Hi Michel,

It looks like fract is seriously busted.

The processor doesn't have SSE41, so no ROUNDPS instruction.

This can be reproduced on other processors doing:

diff --git a/src/gallium/auxiliary/gallivm/lp_bld_init.c
index 050eba7..d677dbb 100644
--- a/src/gallium/auxiliary/gallivm/lp_bld_init.c
+++ b/src/gallium/auxiliary/gallivm/lp_bld_init.c
@@ -489,7 +489,7 @@ lp_build_init(void)

    gallivm_initialized = TRUE;

-#if 0
+#if 1
    /* For simulating less capable machines */
    util_cpu_caps.has_sse3 = 0;
    util_cpu_caps.has_ssse3 = 0;
