(define-isa (name xstormy16) (comment "Xstormy16 instruction set") (default-insn-word-bitsize 32) (default-insn-bitsize 32) ; FIXME base-insn-bitsize should be 16 too, but at present CGEN has ; no support for instruction sets with opcode bits past ; base-insn-bitsize, so we must set it to at least 20. (base-insn-bitsize 32) ) Can anyone remember what the details are? i.e. what didn't work? assembler? disassembler? simulator?
