After. See passes.c. > 2) Also, is it possible for me to add my own "demands" (or suggestions) > into the register allocator? It really depends on what you mean. There are command line options like -ffixed-REG. If you edit the CPU.md file you can specify register classes for particular insns. If you want to rewrite the instruction stream you can do your own register allocation by replacing some pseudo-regs with hard regs. Ian
