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.dg/vect/vect-strided-a-u8-i8-gap7.c | 86 ++++++++++++++++++++++ 1 file changed, 86 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vect/vect-strided-a-u8-i8-gap7.c (limited to 'gcc/testsuite/gcc.dg/vect/vect-strided-a-u8-i8-gap7.c') diff --git a/gcc/testsuite/gcc.dg/vect/vect-strided-a-u8-i8-gap7.c b/gcc/testsuite/gcc.dg/vect/vect-strided-a-u8-i8-gap7.c new file mode 100644 index 000000000..8dfb21be9 --- /dev/null +++ b/gcc/testsuite/gcc.dg/vect/vect-strided-a-u8-i8-gap7.c @@ -0,0 +1,86 @@ +/* { dg-require-effective-target vect_int } */ + +#include +#include "tree-vect.h" + +#define N 16 + +typedef struct { + unsigned char a; + unsigned char b; + unsigned char c; + unsigned char d; + unsigned char e; + unsigned char f; + unsigned char g; + unsigned char h; +} s; + +__attribute__ ((noinline)) int +main1 () +{ + int i; + s arr[N]; + s *ptr = arr; + s res[N]; + unsigned char u, t, s, x, y, z, w; + + for (i = 0; i < N; i++) + { + arr[i].a = i; + arr[i].b = i * 2; + arr[i].c = 17; + arr[i].d = i+34; + arr[i].e = i * 3 + 5; + arr[i].f = i * 5; + arr[i].g = i - 3; + arr[i].h = 67; + if (arr[i].a == 178) + abort(); + } + + for (i = 0; i < N; i++) + { + u = ptr->b - ptr->a; + t = ptr->d - ptr->c; + res[i].c = u + t; + x = ptr->b + ptr->d; + res[i].a = ptr->a + x; + res[i].d = u + t; + s = ptr->h - ptr->a; + res[i].b = s + t; + res[i].f = ptr->f + ptr->h; + res[i].e = ptr->b + ptr->e; + res[i].h = ptr->d; + res[i].g = u + t; + 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].b + arr[i].d + || res[i].d != arr[i].b - arr[i].a + arr[i].d - arr[i].c + || res[i].b != arr[i].h - arr[i].a + arr[i].d - arr[i].c + || res[i].f != arr[i].f + arr[i].h + || res[i].e != arr[i].b + arr[i].e + || res[i].h != arr[i].d + || res[i].g != arr[i].b - arr[i].a + arr[i].d - arr[i].c) + abort(); + } +} + + +int main (void) +{ + check_vect (); + + main1 (); + + 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
