[cdt-dev] Changes to the AST in CDT 7.0

["Schorn, Markus" <Markus.Schorn@xxxxxxxxxxxxx>]

Hi,
I have summarized changes in the AST representation of this release and
put them on wiki: http://wiki.eclipse.org/CDT/planning/7.0 

The LR Parsers use some AST-constructs that are now deprecated. It'd be
good to 
update the parsers before the 7.0 release.

Below you find what I camp up with.

Chages to the AST:
==================

Function calls:
   * The arguments of a function call are represented as
IASTInitializerClause[].
   * For function calls with more than one argument the ast no longer
contains
     an IASTExpressionList.

Initializers:
   * An equals initializer is represented with an IASTEqualsInitializer
node.
   * The member of an IASTInitializerList is no longer wrapped in an
     IASTInitializerExpression.

Enumerations:
   * A new scope kind for enumeration scope (EScopeKind.eEnumeration)
has been added.
   * IBinding getOwner() for enumerators returns an enum-scope.

Functional casts and compound literals:
   * Uniformly represented as ICPPASTSimpleTypeConstructorExpression.
   * The interface ICPPASTTypenameExpression is no longer used.

C++ and Gnu specific constants:
   * Constants have been pulled up into the following base interfaces:
     IASTDeclSpecifier, IASTSimpleDeclSpecifier, IBasicType.
   * IGPPASTDeclSpecifier, IGCCASTSimpleDeclSpecifier,
IGPPASTSimpleDeclSpecifier
     and IGPPBasicType are no longer used.
