  ; This is 32 because 16 bit insns always appear as pairs.
75
  ; ??? See if this can go away.  It's only used by the disassembler (right?)
76
  ; to decide how long an unknown insn is.  One value isn't sufficient (e.g. if
77
  ; on a 16 bit (and not 32 bit) boundary, will only want to advance pc by 16.)

80
  ; Number of bytes of insn we can initially fetch.
81
  ; The M32R is tricky in that insns are either two 16-bit insns
82
  ; (executed sequentially or in parallel) or one 32-bit insn.
83
  ; So on one hand the base insn size is 16 bits, but on another it's 32.
84
  ; 32 is chosen because:
85
  ; - if the chip were ever bi-endian it is believed that the byte order would
86
  ;   be based on 32 bit quantities
87
  ; - 32 bit insns are always aligned on 32 bit boundaries
88
  ; - the pc will never stop on a 16 bit (and not 32 bit) boundary
89
  ;   [well actually it can, but there are no branches to such places]
