- Currently CodeGen always returns a conservative value for this (-1
   or 0 depending on the context).

Highlights...

- 4 new AST nodes, BlockExpr, BlockStmtExpr, BlockExprExpr, BlockDeclRefExpr.
- Sema::ActOnBlockStart(), ActOnBlockError(), ActOnBlockStmtExpr(), ActOnBlockExprExpr(), ActOnBlockReturnStmt().

Next steps...

- hack Sema::ActOnIdentifierExpr() to deal with block decl refs.
- add attribute handler for byref decls.
- add test cases.

llvm-svn: 55710

 - Add ObjCMethodDecl::createImplicitParams.
 - Remove ObjCMethodDecl::set{Self,Cmd}Decl
 - Remove Sema::CreateImplicitParameter

No (intended) functionality change.

-The Parser calls a new "ActOnCXXTypeConstructExpr" action.
-Sema, depending on the type and expressions number:
   -If the type is a class, it will treat it as a class constructor. [TODO]
   -If there's only one expression (i.e. "int(0.5)" ), creates a new "CXXFunctionalCastExpr" Expr node
   -If there are no expressions (i.e "int()" ), creates a new "CXXZeroInitValueExpr" Expr node.

llvm-svn: 55177

 - UsualUnaryConversions takes an Expr *& and may modify its argument,
   this broke when it was refactored into Sema::CheckCastTypes. This
   meant that we were missing implicit casts in some places.
 - Seems pretty sad that this got through our tests.

llvm-svn: 55039

Move the type checking that Sema::ActOnCastExpr does into a new Sema::CheckCastTypes function so that it can be reused.

llvm-svn: 54852

 - 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 {Decl.h,DeclObjC.h,IdentifierTable.h} from Expr.h
 - Moved Sema::getCurMethodDecl() out of line (dependent on
   ObjCMethodDecl via dyn_cast).

llvm-svn: 54629

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

llvm-svn: 54625

Cleanup from yesterday...make isTentativeDefinition() a static helper function (no need for it to be part of the Sema API).

llvm-svn: 54613

llvm-svn: 54605

Passing right brace location to ActOnFinishCXXClassDef is redundant, since it gets passed to ActOnFinishCXXMemberSpecification too.

llvm-svn: 54567

- Move checking from MergeVarDecl->FinializeDeclaratorGroup. Since MergeVarDecl is called before the initializer is attacted, it can't be done there (this removes a long standing FIXME).
- Add Sema::isTentativeDefinition() and Sema::CheckForFileScopedRedefinitions().
- Remove FIXME's and touch-up test case.

Still some more work to do (forthcoming)...

llvm-svn: 54533

  ActOnDeclarator.

llvm-svn: 54353

 - ActOnDeclarator now takes an additional parameter which is the
   AsmLabel if used. Its unfortunate that this bubbles up this high,
   but we cannot just lump it in as an attribute without mistakenly
   *accepting* it as an attribute.
 - The actual asm-label itself is, however, encoded as an AsmLabelAttr
   on the FunctionDecl.
 - Slightly improved parser error recovery on malformed asm-labels.
 - CodeGen support still missing...

No functionality change.

last client of the old ParseObjCProtocolReferences, so it also removes it.

of a specific smallvector size.

Fix protocol lists to pass down proper location info, so we get diagnostics
like this:

t.m:3:35: error: cannot find protocol definition for 'NSCopying', referenced by 'NSWhatever'
@interface NSWhatever : NSObject <NSCopying>
                                  ^

instead of this:

t.m:3:44: error: cannot find protocol definition for 'NSCopying', referenced by 'NSWhatever'
@interface NSWhatever : NSObject <NSCopying>
                                           ^


Add a new IdentifierLocPair typedef which is just a pair<IdentifierInfo*, SourceLocation>

llvm-svn: 53883

llvm-svn: 53821

Add some code to handle vector comparisons, which is the language side
of the llvm vicmp/vfcmp instructions.  Also make the vector-vector and
vector-scalar asign checks a bit more sane under the presence of lax vector
conversions.

static functions instead of methods on sema.

llvm-svn: 52880

anyway, so there is no real loss here.  Start making attribute processing
methods static functions instead of methods on Sema.

llvm-svn: 52879

decl attributes out of the various places they can hide.  This makes
us correctly reject things like this:

t.c:2:22: error: mode attribute only supported for integer and floating-point types
  int **__attribute((mode(HI)))* i32;
                     ^

because you can't make a pointer be HImode.

to work list the rest of the attr handlers.  Also, rename
it to HandleVectorSizeAttribute to match its attr name.
No functionality change.

llvm-svn: 52872

the single attribute they look at by reference instead of by pointer.
This is a subtle indicator that they take the specified attribute, not
a whole list of them.

This also make HandleExtVectorTypeAttribute work the same way as the rest
of the attributes, adds some comments etc. No functionality change.

llvm-svn: 52871

Replace CurFunctionDecl and CurMethodDecl with methods getCurFunctionDecl() and getCurMethodDecl() that return the appropriate Decl through CurContext.

llvm-svn: 52852

SemaDeclAttr, and do some cleanups.
