From 6e5fcf18987022f1e54f0c0f06042fe59cc6d2a2 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Fri, 10 Dec 2004 20:10:23 +0000 Subject: [PATCH] New testcase that SCCP miscompiles. Luckily this is extremely unlikely to happen in practice, but IP-SCCP can trigger it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18773 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/Transforms/SCCP/2004-12-10-UndefBranchBug.ll | 11 +++++++++++ 1 file changed, 11 insertions(+) create mode 100644 test/Transforms/SCCP/2004-12-10-UndefBranchBug.ll diff --git a/test/Transforms/SCCP/2004-12-10-UndefBranchBug.ll b/test/Transforms/SCCP/2004-12-10-UndefBranchBug.ll new file mode 100644 index 00000000000..be6944ce002 --- /dev/null +++ b/test/Transforms/SCCP/2004-12-10-UndefBranchBug.ll @@ -0,0 +1,11 @@ +; RUN: llvm-as < %s | opt -sccp | llvm-dis | grep 'ret int 1' + +; This function definitely returns 1, even if we don't know the direction +; of the branch. + +int %foo() { + br bool undef, label %T, label %T +T: + %X = add int 0, 1 + ret int %X +}
