Update all tests other than Driver/std.cpp to use -std=c++11 rather than -std=c++0x. Patch by Ahmed Charles! llvm-svn: 141900 2011-10-14 06:29:44 +08:00			`// RUN: %clang_cc1 -fsyntax-only -verify -std=c++11 %s`
Add Parser support for C++0x literal operators ('operator "" i'). DeclarationName can't handle them yet, so right now Parser just errors out on them. llvm-svn: 90027 2009-11-28 12:44:28 +08:00
Implement semantic checking for C++ literal operators. This now rejects literal operators that don't meet the requirements. Templates are not yet checked for. llvm-svn: 93315 2010-01-13 17:01:02 +08:00			`void operator "" (const char *); // expected-error {{expected identifier}}`
Implement C++11 [lex.ext]p10 for string and character literals: a ud-suffix not starting with an underscore is ill-formed. Since this rule rejects programs that were using <inttypes.h>'s macros, recover from this error by treating the ud-suffix as a separate preprocessing-token, with a DefaultError ExtWarn. The approach of treating such cases as two tokens is under discussion for standardization, but is in any case a conforming extension and allows existing codebases to keep building while the committee makes up its mind. Reword the warning on the definition of literal operators not starting with underscores (which are, strangely, legal) to more explicitly state that such operators can't be called by literals. Remove the special-case diagnostic for hexfloats, since it was both triggering in the wrong cases and incorrect. llvm-svn: 152287 2012-03-08 10:39:21 +08:00			`void operator "k" foo(const char *); // \`
