The big committ:
- Replace limit callback in register requirements with a simple bitset - Fix backends, generators and the rest of the code for the change register requirements structure - Eliminated the custom register_requirement structures in the backend, they are pointless now, use the normal arch_register_req_t - Fix TEMPLATE backend - Extract emitter framework from ia32 and provide generic header/code for it - Port TEMPLATE backend to new emitter - Extract gas specific emit stuff (declarations, sections) from ia32 backend and provide it as generic header/code. Make TEMPLATE backend use that - Remove several FIRM_DBG_REGISTERs from functions which are called very often. Before we had millions of string hashtable lookups because of that. The prefered way is to have 1 static debug module per file and initialize it in the module constructor. No passing around in environment structs and in no case should you dynamically register it in single functions.
