Add driver flags -ftrigraphs, -fno-trigraphs. -trigraphs is now an alias for -ftrigraphs. -fno-trigraphs makes it possible to explicitly disable trigraphs, which couldn't be done before. clang -std=c++11 -fno-trigraphs now builds without GNU extensions, but with trigraphs disabled. Previously, trigraphs were only disabled in GNU modes or with -std=c++1z. Make the new -f flags the cc1 interface too. This requires changing -trigraphs to -ftrigraphs in a few cc1 tests.

In Lexer::getCharAndSizeSlow[NoWarn] make sure we don't go over the end of the buffer when the end of the buffer is immediately after an escaped newline. Fixes http://llvm.org/PR10153. llvm-svn: 147091 2011-12-22 04:19:55 +08:00

In Lexer::getCharAndSizeSlow[NoWarn] if we come up against \<newline><newline> don't consume the second newline. Thanks to David Blaikie for pointing out the crash! llvm-svn: 147138 2011-12-22 12:38:07 +08:00
