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/pr49038.c | 42 +++++++++++++++++++++++++++++++++++++ 1 file changed, 42 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/vect/pr49038.c (limited to 'gcc/testsuite/gcc.dg/vect/pr49038.c') diff --git a/gcc/testsuite/gcc.dg/vect/pr49038.c b/gcc/testsuite/gcc.dg/vect/pr49038.c new file mode 100644 index 000000000..91c214ffd --- /dev/null +++ b/gcc/testsuite/gcc.dg/vect/pr49038.c @@ -0,0 +1,42 @@ +#include +#include + +#define COUNT 320 +#define MMAP_SIZE 0x10000 +#define ADDRESS 0x1122000000 +#define TYPE unsigned short + +#ifndef MAP_ANONYMOUS +#define MAP_ANONYMOUS MAP_ANON +#endif + +void __attribute__((noinline)) +foo (TYPE *__restrict a, TYPE *__restrict b) +{ + int n; + + for (n = 0; n < COUNT; n++) + a[n] = b[n * 2]; +} + +int +main (void) +{ + void *x; + size_t b_offset; + + x = mmap ((void *) ADDRESS, MMAP_SIZE, PROT_READ | PROT_WRITE, + MAP_PRIVATE | MAP_ANONYMOUS, -1, 0); + if (x == MAP_FAILED) + { + perror ("mmap"); + return 1; + } + + b_offset = MMAP_SIZE - (2 * COUNT - 1) * sizeof (TYPE); + foo ((unsigned short *) x, + (unsigned short *) ((char *) x + b_offset)); + return 0; +} + +/* { dg-final { cleanup-tree-dump "vect" } } */ -- cgit v1.2.3
