Chris Lattner d99bd52c73 Eli points out that we really must diagnose "void* > 0" as an extension.
Explicitly add it as an EXTENSION instead of an EXTWARN so that it only
comes out with -pedantic.  Thanks Eli!

Fariborz Jahanian a83c016d22 Type of a ?: expression whose either expression is a built-in 'id'
type is 'id' type.

Chris Lattner f8344dbfdd tweak some pointer sema checking stuff (which was added to implement PR4175) to
avoid emitting a warning on "someptr > 0".  This is obviously questionable (they 
could use != instead) but is reasonable, and the warning "ordered comparison 
between pointer and integer" didn't make a ton of sense because 0 is a valid 
null pointer constant.

Just silence the warning in this case, it is unlikely to indicate a bug.

Douglas Gregor 97628d6a4c Implement support for calling member function templates, which involves:
- Allowing one to name a member function template within a class
  template and on the right-hand side of a member access expression.
  - Template argument deduction for calls to member function templates.
  - Registering specializations of member function templates (and
  finding them later).

Patch by Enea Zaffanella, with some simplifications/corrections to
isPromotableBitField by me.

Eli Friedman 5ae98ee006 Make integer promotions work correctly on PIC16 and other platforms
where sizeof(short) == sizeof(int).  Move UsualArithmeticConversionsType 
out of Sema, since it was only there as a historical artifact.  Patch by 
Enea Zaffanella.

Fariborz Jahanian 88cc2340de Renamed ObjCKVCRefExpr to ObjCImplctSetterGetterRefExpr.
Removed an unnecessary loop to get to setters incoming
argument. Added DoxyGen comments. Still more work
to do in this area (WIP).

David Chisnall 9f57c29053 Initial patch to support definitions of id and Class from headers in Objective-C code.
This currently breaks test/SemaObjC/id-isa-ref.m and issues some spurious warnings when you attempt to assign a struct objc_class* value to a Class variable.  The test case probably should fail as it's written, because without the definition of Class the compiler should not assume struct objc_class* is a valid receiver type, but it's left broken because it would be nice if we could get that passing too for the special case of isa.

Approved by snaroff.

Eli Friedman da8d4def72 Don't perform integer promotions on the operand to a cast; this

casts to vector types. Patch by Enea Zaffanella.

Addresses Eli's patch feedback re: ugly cast code

Updates all postfix operators to remove ParenListExprs.  While this is awful,
no better solution (say, in the parser) is obvious to me.  Better solutions
welcome.

Nate Begeman a96114ed08 AltiVec-style vector initializer syntax, vec4 a = (vec4)(a, b, c, d);
In addition to being defined by the AltiVec PIM, this is also the vector
initializer syntax used by OpenCL, so that vector literals are compatible
with macro arguments.

Ted Kremenek c23c7e6a51 Change uses of:
Type::getAsReferenceType() -> Type::getAs<ReferenceType>()
  Type::getAsRecordType() -> Type::getAs<RecordType>()
  Type::getAsPointerType() -> Type::getAs<PointerType>()
  Type::getAsBlockPointerType() -> Type::getAs<BlockPointerType>()
  Type::getAsLValueReferenceType() -> Type::getAs<LValueReferenceType>()
  Type::getAsRValueReferenceType() -> Type::getAs<RValueReferenceType>()
  Type::getAsMemberPointerType() -> Type::getAs<MemberPointerType>()
  Type::getAsReferenceType() -> Type::getAs<ReferenceType>()
  Type::getAsTagType() -> Type::getAs<TagType>()
  
And remove Type::getAsReferenceType(), etc.

This change is similar to one I made a couple weeks ago, but that was partly
reverted pending some additional design discussion. With Doug's pending smart
pointer changes for Types, it seemed natural to take this approach.

A template name can refer to a set of overloaded function
templates. Model this in TemplateName, which can now refer to an
OverloadedFunctionDecl that contains function templates. This removes
an unspeakable hack in Sema::isTemplateName.

Douglas Gregor a6ef8f0813 Template instantiation for static data members that are defined out-of-line.
Note that this also fixes a bug that affects non-template code, where we 
were not treating out-of-line static data members are "file-scope" variables,
and therefore not checking their initializers.

- Sema::ConvertDeclSpecToType(): Replace a couple FIXME's with an important comment/example.
- Sema::GetTypeForDeclarator(): Get the protocol's from the interface, NOT the declspec (to support the following C typedef idiom: "typedef C<P> T; T *obj").
- Sema::ObjCQualifiedIdTypesAreCompatible(): Removed some dead code.
- ASTContext::getObjCEncodingForTypeImpl(): Some minor cleanups.
