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/20070302-1.c | 45 ++++++++++++++++++++++++++++++ 1 file changed, 45 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/20070302-1.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/20070302-1.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/20070302-1.c b/gcc/testsuite/gcc.dg/tree-ssa/20070302-1.c new file mode 100644 index 000000000..4b148f23d --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/20070302-1.c @@ -0,0 +1,45 @@ +/* { dg-do link } */ +/* { dg-options "-O2" } */ + +struct A +{ + int x; + float y; +}; + +volatile float X, Y; + +int __attribute__ ((__noinline__)) +baz (struct A *z, struct A *y) +{ + z->x = (int) X; + z->y = Y; + y->x = (int) X; + y->y = Y; +} + + +struct A B; + +float foo (int i) +{ + struct A *p, x, y, z; + + p = (i > 10) ? &x : &z; + x.y = 3.0; + p->x += baz (&z, &y); + X = z.y; + Y = p->y; + + /* This predicate should always evaluate to false.
