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/pr21101.c | 32 ++++++++++++++++++++++++++++++++ 1 file changed, 32 insertions(+) create mode 100644 gcc/testsuite/gcc.target/i386/pr21101.c (limited to 'gcc/testsuite/gcc.target/i386/pr21101.c') diff --git a/gcc/testsuite/gcc.target/i386/pr21101.c b/gcc/testsuite/gcc.target/i386/pr21101.c new file mode 100644 index 000000000..104b08cd2 --- /dev/null +++ b/gcc/testsuite/gcc.target/i386/pr21101.c @@ -0,0 +1,32 @@ +/* { dg-do compile } */ +/* { dg-options "-O2 -funroll-loops -march=nocona" } */ + +#include + +int W; +void f() +{ + int j; + int B, C; + unsigned char* S; + __m64 *T = (__m64 *) &W; + + for (j = 0; j < 16; j++, T++) + { + T[0] = T[1] = _mm_set1_pi8(*S); + S += W; + } + + C = 3 * B; + + __m64 E = _mm_set_pi16(3 * B, 3 * B, 3 * B, 5 * B); + __m64 G = _mm_set1_pi16(3 * B); + + for (j = 0; j < 16; j++) + { + __m64 R = _mm_set1_pi16(B + j * C); + R = _m_paddw(R, E); + R = _m_paddw(R, G); + T[0] = _mm_srai_pi16(R, 3); + } +} -- cgit v1.2.3
