From 5a1a1856a4dfa1335d937437fade5c0bbab06560 Mon Sep 17 00:00:00 2001 From: David Majnemer Date: Sun, 6 Oct 2013 20:25:49 +0000 Subject: Windows: Add support for unicode command lines Summary: The MSVCRT deliberately sends main() code-page specific characters. This isn't too useful to LLVM as we end up converting the arguments to UTF-16 and subsequently attempt to use the result as, for example, a file name. Instead, we need to have the ability to access the Unicode command line and transform it to UTF-8. This has the distinct advantage over using the MSVC-specific wmain() function as our entry point because: - It doesn't work on cygwin. - It only work on MinGW with caveats and only then on certain versions. - We get to keep our entry point as main(). :) N.B. This patch includes fixes to other parts of lib/Support/Windows s.t. we would be able to take advantage of getting the Unicode paths. E.G. clang spawning clang -cc1 would want to give it Unicode arguments.
