From 7acd886ecfa0adc8a14476eafe8cf1fa981cfe18 Mon Sep 17 00:00:00 2001 From: Rafael Espindola Date: Wed, 11 Jun 2014 19:05:50 +0000 Subject: Use std::error_code instead of llvm::error_code. The idea of this patch is to turn llvm/Support/system_error.h into a transitional header that just brings in the erorr_code api to the llvm namespace. I will remove it shortly afterwards. The cases where the general idea needed some tweaking: * std::errc is a namespace in msvc, so we cannot use "using std::errc". I could add an #ifdef, but there were not that many uses, so I just added std:: to them in this patch. * Template specialization had to be moved to the std namespace in this patch set already. * The msvc implementation of default_error_condition doesn't seem to provide the same transformations as we need. Not too surprising since the standard doesn't actually say what "equivalent" means. I fixed the problem by keeping our old mapping and using it at error_code construction time. Despite these shortcomings I think this is still a good thing. Some reasons: * The different implementations of system_error might improve over time. * It removes 925 lines of code from llvm already. * It removes 6313 bytes from the text segment of the clang binary when it is built with gcc and 2816 bytes when building with clang and libstdc++. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210687 91177308-0d34-0410-b5e6-96231b3b80d8 --- unittests/Transforms/DebugIR/DebugIR.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'unittests/Transforms/DebugIR') diff --git a/unittests/Transforms/DebugIR/DebugIR.cpp b/unittests/Transforms/DebugIR/DebugIR.cpp index 49ea09f7c6..5860e31b9d 100644 --- a/unittests/Transforms/DebugIR/DebugIR.cpp +++ b/unittests/Transforms/DebugIR/DebugIR.cpp @@ -58,7 +58,7 @@ bool removeIfExists(StringRef Path) { // This is an approximation, on error we don't know in general if the file // existed or not. llvm::error_code EC = sys::fs::remove(Path, false); - return EC != llvm::errc::no_such_file_or_directory; + return EC != std::errc::no_such_file_or_directory; } char * current_dir() { -- cgit v1.2.3
