      The big committ: · 8535fe87
      Matthias Braun authored
      - 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.

      Initial commit of morgans spilling algorithm (spill unused values that live through · f436f729
      Matthias Braun authored
      blocks or loops). Other small changes:
      
      * Added some verify functions that check for register pressure or valid schedules (replaces the broken check_pressure in bechordal_main.c)
      * Some style/readability improvements to the belady spill code
      * Some style/readability improvements to beuses.*
      * Fixed registerpressure stat dumper
      * Some improvements to bespill.c: When spilling already reloaded values, don't add a 2nd spill.
