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-16.c | 71 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 71 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vect/slp-16.c (limited to 'gcc/testsuite/gcc.dg/vect/slp-16.c') diff --git a/gcc/testsuite/gcc.dg/vect/slp-16.c b/gcc/testsuite/gcc.dg/vect/slp-16.c new file mode 100644 index 000000000..e5469d46c --- /dev/null +++ b/gcc/testsuite/gcc.dg/vect/slp-16.c @@ -0,0 +1,71 @@ +/* { dg-require-effective-target vect_int } */ + +#include +#include "tree-vect.h" + +#define N 8 + +unsigned int out[N*8]; +unsigned int 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 int in2[N*16] = {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 int out2[N*16]; + +int +main1 () +{ + int i; + unsigned int a0, a1, a2, a3, a4, a5, a6, a7, b1, b0, b2, b3, b4, b5, b6, b7; + + /* SLP group of size that is not a multiple of vector size. + Unrolling by 2. */ + for (i = 0; i < N; i++) + { + a0 = in[i*2] + 5; + a1 = in[i*2 + 1] + 6; + + b0 = a0 * 3; + b1 = a1 * 2; + + out[i*2] = b0 - 2; + out[i*2 + 1] = b1 - 3; + + out2[i*6] = in2[i*6] * 2; + out2[i*6 + 1] = in2[i*6 + 1] * 3; + out2[i*6 + 2] = in2[i*6 + 2] * 4; + out2[i*6 + 3] = in2[i*6 + 3] * 2; + out2[i*6 + 4] = in2[i*6 + 4] * 4; + out2[i*6 + 5] = in2[i*6 + 5] * 3; + } + + /* check results: */ + for (i = 0; i < N; i++) + { + if (out[i*2] != (in[i*2] + 5) * 3 - 2 + || out[i*2 + 1] != (in[i*2 + 1] + 6) * 2 - 3 + || out2[i*6] != in2[i*6] * 2 + || out2[i*6 + 1] != in2[i*6 + 1] * 3 + || out2[i*6 + 2] != in2[i*6 + 2] * 4 + || out2[i*6 + 3] != in2[i*6 + 3] * 2 + || out2[i*6 + 4] != in2[i*6 + 4] * 4 + || out2[i*6 + 5] != in2[i*6 + 5] * 3) + abort (); + } + + + + return 0; +} + +int main (void) +{ + check_vect (); + + main1 (); + + return 0; +} + +/* { dg-final { scan-tree-dump-times "vectorized 1 loops" 1 "vect" { target vect_int_mult } } } */ +/* { dg-final { scan-tree-dump-times "vectorizing stmts using SLP" 2 "vect" { target vect_int_mult } } } */ +/* { dg-final { cleanup-tree-dump "vect" } } */ + -- cgit v1.2.3
