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.dg/vect/slp-perm-2.c | 58 ++++++++++++++++++++++++++++++++++ 1 file changed, 58 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vect/slp-perm-2.c (limited to 'gcc/testsuite/gcc.dg/vect/slp-perm-2.c') diff --git a/gcc/testsuite/gcc.dg/vect/slp-perm-2.c b/gcc/testsuite/gcc.dg/vect/slp-perm-2.c new file mode 100644 index 000000000..1bc95e2e9 --- /dev/null +++ b/gcc/testsuite/gcc.dg/vect/slp-perm-2.c @@ -0,0 +1,58 @@ +/* { dg-require-effective-target vect_int } */ + +#include +#include "tree-vect.h" + +#define M00 100 +#define M10 216 +#define M01 1322 +#define M11 13 +#define M02 74 +#define M12 191 + +#define N 16 + +void foo (unsigned int *__restrict__ pInput, unsigned int *__restrict__ pOutput) +{ + unsigned int i, a, b; + + for (i = 0; i < N / 2; i++) + { + a = *pInput++; + b = *pInput++; + + *pOutput++ = M00 * a + M01 * b; + *pOutput++ = M10 * a + M11 * b; + } +} + +int main (int argc, const char* argv[]) +{ + unsigned int input[N], output[N], i; + unsigned int check_results[N] = {1322, 13, 4166, 471, 7010, 929, 9854, 1387, 12698, 1845, 15542, 2303, 18386, 2761, 21230, 3219}; + + check_vect (); + + for (i = 0; i < N; i++) + { + input[i] = i%256; + output[i] = 0; + __asm__ volatile (""); + } + + foo (input, output); + + for (i = 0; i < N; i++) + { + if (output[i] != check_results[i]) + abort (); + __asm__ volatile (""); + } + + return 0; +} + +/* { dg-final { scan-tree-dump-times "vectorized 1 loops" 1 "vect" { target vect_perm } } } */ +/* { dg-final { scan-tree-dump-times "vectorizing stmts using SLP" 1 "vect" { target vect_perm } } } */ +/* { dg-final { cleanup-tree-dump "vect" } } */ + -- cgit v1.2.3
