* libguile/vm-engine.c (bv-s8-ref, bv-s16-ref, bv-s32-ref, bv-s64-ref): Unbox index and return unboxed S32 value. (bv-s8-set!, bv-s16-set!, bv-s32-set!, bv-s64-set!): Unbox index and take unboxed S32 value. (bv-u8-ref, bv-u16-ref, bv-u32-ref, bv-u64-ref) (bv-s8-set!, bv-s16-set!, bv-s32-set!, bv-s64-set!): Likewise, but with unsigned values. (bv-f32-ref, bv-f32-set!, bv-f64-ref, bv-f64-set!): Use memcpy to access the value so we don't have to think about alignment. GCC will inline this to a single instruction on architectures that support unaligned access. * libguile/vm.c (vm_error_out_of_range_uint64) (vm_error_out_of_range_int64): New helpers. * module/language/cps/slot-allocation.scm (compute-var-representations): All bytevector ref operations produce untagged values. * module/language/cps/types.scm (define-bytevector-accessors): Update for bytevector untagged indices and values. * module/language/cps/utils.scm (compute-constant-values): Fix s64 case. * module/language/tree-il/compile-cps.scm (convert): Box results of all bytevector accesses, and unbox incoming indices and values. |
