#ifndef __ClangBinding_h__
#define __ClangBinding_h__
// This module is needed to hook into the internal behavior of the Clang C++
// parser. Calls to a number of Sema::ActOn... functions are wrapped by means
// of the linker option --wrap=<symbol>. This method has a number restrictions:
// - only works with gnu ld
// - it does not work on MacOS X
// - it only works if calls cannot be resolved by the compiler (an undefined
// symbol references is needed by the linker)
// All that wouldn't be need if the ActOn...-functions of clang::Sema were
// virtual. We hope that this will be changed in the future.
// The implementation hooks into calls from clang::Parser to clang::Sema::ActOn*,
// cast the Sema-object reference to a ClangIntroSema-reference and calls the
// respective ActOn...-function. For ClangIntroSema this looks like the execution
// of a normal virtual function.
// In order to call the original ActOn-function, ClangIntroSema functions call
// Real..., which is provided by this module for all wrapped functions. Calling
// the respective base class method is not possible here, because due to the
// wrapping we would end up with an infinite loop.
