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/tree-ssa/20041008-1.c | 38 ++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/20041008-1.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/20041008-1.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/20041008-1.c b/gcc/testsuite/gcc.dg/tree-ssa/20041008-1.c new file mode 100644 index 000000000..ca24427b6 --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/20041008-1.c @@ -0,0 +1,38 @@ +/* { dg-do run } */ +/* { dg-options "-O2" } */ + +struct A { + int x; + int y; +}; + +baz (struct A *a) +{ + a->x = 3; + a->y = 2; +} + +foo (int i) +{ + struct A a; + + /* Make sure we can't scalarize 'a'. */ + baz (&a); + + if (i > 10) + a.x = i; + else + a.x = i; + + /* Copy propagation should prove that this predicate is always false. */ + if (a.x != i) + link_error (); + + return a.x; +} + +main () +{ + foo (30); + return 0; +} -- cgit v1.2.3
