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/xop-shift2-vector.c | 35 +++++++++++++++++++++++ 1 file changed, 35 insertions(+) create mode 100644 gcc/testsuite/gcc.target/i386/xop-shift2-vector.c (limited to 'gcc/testsuite/gcc.target/i386/xop-shift2-vector.c') diff --git a/gcc/testsuite/gcc.target/i386/xop-shift2-vector.c b/gcc/testsuite/gcc.target/i386/xop-shift2-vector.c new file mode 100644 index 000000000..e59c30d02 --- /dev/null +++ b/gcc/testsuite/gcc.target/i386/xop-shift2-vector.c @@ -0,0 +1,35 @@ +/* Test that the compiler properly optimizes vector shift instructions into + psha/pshl on XOP systems. */ + +/* { dg-do compile } */ +/* { dg-require-effective-target lp64 } */ +/* { dg-options "-O2 -mxop -ftree-vectorize" } */ + +extern void exit (int); + +typedef long __m128i __attribute__ ((__vector_size__ (16), __may_alias__)); + +#define SIZE 10240 + +union { + __m128i i_align; + int i32[SIZE]; + unsigned u32[SIZE]; +} a, b, c; + +void +right_sign_shift32 (void) +{ + int i; + + for (i = 0; i < SIZE; i++) + a.i32[i] = b.i32[i] >> c.i32[i]; +} + +int main () +{ + right_sign_shfit32 (); + exit (0); +} + +/* { dg-final { scan-assembler "vpshad" } } */ -- cgit v1.2.3
