Author: José Fonseca <jfons...@vmware.com> Date: Fri Oct 9 13:22:42 2009 +0100 util: Force ESI register for cpuid's ebx result. Fixes a segfault and better code. Unfortunately using an arbitrary register ("=r") causes the gcc to abort when the code is optimized saying it can't satisfy the constraint. Setting seems to do the trick. --- src/gallium/auxiliary/util/u_cpu_detect.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/src/gallium/auxiliary/util/u_cpu_detect.c b/src/gallium/auxiliary/util/u_cpu_detect.c index 70ce25c..ded361c 100644 --- a/src/gallium/auxiliary/util/u_cpu_detect.c +++ b/src/gallium/auxiliary/util/u_cpu_detect.c @@ -346,7 +346,7 @@ cpuid(uint32_t ax, uint32_t *p) "cpuid\n\t" "xchgl %%ebx, %1" : "=a" (p[0]), - "=m" (p[1]), + "=S" (p[1]), "=c" (p[2]), "=d" (p[3]) : "0" (ax) _______________________________________________ mesa-commit mailing list mesa-commit@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-commit
