From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/testsuite/gcc.target/i386/sse4_2-popcnt.h | 41 +++++++++++++++++++++++++++ 1 file changed, 41 insertions(+) create mode 100644 gcc/testsuite/gcc.target/i386/sse4_2-popcnt.h (limited to 'gcc/testsuite/gcc.target/i386/sse4_2-popcnt.h') diff --git a/gcc/testsuite/gcc.target/i386/sse4_2-popcnt.h b/gcc/testsuite/gcc.target/i386/sse4_2-popcnt.h new file mode 100644 index 000000000..ce06ba1b8 --- /dev/null +++ b/gcc/testsuite/gcc.target/i386/sse4_2-popcnt.h @@ -0,0 +1,41 @@ +#include "sse4_2-check.h" + +#include + +#define NUM 1024 + +static int +compute_popcnt (TYPE v) +{ + int ret; + int i; + + ret = 0; + for (i = 0; i < sizeof(v) * 8; i++) + if ((v & ((TYPE)1 << (TYPE) i))) + ret++; + + return ret; +} + +static void +sse4_2_test (void) +{ + int i; + TYPE vals[NUM]; + TYPE res; + + for (i = 0; i < NUM; i++) + { + vals[i] = rand (); + if (sizeof (TYPE) > 4) + vals[i] |= (TYPE)rand() << (TYPE)(sizeof (TYPE) * 4); + } + + for (i=0; i < NUM; i++) + { + res = POPCNT (vals[i]); + if (res != compute_popcnt (vals[i])) + abort (); + } +} -- cgit v1.2.3
