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/block-0.c | 46 +++++++++++++++++++++++++++++++++ 1 file changed, 46 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/graphite/block-0.c (limited to 'gcc/testsuite/gcc.dg/graphite/block-0.c') diff --git a/gcc/testsuite/gcc.dg/graphite/block-0.c b/gcc/testsuite/gcc.dg/graphite/block-0.c new file mode 100644 index 000000000..9bf97126d --- /dev/null +++ b/gcc/testsuite/gcc.dg/graphite/block-0.c @@ -0,0 +1,46 @@ +#define DEBUG 0 +#if DEBUG +#include +#endif + +#define N 1000 +int a[N]; + +static int __attribute__((noinline)) +foo (void) +{ + int j; + int i; + + /* This is not blocked as it is not profitable. */ + for (i = 0; i < N; i++) + for (j = 0; j < N; j++) + a[j] = a[i] + 1; + + return a[0]; +} + +extern void abort (); + +int +main (void) +{ + int i, res; + + for (i = 0; i < N; i++) + a[i] = i; + + res = foo (); + +#if DEBUG + fprintf (stderr, "res = %d \n", res); +#endif + + if (res != 1999) + abort (); + + return 0; +} + +/* { dg-final { scan-tree-dump-not "will be loop blocked" "graphite" } } */ +/* { dg-final { cleanup-tree-dump "graphite" } } */ -- cgit v1.2.3
