Subject: derived operands
Date: Mon, 19 Mar 2001 10:48:00 -0000 [thread overview]
Message-ID: <3AB65497.3F8C6737@cygnus.com> (raw)
I recently ran into a problem that I tracked down to a derived-operand I used directly in an
instruction (i.e. did not wrapper it in an anyof-operand). CGEN generated my opcode files fine,
however, when I attempted to assemble the insn that referred to the dndo, I got an assembler parse
error because it did not recognize the opindex of the dndo operand. Adding an anyof-operand with
one choice solved the problem and I have since reworked my code so that I use the anyof-operand
properly to encapsulate two choices.
Is it intentional that a derived-operand cannot be used directly as an operand in an instruction?
If yes, could CGEN at least fail when generating the opcodes files?
