DeLesley Hutchins	5b330db270	Bugfix: bogus warning -- "invalid use of non-static data member", ... when a class is forward declared, and the reference to the data member in question does not occur within a method body. llvm-svn: 151413	2012-02-25 00:11:55 +00:00
Richard Smith	e434590bd9	Change the diagnostics which said 'accepted as an extension' to instead say ... 'is an extension'. The former is inappropriate and confusing when building with -Werror/-pedantic-errors. llvm-svn: 147357	2011-12-29 21:57:33 +00:00
Richard Smith	d0b4dd656d	constexpr handling improvements. Produce detailed diagnostics when a 'constexpr' ... variable is initialized by a non-constant expression, and pass in the variable being declared so that earlier-initialized fields' values can be used. Rearrange VarDecl init evaluation to make this possible, and in so doing fix a long-standing issue in our C++ constant expression handling, where we would mishandle cases like: extern const int a; const int n = a; const int a = 5; int arr[n]; Here, n is not initialized by a constant expression, so can't be used in an ICE, even though the initialization expression would be an ICE if it appeared later in the TU. This requires computing whether the initializer is an ICE eagerly, and saving that information in PCH files. llvm-svn: 146856	2011-12-19 06:19:21 +00:00
Richard Smith	9ca5c42582	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	2011-10-13 22:29:44 +00:00
Richard Smith	7b729cdbff	Suggest adding 'constexpr' if the GNU extension for in-class initializers for static const float members is used in C++11 mode. ... llvm-svn: 140828	2011-09-30 00:33:19 +00:00
Richard Smith	256336d9ab	Mark the ExtWarn for in-class initialization of static const float members as a GNU extension. Don't extend the scope of this extension to all literal types in C++0x mode. ... llvm-svn: 140820	2011-09-29 23:18:34 +00:00
Richard Smith	ee6311df69	In C++0x, static const volatile data members cannot be initialized in-class. ... llvm-svn: 140809	2011-09-29 21:28:14 +00:00
