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/graphite/pr46185.c | 46 +++++++++++++++++++++++++++++++++ 1 file changed, 46 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/graphite/pr46185.c (limited to 'gcc/testsuite/gcc.dg/graphite/pr46185.c') diff --git a/gcc/testsuite/gcc.dg/graphite/pr46185.c b/gcc/testsuite/gcc.dg/graphite/pr46185.c new file mode 100644 index 000000000..36d46a41c --- /dev/null +++ b/gcc/testsuite/gcc.dg/graphite/pr46185.c @@ -0,0 +1,46 @@ +/* { dg-do run } */ +/* { dg-options "-O2 -floop-interchange -ffast-math -fno-ipa-cp" } */ + +#define DEBUG 0 +#if DEBUG +#include +#endif + +double u[1782225]; + +static int __attribute__((noinline)) +foo (int N, int *res) +{ + int i, j; + double sum = 0; + for (i = 0; i < N; i++) + for (j = 0; j < N; j++) + sum = sum + u[i + 1335 * j]; + + for (i = 0; i < N; i++) + u[1336 * i] *= 2; + + *res = sum + N + u[1336 * 2] + u[1336]; +} + +extern void abort (); + +int +main (void) +{ + int i, j, res; + + for (i = 0; i < 1782225; i++) + u[i] = 2; + + foo (1335, &res); + +#if DEBUG + fprintf (stderr, "res = %d \n", res); +#endif + + if (res != 3565793) + abort (); + + return 0; +} -- cgit v1.2.3
