From fcf2d428e4a4e4930dbef8eb55f89528eaa84af8 Mon Sep 17 00:00:00 2001 From: Daniel Dunbar Date: Mon, 25 Jan 2010 00:44:02 +0000 Subject: ASTUnit: Don't check that input files exist when parsing ASTs from the command line -- they may be remapped (fake) files. This is useful for testing parsing entirely from memory. llvm-svn: 94395 --- clang/lib/Driver/Driver.cpp | 11 +++++------ 1 file changed, 5 insertions(+), 6 deletions(-) (limited to 'clang/lib/Driver/Driver.cpp') diff --git a/clang/lib/Driver/Driver.cpp b/clang/lib/Driver/Driver.cpp index 852a018e10f..62c2d12cd3b 100644 --- a/clang/lib/Driver/Driver.cpp +++ b/clang/lib/Driver/Driver.cpp @@ -50,8 +50,8 @@ Driver::Driver(llvm::StringRef _Name, llvm::StringRef _Dir, Name(_Name), Dir(_Dir), DefaultHostTriple(_DefaultHostTriple), DefaultImageName(_DefaultImageName), Host(0), - CCCIsCXX(false), CCCEcho(false), CCCPrintBindings(false), - CCCGenericGCCName("gcc"), CCCUseClang(true), + CCCGenericGCCName("gcc"), CCCIsCXX(false), CCCEcho(false), + CCCPrintBindings(false), CheckInputsExist(true), CCCUseClang(true), CCCUseClangCXX(true), CCCUseClangCPP(true), CCCUsePCH(true), SuppressMissingInputWarning(false) { if (IsProduction) { @@ -579,10 +579,9 @@ void Driver::BuildActions(const ArgList &Args, ActionList &Actions) const { Ty = InputType; } - // Check that the file exists.
