Detailed Description

PragmaHandler - Instances of this interface defined to handle the various pragmas that the language front-end uses.

Each handler optionally has a name (e.g. "pack") and the HandlePragma method is invoked when a pragma with that identifier is found. If a handler does not match any of the declared pragmas the handler with a null identifier is invoked, if it exists.

Note that the PragmaNamespace class can be used to subdivide pragmas, e.g. we treat "\#pragma STDC" and "\#pragma GCC" as namespaces that contain other pragmas.

getIfNamespace - If this is a namespace, return it.

This is equivalent to using a dynamic_cast, but doesn't require RTTI.

Reimplemented in clang::PragmaNamespace.
