 From: Dan Nicholson Date: Wed, 31 Oct 2007 09:47:39 -0700 Subject: Add -fno-strict-aliasing workaround for Linux GCC targets Most Linux distros work around aliasing problems in Mesa by compiling with the GCC option -fno-strict-aliasing. Two examples: https://bugs.freedesktop.org/show_bug.cgi?id=6046 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=394311 This makes -fno-strict-aliasing the default with a comment that developers should consider commenting it out. There is a already a note about these bugs in docs/helpwanted.html. --- configs/linux-directfb | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'configs/linux-directfb') diff --git a/configs/linux-directfb b/configs/linux-directfb index 09332f4808..2a9843e93c 100644 --- a/configs/linux-directfb +++ b/configs/linux-directfb @@ -13,6 +13,10 @@ CFLAGS = -Wall -O3 -ffast-math -fPIC -std=c99 -D_GNU_SOURCE -D_POSIX_SOURCE -D CXXFLAGS = -Wall -O3 -fPIC -D_POSIX_SOURCE -D_POSIX_C_SOURCE=199309L -D_SVID_SOURCE -D_BSD_SOURCE +# Work around aliasing bugs - developers should comment this out +CFLAGS += -fno-strict-aliasing +CXXFLAGS += -fno-strict-aliasing + HAVE_X86 = $(shell uname -m | grep 'i[3-6]86' >/dev/null && echo yes) ifeq ($(HAVE_X86), yes) CFLAGS += -DUSE_X86_ASM -DUSE_MMX_ASM -DUSE_3DNOW_ASM -DUSE_SSE_ASM -- cgit v1.2.3
