# 9588a02b	30-Jan-2013	Jordan Rose <jordan_rose@apple.com>	Fix comment in test/Lexer/utf8-invalid.c for updates in r173959. llvm-svn: 173961
# f649795f	30-Jan-2013	Jordan Rose <jordan_rose@apple.com>	Fix r173881 to properly skip invalid UTF-8 characters in raw lexing and -E. This caused hangs as we processed the same invalid byte over and over. <rdar://problem/13115651> llvm-svn: 173959
# 7f43ddda	24-Jan-2013	Jordan Rose <jordan_rose@apple.com>	Handle universal character names and Unicode characters outside of literals. This is a missing piece for C99 conformance. This patch handles UCNs by adding a '\\' case to LexTokenInternal and LexId Handle universal character names and Unicode characters outside of literals. This is a missing piece for C99 conformance. This patch handles UCNs by adding a '\\' case to LexTokenInternal and LexIdentifier -- if we see a backslash, we tentatively try to read in a UCN. If the UCN is not syntactically well-formed, we fall back to the old treatment: a backslash followed by an identifier beginning with 'u' (or 'U'). Because the spelling of an identifier with UCNs still has the UCN in it, we need to convert that to UTF-8 in Preprocessor::LookUpIdentifierInfo. Of course, valid code that does not use UCNs will see only a very minimal performance hit (checks after each identifier for non-ASCII characters, checks when converting raw_identifiers to identifiers that they do not contain UCNs, and checks when getting the spelling of an identifier that it does not contain a UCN). This patch also adds basic support for actual UTF-8 in the source. This is treated almost exactly the same as UCNs except that we consider stray Unicode characters to be mistakes and offer a fixit to remove them. llvm-svn: 173369 show more ...
