2009-10-20Remove default argument for ImpCastExprToType. Add appropriate argument Eli Friedman
to all callers. Switch a few other users of CK_Unknown to proper cast kinds. Note that there are still some situations where we end up with CK_Unknown; they're pretty easy to find with grep. There are still a few missing conversion kinds, specifically pointer/int/float->bool and the various combinations of real/complex float/int->real/complex float/int. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84623 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-30When overload resolution fails for an overloaded operator, show theDouglas Gregor
overload candidates (but not the built-in ones). We still rely on the underlying built-in semantic analysis to produce the initial diagnostic, then print the candidates following that diagnostic. One side advantage of this approach is that we can perform more validation of C++'s operator overloading with built-in candidates vs. the semantic analysis for those built-in operators: when there are no viable candidates, we know to expect an error from the built-in operator handling code. Otherwise, we are not modeling the built-in semantics properly within operator overloading. This is checked as: assert(Result.isInvalid() && "C++ binary operator overloading is missing candidates!"); if (Result.isInvalid()) PrintOverloadCandidates(CandidateSet, /*OnlyViable=*/false); The assert() catches cases where we're wrong in a +Asserts build. The "if" makes sure that, if this happens in a production clang (-Asserts), we still build the proper built-in operator and continue on our merry way. This is effectively what happened before this change, but we've added the assert() to catch more flies. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83175 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-25Fix checking for a null pointer constant when the expression itself isDouglas Gregor
value-dependent. Audit (and fixed) all calls to Expr::isNullPointerConstant() to provide the correct behavior with value-dependent expressions. Fixes PR5041 and a crash in libstdc++ <locale>. In the same vein, properly compute value- and type-dependence for ChooseExpr. Fixes PR4996. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82748 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-24Refactor the representation of qualifiers to bring ExtQualType out of theJohn McCall
Type hierarchy. Demote 'volatile' to extended-qualifier status. Audit our use of qualifiers and fix a few places that weren't dealing with qualifiers quite right; many more remain. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82705 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-22Fix a regression in accessing class getter using the dot-syntaxFariborz Jahanian
notation. There is still an issue accessing field of a 'Class''s isa in legacy code using dot field access notation (as noted in the test case) but unrelated to this patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82555 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-22Implement code completion within a function call, triggered after theDouglas Gregor
opening parentheses and after each comma. We gather the set of visible overloaded functions, perform "partial" overloading based on the set of arguments that we have thus far, and return the still-viable results sorted by the likelihood that they will be the best candidate. Most of the changes in this patch are a refactoring of the overloading routines for a function call, since we needed to separate out the notion of building an overload set (common to code-completion and normal semantic analysis) and then what to do with that overload set. As part of this change, I've pushed explicit template arguments into a few more subroutines. There is still much more work to do in this area. Function templates won't be handled well (unless we happen to deduce all of the template arguments before we hit the completion point), nor will overloaded function-call operators or calls to member functions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82549 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-21Change all the Type::getAsFoo() methods to specializations of Type::getAs().John McCall
Several of the existing methods were identical to their respective specializations, and so have been removed entirely. Several more 'leaf' optimizations were introduced. The getAsFoo() methods which imposed extra conditions, like getAsObjCInterfacePointerType(), have been left in place. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82501 91177308-0d34-0410-b5e6-96231b3b80d8
