Message-ID: <bc64b4640910260345q1c91fed2r739530081dbb1a6c@mail.gmail.com> (raw)

Hello,

I have a question regarding generating sim code from cgen description.

I have an instruction operand instantiated from field with type h-addr.
If in the semantics part of the instruction I try to access the operandr
as an address: '(mem QI ddaddr)', I get an error from cgen:

simplify.inc:131:3: op:new-mode: invalid mode for operand `ddaddr': USI

This is the definition of ddaddr:

(dif f-dd-1 "1-byte direct address at 1 position" (ABS-ADDR) 8 8 0 8 UINT #f #f)
(dno ddaddr "direct address" () h-addr f-dd-1)

-- 
With best wishes
Dmitry
