From 6bf104b165cec9c14dacf10bf3380eeb32c278d7 Mon Sep 17 00:00:00 2001 From: Hans Wennborg Date: Fri, 2 Aug 2013 21:20:27 +0000 Subject: Option parsing: recognize the special -- token Everything that comes after -- should be treated as a filename. This enables passing in filenames that would otherwise be conflated with command-line options. This is especially important for clang-cl which supports options starting with /, which are easily conflatable with Unix-style path names.
