problem with derived operands

[Johan Rydberg <johan dot rydberg at netinsight dot se>]

Hi!

I'm trying to implement (another) CPU description with CGEN.
I have ran into some problems with derived operands.  I have
the following fields;

(dnf  f-const-op1 "const op 1"          () 7 8)

the following operands;

(define-operand
  (name const-base)
  (comment "base constant or something")
  (mode QI)
  (type h-uint)
  (index f-const-op1)
)

(dndo const-8
      QI
      (const-base)
      "${const-base}"
      f-const-op1
      (+ const-base)
      ()
      const-base
      () ; no setter
)

When I'm trying to use the ''const-8'' field within a insn,
I get the following error;

ERROR: Unbound variable: op-ifld

Here's the insn definition;

(dni bipush "bipush"
  ()
  "bipush ${const-8}"
  (+ OC_16 const-8)
  (sequence()
     (set (mem QI (reg h-gr 14)) const-8)
     (set (reg h-gr 14) (sub (reg h-gr 14) (const 4)))
  )
  ()
)

Can anyone tell me what I do wrong ?
