CALLQ, INDCALLQ and TAILJMP should have only 1 argument.

Definition in utilities.rkt:

(struct Callq (target)
  #:methods gen:custom-write
  [(define (write-proc ast port mode)
     (match ast
       [(Callq target)
        (let-values ([(line col pos) (port-next-location port)])
          (write-string "callq" port)
          (write-string " " port)
          (write target port)
          (newline-and-indent port col))
        ]))])

Hi Noah,

The utilities.rkt file that you are looking at is out of date. Those structs all take two parameters now. I recommend pulling the new version from the public-student-support-code repository.

Best regards Jeremy

I used utilities.rkt from IU-P423-P523-E313-E513-Fall-2020 before. I apologize for the confusion.

No worries. Thank you for your interest in the book!
