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-strided-u16-i4.c | 73 +++++++++++++++++++++++++ 1 file changed, 73 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vect/vect-strided-u16-i4.c (limited to 'gcc/testsuite/gcc.dg/vect/vect-strided-u16-i4.c') diff --git a/gcc/testsuite/gcc.dg/vect/vect-strided-u16-i4.c b/gcc/testsuite/gcc.dg/vect/vect-strided-u16-i4.c new file mode 100644 index 000000000..da5a72855 --- /dev/null +++ b/gcc/testsuite/gcc.dg/vect/vect-strided-u16-i4.c @@ -0,0 +1,73 @@ +/* { dg-require-effective-target vect_int } */ + +#include +#include "tree-vect.h" + +#define N 128 + +typedef struct { + unsigned short a; + unsigned short b; + unsigned short c; + unsigned short d; +} s; + +__attribute__ ((noinline)) int +main1 (s *arr) +{ + int i; + s *ptr = arr; + s res[N]; + unsigned short x, y, z, w; + + for (i = 0; i < N; i++) + { + x = ptr->b - ptr->a; + y = ptr->d - ptr->c; + res[i].c = x + y; + z = ptr->a + ptr->c; + w = ptr->b + ptr->d; + res[i].a = z + w; + res[i].d = x + y; + res[i].b = x + y; + ptr++; + } + + /* check results: */ + for (i = 0; i < N; i++) + { + if (res[i].c != arr[i].b - arr[i].a + arr[i].d - arr[i].c + || res[i].a != arr[i].a + arr[i].c + arr[i].b + arr[i].d + || res[i].d != arr[i].b - arr[i].a + arr[i].d - arr[i].c + || res[i].b != arr[i].b - arr[i].a + arr[i].d - arr[i].c) + abort (); + } + + return 0; +} + +int main (void) +{ + int i; + s arr[N]; + + check_vect (); + + for (i = 0; i < N; i++) + { + arr[i].a = i; + arr[i].b = i * 2; + arr[i].c = 17; + arr[i].d = i+34; + if (arr[i].a == 178) + abort(); + } + + main1 (arr); + + return 0; +} + +/* { dg-final { scan-tree-dump-times "vectorized 1 loops" 1 "vect" { target { vect_interleave && vect_extract_even_odd } } } } */ +/* { dg-final { cleanup-tree-dump "vect" } } */ + -- cgit v1.2.3
