* libguile/vm-engine.c (BR_U64_SCM_COMPARISON): New helper. (br-if-u64-<=-scm, br-if-u64-<-scm, br-if-u64-=-scm) (br-if-u64->-scm, br-if-u64->=-scm): New instructions, to compare an untagged u64 with a tagged SCM. Avoids many u64->scm operations. * module/language/cps/compile-bytecode.scm (compile-function): * module/language/cps/effects-analysis.scm: * module/language/cps/type-fold.scm: * module/system/vm/assembler.scm: * module/system/vm/disassembler.scm (code-annotation, compute-labels): * module/language/cps/primitives.scm (*branching-primcall-arities*): Add support for new opcodes. * module/language/cps/specialize-numbers.scm (specialize-u64-scm-comparison): New helper. * module/language/cps/specialize-numbers.scm (specialize-operations): Specialize u64 comparisons. * module/language/cps/types.scm (true-comparison-restrictions): New helper. (define-comparison-inferrer): Use the new helper. Add support for u64-<-scm et al.
