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/g++.dg/other/i386-8.C | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 gcc/testsuite/g++.dg/other/i386-8.C (limited to 'gcc/testsuite/g++.dg/other/i386-8.C') diff --git a/gcc/testsuite/g++.dg/other/i386-8.C b/gcc/testsuite/g++.dg/other/i386-8.C new file mode 100644 index 000000000..7de75c73c --- /dev/null +++ b/gcc/testsuite/g++.dg/other/i386-8.C @@ -0,0 +1,23 @@ +// PR rtl-optimization/45400 +// { dg-do compile { target i?86-*-* x86_64-*-* } } +// { dg-options "-O2 -msse2" } +// { dg-options "-O2 -msse2 -fpic" { target fpic } } +// { dg-require-effective-target sse2 } + +#include + +static inline unsigned short +bar (unsigned short x) +{ + return ((x << 8) | (x >> 8)); +} + +unsigned int +foo (float *x, short *y) +{ + __m128 a = _mm_set_ps1 (32767.5f); + __m128 b = _mm_mul_ps (_mm_load_ps (x), a); + __m64 c = _mm_cvtps_pi16 (b); + __builtin_memcpy (y, &c, sizeof (short) * 4); + y[0] = bar (y[0]); +} -- cgit v1.2.3
