From 189f231a4b58a604320fb8c839689578d3ddb5c9 Mon Sep 17 00:00:00 2001 From: Benjamin Kramer Date: Sat, 4 Aug 2012 09:47:02 +0000 Subject: Postpone the deletion of the old name in StructType::setName to allow using a slice of the old name. Fixes PR13522. Add a rudimentary unit test to exercise the behavior. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161296 91177308-0d34-0410-b5e6-96231b3b80d8 --- unittests/VMCore/TypesTest.cpp | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) create mode 100644 unittests/VMCore/TypesTest.cpp (limited to 'unittests') diff --git a/unittests/VMCore/TypesTest.cpp b/unittests/VMCore/TypesTest.cpp new file mode 100644 index 0000000..0416643 --- /dev/null +++ b/unittests/VMCore/TypesTest.cpp @@ -0,0 +1,30 @@ +//===- llvm/unittest/VMCore/TypesTest.cpp - Type unit tests ---------------===// +// +// The LLVM Compiler Infrastructure +// +// This file is distributed under the University of Illinois Open Source +// License.
