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-dri-xcb | 3 +++ 1 file changed, 3 insertions(+) (limited to 'configs/linux-dri-xcb') diff --git a/configs/linux-dri-xcb b/configs/linux-dri-xcb index 1f233f07f5..69643718ad 100644 --- a/configs/linux-dri-xcb +++ b/configs/linux-dri-xcb @@ -32,6 +32,9 @@ CFLAGS = -Wall -Wmissing-prototypes $(OPT_FLAGS) $(PIC_FLAGS) $(ARCH_FLAGS) \ CXXFLAGS = -Wall $(OPT_FLAGS) $(PIC_FLAGS) $(ARCH_FLAGS) $(DEFINES) +# Work around aliasing bugs - developers should comment this out +CFLAGS += -fno-strict-aliasing +CXXFLAGS += -fno-strict-aliasing ASM_SOURCES = -- cgit v1.2.3
