; Attributes:
; PCREL-ADDR: pc relative value (for reloc and disassembly purposes)
; ABS-ADDR: absolute address (for reloc and disassembly purposes?)
; RESERVED: bits are not used to decode insn, must be all 0
; RELOC: there is a relocation associated with this field (experiment)
;
; f-msys: Identify a a morphosys insns.  1 if msys, 0 if not.
; f-opc: 6 bit opcode for non-morphosys instructions.
; f-msopc: 6 bit opcode for morphosys instructions.
; f-imm: flag to indicate use of an immediate operand.  1 if yes, 0 if no.
; f-sr1: source resgister 1. (also used for MSYS insns)
; f-sr2: source register 2. (also used for MSYS insns)
; f-dr: destination register when located in bits 19:16.
; f-drrr: destination register when located in bits 15:12. (also for MSYS insns)
; f-imm16: 16 bit immediate value when not an offset.
; f-imm16a: 16 bit immediate value when it's a pc-rel offset.
; f-uu4a: unused 4 bit field.
