From 8fa83afb83ea16e768db8f515658b213a606863e Mon Sep 17 00:00:00 2001 From: Justin Bogner Date: Wed, 16 Jul 2014 08:18:58 +0000 Subject: [PATCH] unittests: Actually test reverse iterators in Path tests This re-enables some #if 0'd code (since 2010) in the Path unittests and makes at least a weak effort at testing sys::path's rbegin/rend. This change was inspired by some test failures near uses of rbegin and rend here: http://lab.llvm.org:8011/builders/clang-x86_64-linux-vg/builds/3209 The "valgrind was whining" comment looked promising in terms of a simpler to debug case of the same errors. However, it appears that the valgrind complaints the comment was referring to are distinct from the ones in the frontend, since this updated test isn't complaining for me under valgrind. In any case, the disabled tests weren't helping anybody. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@213125 91177308-0d34-0410-b5e6-96231b3b80d8 --- unittests/Support/Path.cpp | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/unittests/Support/Path.cpp b/unittests/Support/Path.cpp index cf2e1eed282..db85347e921 100644 --- a/unittests/Support/Path.cpp +++ b/unittests/Support/Path.cpp @@ -91,6 +91,7 @@ TEST(Support, Path) { paths.push_back("c:\\foo/"); paths.push_back("c:/foo\\bar"); + SmallVector ComponentStack; for (SmallVector::const_iterator i = paths.begin(), e = paths.end(); i != e; @@ -100,18 +101,17 @@ TEST(Support, Path) { ci != ce; ++ci) { ASSERT_FALSE(ci->empty()); + ComponentStack.push_back(*ci); } -#if 0 // Valgrind is whining about this. - outs() << " Reverse Iteration: ["; for (sys::path::reverse_iterator ci = sys::path::rbegin(*i), ce = sys::path::rend(*i); ci != ce; ++ci) { - outs() << *ci << ','; + ASSERT_TRUE(*ci == ComponentStack.back()); + ComponentStack.pop_back(); } - outs() << "]\n"; -#endif + ASSERT_TRUE(ComponentStack.empty()); path::has_root_path(*i); path::root_path(*i); -- 2.34.1
