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/vect-reduc-1.c | 56 ++++++++++++++++++++++++++++++++ 1 file changed, 56 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vect/vect-reduc-1.c (limited to 'gcc/testsuite/gcc.dg/vect/vect-reduc-1.c') diff --git a/gcc/testsuite/gcc.dg/vect/vect-reduc-1.c b/gcc/testsuite/gcc.dg/vect/vect-reduc-1.c new file mode 100644 index 000000000..dbb154d12 --- /dev/null +++ b/gcc/testsuite/gcc.dg/vect/vect-reduc-1.c @@ -0,0 +1,56 @@ +/* { dg-require-effective-target vect_int } */ + +#include +#include "tree-vect.h" + +#define N 16 +#define DIFF 242 + +unsigned int ub[N] = {1,3,6,9,12,15,18,21,24,27,30,33,36,39,42,45}; +unsigned int uc[N] = {1,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15}; + +/* Test vectorization of reduction of unsigned-int. */ + +__attribute__ ((noinline)) +void main1 (unsigned int x, unsigned int max_result, unsigned int min_result) +{ + int i; + unsigned int udiff = 2; + unsigned int umax = x; + unsigned int umin = x; + + /* Summation. */ + for (i = 0; i < N; i++) { + udiff += (ub[i] - uc[i]); + } + + /* Maximum. */ + for (i = 0; i < N; i++) { + umax = umax < uc[i] ? uc[i] : umax; + } + + /* Minimum. */ + for (i = 0; i < N; i++) { + umin = umin > uc[i] ? uc[i] : umin; + } + + /* check results: */ + if (udiff != DIFF) + abort (); + if (umax != max_result) + abort (); + if (umin != min_result) + abort (); +} + +int main (void) +{ + check_vect (); + + main1 (100, 100, 1); + main1 (0, 15, 0); + return 0; +} + +/* { dg-final { scan-tree-dump-times "vectorized 3 loops" 1 "vect" { xfail { vect_no_int_add || vect_no_int_max } } } } */ +/* { dg-final { cleanup-tree-dump "vect" } } */ -- cgit v1.2.3
