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/pr43430-1.c | 39 +++++++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vect/pr43430-1.c (limited to 'gcc/testsuite/gcc.dg/vect/pr43430-1.c') diff --git a/gcc/testsuite/gcc.dg/vect/pr43430-1.c b/gcc/testsuite/gcc.dg/vect/pr43430-1.c new file mode 100644 index 000000000..9eaa23cca --- /dev/null +++ b/gcc/testsuite/gcc.dg/vect/pr43430-1.c @@ -0,0 +1,39 @@ +/* { dg-require-effective-target vect_int } */ + +#include +#include "tree-vect.h" + +#define N 16 + +typedef int myint; +myint data_ch1[N + 1] = + { 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30 }; +myint data_ch2[N + 1] = + { 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30 }; +#define SUM 480 + +__attribute__ ((noinline)) int +foo (myint * s1, myint * s2, int stride) +{ + int score = 0; + int x; + for (x = 0; x < N; x++) + score += ((s1[x] - s1[x + stride] + s2[x + stride]) >= 0 ? + s1[x] + s2[x + stride] : + s2[x + stride]); + + if (score != SUM) + abort (); + + return 0; +} + +int +main (void) +{ + check_vect (); + return foo (data_ch1, data_ch2, 1); +} + +/* { dg-final { scan-tree-dump-times "vectorized 1 loops" 1 "vect" { target vect_condition } } } */ +/* { dg-final { cleanup-tree-dump "vect" } } */ -- cgit v1.2.3
