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/pr48739-1.c | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/pr48739-1.c (limited to 'gcc/testsuite/gcc.dg/pr48739-1.c') diff --git a/gcc/testsuite/gcc.dg/pr48739-1.c b/gcc/testsuite/gcc.dg/pr48739-1.c new file mode 100644 index 000000000..4dcdca977 --- /dev/null +++ b/gcc/testsuite/gcc.dg/pr48739-1.c @@ -0,0 +1,27 @@ +/* PR tree-optimization/48739 */ +/* { dg-do compile } */ +/* { dg-require-effective-target pthread } */ +/* { dg-options "-O1 -ftree-parallelize-loops=2 -fno-tree-dominator-opts" } */ + +extern int g; +extern void bar (void); + +int +foo (int x) +{ + int a, b, *c = (int *) 0; + for (a = 0; a < 10; ++a) + { + bar (); + for (b = 0; b < 5; ++b) + { + x = 0; + c = &x; + g = 1; + } + } + *c = x; + for (x = 0; x != 10; x++) + ; + return g; +} -- cgit v1.2.3
