Use a single function for doing vararg argument promotion. Also, make sure to do the promotion before checking the type - fixes PR3340.

filters the decls seen by decl_iterator with two criteria: the dynamic
type of the declaration and a run-time predicate described by a member
function. This simplifies EnumDecl, RecordDecl, and ObjCContainerDecl
considerably. It has no measurable performance impact.

change the semantics.  Please correct this if the precedence was

instead of converting them to strings first.  This also fixes a
bunch of minor inconsistencies in the diagnostics emitted by clang
and adds a bunch of FIXME's to DiagnosticKinds.def.

llvm-svn: 59948

uses of getName() with uses of getDeclName().  This upgrades a bunch of
diags to take DeclNames instead of std::strings.

This also tweaks a couple of diagnostics to be cleaner and changes
CheckInitializerTypes/PerformInitializationByConstructor to pass
around DeclarationNames instead of std::strings.

llvm-svn: 59947

a new NamedDecl::getAsString() method.

Change uses of Selector::getName() to just pass in a Selector 
where possible (e.g. to diagnostics) instead of going through
an std::string.

This also adds new formatters for objcinstance and objcclass
as described in the dox.

llvm-svn: 59933

with implicit quotes around them.  This has a bunch of follow-on 
effects and requires tweaking to a whole lot of code.  This causes
a regression in two tests (xfailed) by causing it to emit things like:

  Line 10: duplicate interface declaration for category 'MyClass1' ('Category1')

instead of:

  Line 10: duplicate interface declaration for category 'MyClass1(Category1)'

I will fix this in a follow-up commit.

As part of this, I had to start switching stuff to use ->getDeclName() instead
of Decl::getName() for consistency.  This is good, but I was planning to do this
as an independent patch.  There will be several follow-on patches
to clean up some of the mess, but this patch is already too big.

just check for it when needed.  It doesn't incur real cost
in any hot paths.

llvm-svn: 59708

The core fix in Sema::ActOnClassMessage(). All the other changes have to do with passing down the SourceLocation for the receiver (to properly position the cursor when producing an error diagnostic).

llvm-svn: 59639

llvm-svn: 59609

__builtin_prefetch code to only emit one diagnostic per builtin_prefetch.
While this has nothing to do with the rest of the patch, the code seemed
like overkill when I was updating it.

llvm-svn: 59588

Missing special lookup rule in Sema::ActOnInstanceMessage().

llvm-svn: 59467

Add a new expression class, ObjCSuperExpr, to handle the Objective-C 'super'. Remove ObjCThis from PredefinedExpr

llvm-svn: 58698

Fix <rdar://problem/6191148> [sema] Objective-C method lookup (at global scope) fails to handle overloaded selectors properly.

Long standing bug in Sema::ActOnInstanceMessage(). We now warn when messaging an "id" with multiple method signatures in scope. The diags are a little verbose, however they can be streamlined if necessary. 

llvm-svn: 56843

llvm-svn: 56791

Fix <rdar://problem/6252129> implementation of method in category doesn't effectively declare it for methods below.

llvm-svn: 56771

(1) Additional arguments to variadic methods should have default
promotions applied.

(2) Additional arguments to non-variadic methods were allowed.

llvm-svn: 56084

no method declaration was found.
 - This was allowing arrays to pass "by value" among other things.

Add assert in CodeGen that arguments cannot have array type.

llvm-svn: 56080

CheckMessageArgumentTypes.
 - No functionality change.

llvm-svn: 56079

 - Added as private members for each because it is not clear where to
   put the common definition. Perhaps the IdentifierInfos all of these
   "pseudo-keywords" should be collected into one place (this would
   KnownFunctionIDs and Objective-C property IDs, for example).

Remove Token::isNamedIdentifier.
 - There isn't a good reason to use strcmp when we have interned
   strings, and there isn't a good reason to encourage clients to do
   so.

llvm-svn: 54794

 - Drop TokenKinds.h from Action.h
 - Move DeclSpec.h from Sema.h into individual Sema .cpp files

llvm-svn: 54625

llvm-svn: 54605

ASTContext::getCanonicalType instead (PR2189)

llvm-svn: 54105

(a) removes a bogus warning.
(b) removes an undesirable usage of the ObjCMessageExpr constructor that takes an IdentifierInfo * (which I will abolish).

llvm-svn: 54042

This fixes a critical rewriter bug (<rdar://problem/6096760> clang ObjC rewriter: 'self' not expected value in class method called with 'super').

Also added a couple FIXME's since I'm not happy with my fix to Sema. It would be nicer if the super handling for class/instance messages was the same (based on PreDefinedExpr).
