2010-10-21Implement the integral promotion rules for the C++0x char16_t andDouglas Gregor
char32_t character types and enable built-in overloaded operator candidates for these types. Fixes PR8432. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117038 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-15Add builtin conditional operator candidates for scoped enumerationDouglas Gregor
types, from Alp Toker! Fixes PR8344. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116549 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-13Teach the warning about unnamed/local types in template arguments toDouglas Gregor
actually walk the template argument type to find any unnamed/local types within it. Fixes PR6784. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116382 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-12Introduce support for emitting diagnostics (warnings + their notes)Douglas Gregor
that are suppressed during template argument deduction. This change queues diagnostics computed during template argument deduction. Then, if the resulting function template specialization or partial specialization is chosen by overload resolution or partial ordering (respectively), we will emit the queued diagnostics at that point. This addresses most of PR6784. However, the check for unnamed/local template arguments (which existed before this change) is still only skin-deep, and needs to be extended to look deeper into types. It must be improved to finish PR6784. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116373 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-08Implement C++0x scoped enumerations, from Daniel Wallin! (and tweaked aDouglas Gregor

2010-09-29When performing template argument deduction of a function templateDouglas Gregor
against a function type, be sure to check the type of the resulting function template specialization against the desired function type after substituting the deduced/defaulted template arguments. Fixes PR8196. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@115086 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-28Don't warn with -Wbool-conversions if the user wrote an explicit cast like ↵Argyrios Kyrtzidis

2010-09-27Kill FunctionDecl's IsCopyAssignment bit; it duplicated what couldDouglas Gregor
already be determined by isCopyAssignmentOperator(), and was set too late in the process for all clients to see the appropriate value. Cleanup only; no functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114916 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-12Don't assert when attempting to take the address of an overloadedDouglas Gregor
function fails due to ambiguities in partial ordering of function templates. Fixes PR8033. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113725 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-12When performing overload resolution, only compare the final conversionDouglas Gregor
sequences for two conversion functions when in fact we are in the text of initialization by a user-defined conversion sequences. Fixes PR8034. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113724 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-12Implement the "note" in C++ [over.built]p1, which is actually meant toDouglas Gregor
be a semantic requirement that a built-in overloaded operator is not added to the overload set of there is already a user-defined overloaded operator with the same parameter types. Fixes PR8087. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113713 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-12Don't perform integral promotions from an incompletion enumerationDouglas Gregor
type. Fixes PR8089 in a slightly different way than had been suggested. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113711 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-09Eliminate the comma locations from all of the Sema routines that dealDouglas Gregor
with comma-separated lists. We never actually used the comma locations, nor did we store them in the AST, but we did manage to waste time during template instantiation to produce fake locations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113495 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-28Fix the memory leak of FloatingLiteral/IntegerLiteral.Argyrios Kyrtzidis
For large floats/integers, APFloat/APInt will allocate memory from the heap to represent these numbers. Unfortunately, when we use a BumpPtrAllocator to allocate IntegerLiteral/FloatingLiteral nodes the memory associated with the APFloat/APInt values will never get freed. I introduce the class 'APNumericStorage' which uses ASTContext's allocator for memory allocation and is used internally by FloatingLiteral/IntegerLiteral. Fixes rdar://7637185 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112361 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-27Propagate whether an id-expression is the immediate argument ofJohn McCall
an '&' expression from the second caller of ActOnIdExpression. Teach template argument deduction that an overloaded id-expression doesn't give a valid type for deduction purposes to a non-static member function unless the expression has the correct syntactic form. Teach ActOnIdExpression that it shouldn't try to create implicit member expressions for '&function', because this isn't a permitted form of use for member functions. Teach CheckAddressOfOperand to diagnose these more carefully. Some of these cases aren't reachable right now because earlier diagnostics interrupt them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112258 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-19We don't actually need to check the implicit object argument'sDouglas Gregor
conversion a second time for a conversion candidate (with the real acting context), because the only problems we would find are access or ambiguity issues that won't be diagnosed until we pick this candidate. Add a test case to prove it to myself. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111526 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-19Properly implement the part of C++ [over.match.funcs]p4 that treatsDouglas Gregor
conversion functions as if their acting context were the class that we're converting from (the implicit object argument's type). Retroactively tweaking the implicit conversion sequence, as we were trying to do before, breaks the invariants of that implicit conversion sequence (e.g., the types and conversions don't match up). Fixes <rdar://problem/8018274>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111520 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-18There is no pointer conversion between to similar types (i.e., sameDouglas Gregor

2010-08-11Improve our handling of user-defined conversions when computingDouglas Gregor
implicit conversion sequences. In particular, model the "standard conversion" from a class to its own type (or a base type) directly as a standard conversion in the normal path *without* trying to determine if there is a valid copy constructor. This appears to match the intent of C++ [over.best.ics]p6 and more closely matches GCC and EDG. As part of this, model non-lvalue reference initialization via user-defined conversion in overloading the same way we handle it in InitializationSequence, separating the "general user-defined conversion" and "conversion to compatible class type" cases. The churn in the overload-call-copycon.cpp test case is because the test case was originally wrong; it assumed that we should do more checking for copy constructors that we actually should, which affected overload resolution. Fixes PR7055. Bootstrapped okay. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110773 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-07Allow reference binding of a reference of Objective-C object type toDouglas Gregor
an lvalue of another, compatible Objective-C object type (e.g., a subclass). Introduce a new initialization sequence step kind to describe this binding, along with a new cast kind. Fixes PR7741. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110513 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-07Store inheritance paths after CastExprs instead of inside them.John McCall
This takes some trickery since CastExpr has subclasses (and indeed, is abstract). Also, smoosh the CastKind into the bitfield from Expr. Drops two words of storage from Expr in the common case of expressions which don't need inheritance paths. Avoids a separate allocation and another word of overhead in cases needing inheritance paths. Also has the advantage of not leaking memory, since destructors for AST nodes are never run. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110507 91177308-0d34-0410-b5e6-96231b3b80d8
