--- Comment #15 from James Cook <james.c...@utoronto.ca> --- I can reproduce the problem on my machine. I'm using the tarball at ftp://ftp.freedesktop.org/pub/mesa/${version}/MesaLib-${version}.tar.bz2 , where version is 9.2.2, with some distribution-specific patches and configuration options (NixOS x-updates branch). If you think these might be interfering, let me know and I'll see if I can build without the changes. Here's my output for GALLIUM_DUMP_CPU=1 ./lp_test_arit (with LD_LIBRARY_PATH set for annoying reasons): $ LD_LIBRARY_PATH=/tmp/nix-build-mesa-noglu-9.2.2.drv-0/Mesa-9.2.2/src/gallium/auxiliary/gallivm/.libs/lp_bld_init.o0000000000000000 GALLIUM_DUMP_CPU=1 ./lp_test_arit util_cpu_caps.nr_cpus = 3 util_cpu_caps.x86_cpu_type = 9 util_cpu_caps.cacheline = 64 util_cpu_caps.has_tsc = 1 util_cpu_caps.has_mmx = 1 util_cpu_caps.has_mmx2 = 1 util_cpu_caps.has_sse = 1 util_cpu_caps.has_sse2 = 1 util_cpu_caps.has_sse3 = 1 util_cpu_caps.has_ssse3 = 0 util_cpu_caps.has_sse4_1 = 0 util_cpu_caps.has_sse4_2 = 0 util_cpu_caps.has_avx = 0 util_cpu_caps.has_3dnow = 1 util_cpu_caps.has_3dnow_ext = 1 util_cpu_caps.has_altivec = 0 floor(-0): ref = -1, out = 0, precision = -0.000000 bits, FAIL ceil(0): ref = 1, out = 0, precision = -0.000000 bits, FAIL fract(-0): ref = 0.99999994, out = -0, precision = -0.000000 bits, FAIL Here's the end of the testing output, from before I ran the above command: Testing PIPE_FORMAT_B4G4R4X4_UNORM (unorm8) ...
