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/g++.dg/tree-ssa/pr24231-3.C | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) create mode 100644 gcc/testsuite/g++.dg/tree-ssa/pr24231-3.C (limited to 'gcc/testsuite/g++.dg/tree-ssa/pr24231-3.C') diff --git a/gcc/testsuite/g++.dg/tree-ssa/pr24231-3.C b/gcc/testsuite/g++.dg/tree-ssa/pr24231-3.C new file mode 100644 index 000000000..a9ea58b11 --- /dev/null +++ b/gcc/testsuite/g++.dg/tree-ssa/pr24231-3.C @@ -0,0 +1,28 @@ +/* { dg-do compile } */ +/* { dg-options "-O2" } */ +/* PRE testcase for PR 24231, problem with PRE coalescing abnormal phis. */ +struct MemoryManager { + virtual void deallocate() = 0; +}; +struct XalanVector { + ~XalanVector() { + m_memoryManager->deallocate(); + } + void swap(XalanVector& theOther) { + MemoryManager* const theTempManager = m_memoryManager; + m_memoryManager = theOther.m_memoryManager; + theOther.m_memoryManager = theTempManager; + theOther.m_size = 0; + } + void push_back() { + XalanVector theTemp(*this); + theTemp.push_back(); + swap(theTemp); + } + MemoryManager* m_memoryManager; + int m_size; +}; +void f(void) { + XalanVector tempVector; + tempVector.push_back(); +} -- cgit v1.2.3
