From ffebefa11424411d7e54a3a1223fe87a2de6e596 Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Wed, 19 Jun 2013 23:46:15 +0200 Subject: [PATCH] util: (trivial) add has_popcnt field Not used yet but there's a couple of places in llvmpipe which should use this (occlusion count is currently very inefficent if there's no cpu popcnt instruction). --- src/gallium/auxiliary/util/u_cpu_detect.c | 1 + src/gallium/auxiliary/util/u_cpu_detect.h | 1 + 2 files changed, 2 insertions(+) diff --git a/src/gallium/auxiliary/util/u_cpu_detect.c b/src/gallium/auxiliary/util/u_cpu_detect.c index 763b5cc220f..b118fc8ae36 100644 --- a/src/gallium/auxiliary/util/u_cpu_detect.c +++ b/src/gallium/auxiliary/util/u_cpu_detect.c @@ -283,6 +283,7 @@ util_cpu_detect(void) util_cpu_caps.has_ssse3 = (regs2[2] >> 9) & 1; /* 0x0000020 */ util_cpu_caps.has_sse4_1 = (regs2[2] >> 19) & 1; util_cpu_caps.has_sse4_2 = (regs2[2] >> 20) & 1; + util_cpu_caps.has_popcnt = (regs2[2] >> 23) & 1; util_cpu_caps.has_avx = (regs2[2] >> 28) & 1; util_cpu_caps.has_f16c = (regs2[2] >> 29) & 1; util_cpu_caps.has_mmx2 = util_cpu_caps.has_sse; /* SSE cpus supports mmxext too */ diff --git a/src/gallium/auxiliary/util/u_cpu_detect.h b/src/gallium/auxiliary/util/u_cpu_detect.h index 21c2f048ff4..f9cd6475e45 100644 --- a/src/gallium/auxiliary/util/u_cpu_detect.h +++ b/src/gallium/auxiliary/util/u_cpu_detect.h @@ -62,6 +62,7 @@ struct util_cpu_caps { unsigned has_ssse3:1; unsigned has_sse4_1:1; unsigned has_sse4_2:1; + unsigned has_popcnt:1; unsigned has_avx:1; unsigned has_f16c:1; unsigned has_3dnow:1; -- 2.30.2
