Revert r148138; it's causing test failures. llvm-svn: 148141 2012-01-14 05:33:06 +08:00			`// RUN: %clang -ccc-host-triple x86_64-unknown-unknown \`
Driver: Add support for a new -nostdlibinc option. - This disables the system include directories, but not the compiler builtin directories. Useful for projects that want to use things like the intrinsic headers, but are otherwise freestanding. - I'm willing to reconsider the option naming, I also considered providing an explicit -builtinc (which would match -nobuiltininc), but this is more consistent with existing options. llvm-svn: 141692 2011-10-12 02:20:16 +08:00			`// RUN: -nostdlibinc -ffreestanding -fsyntax-only %s`
