big refactoring of arch_XXX functions
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)
