Well, I set it to -O2 for testing. Archlinux does set the CFLAGS so if this is wrong, Archlinux is doing it wrong? Archlinux's default CFLAGS are by the way: CFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fstack-protector --param=ssp-buffer-size=4 -D_FORTIFY_SOURCE=2" (I personally use -march=native) So I tried setting my CFLAGS to CFLAGS="$CFLAGS -fno-strict-aliasing". Compiling lib32 mesa looks like this now: gcc -m32 -c -I. -I../../../src/gallium/include -I../../../src/gallium/auxiliary -I../../../src/gallium/drivers -march=native -fomit-frame-pointer -O2 -pipe -fstack-protector --param=ssp-buffer-size=4 -D_FORTIFY_SOURCE=2 -fno-strict-aliasing -Wall -std=c99 -Werror=implicit-function-declaration -Werror=missing-prototypes -fno-strict-aliasing -fno-builtin-memcmp -m32 -march=native -fomit-frame-pointer -O2 -pipe -fstack-protector --param=ssp-buffer-size=4 -D_FORTIFY_SOURCE=2 -fno-strict-aliasing -fPIC -m32 -DUSE_X86_ASM -DUSE_MMX_ASM -DUSE_3DNOW_ASM -DUSE_SSE_ASM -D_GNU_SOURCE -DPTHREADS -DTEXTURE_FLOAT_ENABLED -DHAVE_POSIX_MEMALIGN -DIN_DRI_DRIVER -DUSE_XCB -DGLX_INDIRECT_RENDERING -DGLX_DIRECT_RENDERING -DGLX_USE_TLS -DPTHREADS -DUSE_EXTERNAL_DXTN_LIB=1 -DIN_DRI_DRIVER -DHAVE_ALIAS -DHAVE_MINCORE -DHAVE_LIBUDEV -DHAVE_XEXTPROTO_71 -D__STDC_CONSTANT_MACROS -DHAVE_LLVM=0x0300 -fvisibility=hidden -I/usr/include -D_GNU_SOURCE -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS util/u_rect.c -o util/u_rect.o -fno-strict-aliasing does not fix the wine crashes. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
