2013-04-21The 'constexpr implies const' rule for non-static member functions is gone inRichard Smith
C++1y, so stop adding the 'const' there. Provide a compatibility warning for code relying on this in C++11, with a fix-it hint. Update our lazily-written tests to add the const, except for those ones which were testing our implementation of this rule. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179969 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-31Improve 'failed template argument deduction' diagnostic for the case where weRichard Smith

2013-01-14Refactor to call ActOnFinishFullExpr on every full expression. TeachRichard Smith

2012-12-06Fix http://stackoverflow.com/questions/13521163Richard Smith
Don't require that, during template deduction, a template specialization type as a function parameter has at least as many template arguments as one used in a function argument (not even if the argument has been resolved to an exact type); the additional parameters might be provided by default template arguments in the template. We don't need this check, since we now implement [temp.deduct.call]p4 with an additional check after deduction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169475 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-13Promote the warning about extra qualification on a declaration from aDouglas Gregor

2012-09-07PR9023: A template template parameter whose template parameter list contains anRichard Smith
unexpanded parameter pack is a pack expansion. Thus, as with a non-type template parameter which is a pack expansion, it needs to be expanded early into a fixed list of template parameters. Since the expanded list of template parameters is not itself a parameter pack, it is permitted to appear before the end of the template parameter list, so also remove that restriction (for both template template parameter pack expansions and non-type template parameter pack expansions). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163369 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-10Check access to friend declarations. There's a number of differentJohn McCall
things going on here that were problematic: - We were missing the actual access check, or rather, it was suppressed on account of being a redeclaration lookup. - The access check would naturally happen during delay, which isn't appropriate in this case. - We weren't actually emitting dependent diagnostics associated with class templates, which was unfortunate. - Access was being propagated incorrectly for friend method declarations that couldn't be matched at parse-time. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161652 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-18PR13386: When matching up parameters between a function template declarationRichard Smith
and a function template instantiation, if there's a parameter pack in the declaration and one at the same place in the instantiation, don't assume that the pack wasn't expanded -- it may have expanded to nothing. Instead, go ahead and check whether the parameter pack was expandable. We can do this as a side-effect of the work we'd need to do anyway, to find how many parameters were produced. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160416 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-15Improve some of the conversion warnings to fire on conversion to bool.David Blaikie
Moves the bool bail-out down a little in SemaChecking - so now -Wnull-conversion and -Wliteral-conversion can fire when the target type is bool.

2012-05-07Change how we suppress access control in explicit instantiationsJohn McCall
so that we actually accumulate all the delayed diagnostics. Do this so that we can restore those diagnostics to good standing if it turns out that we were wrong to suppress, e.g. if the tag specifier is actually an elaborated type specifier and not a declaration. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@156291 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-16Implement the last part of C++ [class.mem]p2, delaying the parsing ofDouglas Gregor
exception specifications on member functions until after the closing '}' for the containing class. This allows, for example, a member function to throw an instance of its own class.

2012-04-05Enable warn_impcast_literal_float_to_integer by default.David Blaikie
This diagnostic seems to be production ready, it's just an oversight that it wasn't turned on by default. The test changes are a bit of a mixed bag. Some tests that seemed like they clearly didn't need to use this behavior have been modified not to use it. Others that I couldn't be sure about, I added the necessary expected-warnings to. It's possible the diagnostic message could be improved to make it clearer that this warning can be suppressed by using a value that won't lose precision when converted to the target type (but can still be a floating point literal, such as "bool b = 1.0;"). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154068 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-11Represent C++ direct initializers as ParenListExprs before semantic analysisSebastian Redl
instead of having a special-purpose function. - ActOnCXXDirectInitializer, which was mostly duplication of AddInitializerToDecl (leading e.g. to PR10620, which Eli fixed a few days ago), is dropped completely. - MultiInitializer, which was an ugly hack I added, is dropped again. - We now have the infrastructure in place to distinguish between int x = {1}; int x({1}); int x{1}; -- VarDecl now has getInitStyle(), which indicates which of the above was used. -- CXXConstructExpr now has a flag to indicate that it represents list- initialization, although this is not yet used. - InstantiateInitializer was renamed to SubstInitializer and simplified. - ActOnParenOrParenListExpr has been replaced by ActOnParenListExpr, which always produces a ParenListExpr. Placed that so far failed to convert that back to a ParenExpr containing comma operators have been fixed. I'm pretty sure I could have made a crashing test case before this. The end result is a (I hope) considerably cleaner design of initializers. More importantly, the fact that I can now distinguish between the various initialization kinds means that I can get the tricky generalized initializer test cases Johannes Schaub supplied to work. (This is not yet done.) This commit passed self-host, with the resulting compiler passing the tests. I hope it doesn't break more complicated code.
