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/bb-slp-3.c | 47 ++++++++++++++++++++++++++++++++++++ 1 file changed, 47 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vect/bb-slp-3.c (limited to 'gcc/testsuite/gcc.dg/vect/bb-slp-3.c') diff --git a/gcc/testsuite/gcc.dg/vect/bb-slp-3.c b/gcc/testsuite/gcc.dg/vect/bb-slp-3.c new file mode 100644 index 000000000..fee62d7f9 --- /dev/null +++ b/gcc/testsuite/gcc.dg/vect/bb-slp-3.c @@ -0,0 +1,47 @@ +/* { dg-require-effective-target vect_int } */ + +#include +#include "tree-vect.h" + +#define N 16 + +unsigned int out[N]; +unsigned int in[N] = {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15}; + +int i; +__attribute__ ((noinline)) int +main1 () +{ + unsigned int *pin = &in[0]; + unsigned int *pout = &out[0]; + + *pout++ = *pin++; + *pout++ = *pin++; + *pout++ = *pin++; + *pout++ = *pin++; + + if (i) + __asm__ volatile ("" : : : "memory"); + + /* Check results. */ + if (out[0] != in[0] + || out[1] != in[1] + || out[2] != in[2] + || out[3] != in[3]) + abort(); + + return 0; +} + +int main (void) +{ + check_vect (); + + main1 (); + + return 0; +} + +/* { dg-final { scan-tree-dump-times "basic block vectorized using SLP" 1 "slp" } } */ +/* { dg-final { cleanup-tree-dump "slp" } } */ + -- cgit v1.2.3
