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/vrp12.c | 23 +++++++++++++++++++++++ 1 file changed, 23 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/tree-ssa/vrp12.c (limited to 'gcc/testsuite/gcc.dg/tree-ssa/vrp12.c') diff --git a/gcc/testsuite/gcc.dg/tree-ssa/vrp12.c b/gcc/testsuite/gcc.dg/tree-ssa/vrp12.c new file mode 100644 index 000000000..1714a561c --- /dev/null +++ b/gcc/testsuite/gcc.dg/tree-ssa/vrp12.c @@ -0,0 +1,23 @@ +/* { dg-do link } */ +/* { dg-options -O2 } */ + +foo (int i) +{ + int x; + + x = i; + if (i < -10) + { + x = __builtin_abs (i); + /* VRP was incorrectly folding this to if (1). */ + if (x < 0) + link_error (); + } + + return x; +} + +main() +{ + foo (-30); +} -- cgit v1.2.3
