Detailed Description

Writes an AST file containing the contents of a translation unit.

The ASTWriter class produces a bitstream containing the serialized representation of a given abstract syntax tree and its supporting data structures. This bitstream can be de-serialized via an instance of the ASTReader class.

Write a precompiled header or a module with the AST produced by the Sema object, or a dependency scanner module with the preprocessor state produced by the Preprocessor object.

Parameters

Subject	The `Sema` object that processed the AST to be written, or in the case of a dependency scanner module the `Preprocessor` that holds the state.
WritingModule	The module that we are writing. If null, we are writing a precompiled header.
isysroot	if non-empty, write a relocatable file whose headers are relative to the given system root. If we're writing a module, its build directory will be used in preference to this if both are available.

Returns: the module signature, which eventually will be a hash of the module but currently is merely a random 32-bit number.
