From 93e3cfcf9906b8eac682844af2d040a4f086b711 Mon Sep 17 00:00:00 2001 From: Justin Bogner Date: Fri, 12 Dec 2014 23:12:27 +0000 Subject: [PATCH] Frontend: Canonicalize to native paths when dumping module dependencies Mixed path separators (ie, both / and \\) can mess up the sort order of the VFS map when dumping module dependencies, as was recently exposed by r224055 and papered over in r224145. Instead, we should simply use native paths for consistency. This also adds a TODO to add handling of .. in paths. There was some code for this before r224055, but it was untested and probably broken. llvm-svn: 224164 --- clang/lib/Frontend/ModuleDependencyCollector.cpp | 4 ++++ clang/test/Modules/dependency-dump.m | 10 +++++----- 2 files changed, 9 insertions(+), 5 deletions(-) diff --git a/clang/lib/Frontend/ModuleDependencyCollector.cpp b/clang/lib/Frontend/ModuleDependencyCollector.cpp index 1ac7e36..8e2ee55 100644 --- a/clang/lib/Frontend/ModuleDependencyCollector.cpp +++ b/clang/lib/Frontend/ModuleDependencyCollector.cpp @@ -63,6 +63,10 @@ std::error_code ModuleDependencyListener::copyToRoot(StringRef Src) { // We need an absolute path to append to the root.
