      big refactoring of arch_XXX functions · 41dc42af
      Matthias Braun authored
      This tries to get the names in a consistent format. We basically have 2
      views on register allocation/constraints now:
      
      1) Register Requirements and Assigments are per-instruction. Each
         instruction has requirements on its inputs and outputs, register get
         assigned for outputs of an instruction (assignment is an attribute of
         an instruction, not of the Proj-nodes).
         The internal datastructures model this form!
      
         The functions here have the form:
           arch_get_irn_register_req_in(node, input_nr)
           arch_get_irn_register_in(node, input_nr)
           arch_get_irn_register_req_out(node, output_nr)
           arch_set_irn_register_out(node, output_nr, register)
      
      2) Register Requirements and Assignments are on firm-values. This view
         allows to query/assign requirements and registers at the Proj nodes
         instead of the repsective predecessors.
         This is a convenience interface modeled on top of the other!
      
         The functions have the form:
           arch_get_irn_register_req(node)
           arch_get_irn_register(node)
           arch_set_irn_register(node, register)

      Rework linkage types in firm. · 2bc2dd4b
      Matthias Braun authored
      - Merge stickyness, visibility and variability into ir_linkage
      - Add proper support for common symbols, weak symbols and C++ COMDAT stuff
      - Mark OO-features type_visibility, peculiarity and allocation as deprecated
        OO feature will be separated from firm core into higher levels in the long run
      - Rework, simplify and fix bugs in begnuas.c
