Hi, the attached patch disables trigraphs by default in clang-cl mode. To do so, I'm renaming the cc1 trigraph flag to -ftrigraphs, and I'm adding a -fno-trigraphs flag. (This requires updating a handful of cc1 tests, and translating -trigraphs to -ftrigraphs in the driver.)
The driver grows parsing logic for /Zc:, everything other than trigraphs is ignored for now. (We probably want to implement at least /Zc:inline at some point, which is why I added parsing code for this instead of always sending -fno-trigraphs to cc1 in clang-cl mode.) Ok? Nico
