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/no-scevccp-vect-iv-3.c | 28 ++++++++++++++++++++++++ 1 file changed, 28 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vect/no-scevccp-vect-iv-3.c (limited to 'gcc/testsuite/gcc.dg/vect/no-scevccp-vect-iv-3.c') diff --git a/gcc/testsuite/gcc.dg/vect/no-scevccp-vect-iv-3.c b/gcc/testsuite/gcc.dg/vect/no-scevccp-vect-iv-3.c new file mode 100644 index 000000000..9bf3b4b76 --- /dev/null +++ b/gcc/testsuite/gcc.dg/vect/no-scevccp-vect-iv-3.c @@ -0,0 +1,28 @@ +/* { dg-do compile } */ +/* { dg-require-effective-target vect_int } */ + +#include +#include "tree-vect.h" + +#define N 26 + +__attribute__ ((noinline)) +unsigned int main1 () +{ + unsigned short i; + unsigned int intsum = 0; + + /* vectorization of reduction with induction, and widenning sum: + sum shorts into int. + Need -fno-tree-scev-cprop or else the loop is eliminated. */ + for (i = 0; i < N; i++) + { + intsum += i; + } + + return intsum; +} + +/* { dg-final { scan-tree-dump-times "vectorized 1 loops" 1 "vect" { target vect_widen_sum_hi_to_si } } } */ +/* { dg-final { scan-tree-dump-times "vect_recog_widen_sum_pattern: detected" 1 "vect" { target vect_widen_sum_hi_to_si } } } */ +/* { dg-final { cleanup-tree-dump "vect" } } */ -- cgit v1.2.3
