Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). llvm-svn: 91446 2009-12-15 20:14:24 +00:00			`// RUN: %clang_cc1 -fsyntax-only -verify -std=c++0x %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 04:44:28 +00:00
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 09:01:02 +00:00			`void operator "" (const char *); // expected-error {{expected identifier}}`
Allow C99 hexfloats in C++0x mode. This change resolves the standards collision between C99 hexfloats and C++0x user-defined literals by giving C99 hexfloats precedence. Also, warning about user-defined literals that conflict with hexfloats and those that have names that are reserved by the implementation. Fixes <rdar://problem/9940194>. llvm-svn: 138839 2011-08-30 22:40:35 +00:00			`void operator "k" foo(const char *); // expected-error {{string literal after 'operator' must be '""'}} \`
			`// expected-warning{{user-defined literal with suffix 'foo' is preempted by C99 hexfloat extension}}`
			`void operator "" tester (const char *); // expected-warning{{user-defined literal with suffix 'tester' is preempted by C99 hexfloat extension}}`
