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/sse2-paddsw-1.c | 49 +++++++++++++++++++++++++++ 1 file changed, 49 insertions(+) create mode 100644 gcc/testsuite/gcc.target/i386/sse2-paddsw-1.c (limited to 'gcc/testsuite/gcc.target/i386/sse2-paddsw-1.c') diff --git a/gcc/testsuite/gcc.target/i386/sse2-paddsw-1.c b/gcc/testsuite/gcc.target/i386/sse2-paddsw-1.c new file mode 100644 index 000000000..5fec2f2a4 --- /dev/null +++ b/gcc/testsuite/gcc.target/i386/sse2-paddsw-1.c @@ -0,0 +1,49 @@ +/* { dg-do run } */ +/* { dg-options "-O2 -msse2" } */ +/* { dg-require-effective-target sse2 } */ + +#ifndef CHECK_H +#define CHECK_H "sse2-check.h" +#endif + +#ifndef TEST +#define TEST sse2_test +#endif + +#include CHECK_H + +#include + +static __m128i +__attribute__((noinline, unused)) +test (__m128i s1, __m128i s2) +{ + return _mm_adds_epi16 (s1, s2); +} + +static void +TEST (void) +{ + union128i_w u, s1, s2; + short e[8]; + int i, tmp; + + s1.x = _mm_set_epi16 (10,20,30,90,-80,-40,-100,-15); + s2.x = _mm_set_epi16 (11, 98, 76, -100, -34, -78, -39, 14); + u.x = test (s1.x, s2.x); + + for (i = 0; i < 8; i++) + { + tmp = s1.a[i] + s2.a[i]; + + if (tmp > 32767) + tmp = 32767; + if (tmp < -32768) + tmp = -32768; + + e[i] = tmp; + } + + if (check_union128i_w (u, e)) + abort (); +} -- cgit v1.2.3
