2009-11-05Implement the conditional-operator part of -Wsign-compare. TurnJohn McCall
DiagnoseSignCompare into Sema::CheckSignCompare and call it from more places. Add some enumerator tests. These seem to expose some oddities in the types we're converting C++ enumerators to; in particular, they're converting to unsigned before int, which seems to contradict 4.5 [conv.prom] p2. Note to self: stop baiting Doug in my commit messages. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86128 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-04Implement support for parsing dependent template-ids that refer toDouglas Gregor
overloaded operators, e.g., p->template operator+<T>() git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85989 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-03Parsing and semantic analysis for template-ids that name overloadedDouglas Gregor
operators, e.g., operator+<int> which now works in declarators, id-expressions, and member access expressions. This commit only implements the non-dependent case, where we can resolve the template-id to an actual declaration. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85966 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-03Replace the code that parses member access expressions after "." orDouglas Gregor
"->" with a use of ParseUnqualifiedId. Collapse ActOnMemberReferenceExpr, ActOnDestructorReferenceExpr (both of them), ActOnOverloadedOperatorReferenceExpr, ActOnConversionOperatorReferenceExpr, and ActOnMemberTemplateIdReferenceExpr into a single, new action ActOnMemberAccessExpr that does the same thing more cleanly (and can keep more source-location information). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85930 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-03Introduce a new class, UnqualifiedId, that provides a parsedDouglas Gregor
representation of a C++ unqualified-id, along with a single parsing function (Parser::ParseUnqualifiedId) that will parse all of the various forms of unqualified-id in C++. Replace the representation of the declarator name in Declarator with the new UnqualifiedId class, simplifying declarator-id parsing considerably and providing more source-location information to Sema. In the future, I hope to migrate all of the other unqualified-id-parsing code over to this single representation, then begin to merge actions that are currently only different because we didn't have a unqualified notion of the name in the parser. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@85851 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-25In objc mode, every identifier in a cast expression was using doing aChris Lattner
type looking using getTypeName() and every property access was using NextToken() to do lookahead to see if the identifier is followed by a '.'. Rearrange this code to not need lookahead and only do the type lookup if we have "identifier." in the token stream.
