Author: xiaobai Date: Mon Mar 4 13:36:49 2019 New Revision: 355341 URL: http://llvm.org/viewvc/llvm-project?rev=355341&view=rev Log: [build.py] Allow clang-cl to build files starting with '/U'
Summary: clang-cl tries to match cl's interface, and treats /U as "Removes a predefined macro" as cl does. When you feed clang-cl a file that begins with '/U' (e.g. /Users/xiaobai/foo.c), clang-cl will emit a warning and in some cases an error, like so: clang-9: warning: '/Users/xiaobai/foo.c' treated as the '/U' option [-Wslash-u-filename] clang-9: note: Use '--' to treat subsequent arguments as filenames clang-9: error: no input files If you're using clang-cl, make sure '--' is passed before the source file.
