/* Notes:
|
|
* Before you start changing something in this file be aware of the following:
|
|
*
|
|
* - There are several functions called recursively. In a very subtle and
|
|
* obscure way. DLLs can reference each other recursively etc.
|
|
* - If you want to enhance, speed up or clean up something in here, think
|
|
* twice WHY it is implemented in that strange way. There is usually a reason.
|
|
* Though sometimes it might just be lazyness ;)
|
|
* - In PE_MapImage, right before fixup_imports() all external and internal
|
|
* state MUST be correct since this function can be called with the SAME image
|
|
* AGAIN. (Thats recursion for you.) That means MODREF.module and
|
|
* NE_MODULE.module32.
