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-26.c | 52 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 52 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vect/slp-26.c (limited to 'gcc/testsuite/gcc.dg/vect/slp-26.c') diff --git a/gcc/testsuite/gcc.dg/vect/slp-26.c b/gcc/testsuite/gcc.dg/vect/slp-26.c new file mode 100644 index 000000000..6821b2ced --- /dev/null +++ b/gcc/testsuite/gcc.dg/vect/slp-26.c @@ -0,0 +1,52 @@ +/* { dg-require-effective-target vect_int } */ + +#include +#include "tree-vect.h" + +#define N 8 + +int +main1 () +{ + int i; + unsigned short in[N*8] = {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63}; + unsigned short out[N*8], a[N], b[N] = {3,6,9,12,15,18,21,24}; + + /* Partial SLP is not supported. */ + for (i = 0; i < N; i++) + { + out[i*4] = in[i*4]; + out[i*4 + 1] = in[i*4 + 1]; + out[i*4 + 2] = in[i*4 + 2]; + out[i*4 + 3] = in[i*4 + 3]; + + a[i] = b[i] / 3; + } + + /* check results: */ + for (i = 0; i < N; i++) + { + if (out[i*4] != in[i*4] + || out[i*4 + 1] != in[i*4 + 1] + || out[i*4 + 2] != in[i*4 + 2] + || out[i*4 + 3] != in[i*4 + 3] + || a[i] != b[i] / 3) + abort (); + } + + return 0; +} + +int main (void) +{ + check_vect (); + + main1 (); + + return 0; +} + +/* { dg-final { scan-tree-dump-times "vectorized 0 loops" 1 "vect" } } */ +/* { dg-final { scan-tree-dump-times "vectorizing stmts using SLP" 0 "vect" } } */ +/* { dg-final { cleanup-tree-dump "vect" } } */ + -- cgit v1.2.3
