Put warning about makeing a string writable into its own deprecated diagnostics group so it can be turned off selectively. // rdar://8827606 llvm-svn: 122967 2011-01-07 02:45:19 +08:00			`// RUN: %clang_cc1 -fsyntax-only -Wno-deprecated-writable-strings -verify %s`
-fwritable-strings should silence warnings about the deprecated string -literal to char* conversion. Make it so. llvm-svn: 127586 2011-03-15 00:13:32 +08:00			`// RUN: %clang_cc1 -fsyntax-only -fwritable-strings -verify %s`
GCC overloads -Wwrite-strings just to make it extra confusing. While it changes language semantics in C and ObjC (which Clang has supported for a while), in C++ it's the name used for Clang's -Wdeprecated-writable-strings. Clang's name is at least less overloaded if still confusing (the string isn't writable, we just allow converting to a non-const pointer without warning), so I've left it in place and made the GCC name an alias for compatibility. With this I've implemented all the aspects of GCC's -Wwrite-strings I've encountered which didn't work with Clang. llvm-svn: 130052 2011-04-23 14:54:44 +08:00			`// RUN: %clang_cc1 -fsyntax-only -Wno-write-strings -verify %s`
Add -Wdeprecated-writable-string in C++ to -Wc++11-compat, since it's ill-formed in C++11. llvm-svn: 194736 2013-11-15 06:22:31 +08:00			`// RUN: %clang_cc1 -fsyntax-only -Werror=c++11-compat -verify %s -DERROR`
