* libguile/vm-engine.c (add/immediate, sub/immediate) (uadd/immediate, usub/immediate, umul/immediate): New instructions. * module/language/cps/compile-bytecode.scm (compile-function): * module/language/cps/slot-allocation.scm (compute-needs-slot): * module/language/cps/types.scm: * module/system/vm/assembler.scm (system): * module/language/cps/effects-analysis.scm: Support for new instructions. * module/language/cps/optimize.scm (optimize-first-order-cps): Move primcall specialization to the last step -- the only benefit of doing it earlier was easier reasoning about side effects, and we're already doing that in a more general way with (language cps types). * module/language/cps/specialize-primcalls.scm (specialize-primcalls): Specialize add and sub to add/immediate and sub/immediate, and specialize u64 addition as well. U64 specialization doesn't work now though because computing constant values doesn't work for U64s; oh well. |
