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/pr23376.c | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 gcc/testsuite/gcc.target/i386/pr23376.c (limited to 'gcc/testsuite/gcc.target/i386/pr23376.c') diff --git a/gcc/testsuite/gcc.target/i386/pr23376.c b/gcc/testsuite/gcc.target/i386/pr23376.c new file mode 100644 index 000000000..0dee77f6b --- /dev/null +++ b/gcc/testsuite/gcc.target/i386/pr23376.c @@ -0,0 +1,21 @@ +/* { dg-do compile } */ +/* { dg-options "-O1 -mmmx -funroll-loops -fvariable-expansion-in-unroller" } */ + +typedef int __m64 __attribute__ ((__vector_size__ (8))); +typedef int __v2si __attribute__ ((__vector_size__ (8))); + +static __inline __m64 __attribute__((__always_inline__)) +_mm_add_pi32 (__m64 __m1, __m64 __m2) +{ + return (__m64) __builtin_ia32_paddd ((__v2si)__m1, (__v2si)__m2); +} + +__m64 +simple_block_diff_up_mmx_4 (const int width, __m64 ref1) +{ + __m64 sum; + int count = width >>1; + while (count--) + sum = _mm_add_pi32 (sum, ref1); + return sum; +} -- cgit v1.2.3
