Compiler macro called for functions declared NOTINLINE

Description

According to 3.2.2.1.3, compiler macros must not be applied if the function is declared notinline. ABCL seems to call them anyways.

To reproduce, compile the following:

(in-package #:cl-user)

(eval-when (:compile-toplevel :load-toplevel :execute)
  (declaim (inline explain))
  (define-compiler-macro explain (&whole form &rest args)
    (declare (ignore args))
    (warn "Compile macro called!")
    form)
  (defgeneric explain (operation component))
  (defmethod explain ((o string) c)
    (declare (notinline explain))
    (explain (find-class (read-from-string o)) c))
  (defmethod explain ((o class) c)
    (format t "~S ~S~%" o c)))

I expect no warning. However, one is signaled.

This is a reduction of something I noticed when prepping for the ASDF 3.4 series. It causes self upgrade to fail on ABCL.

I tried writing a version with normal functions, but couldn't reproduce. So I don't know if I was just doing something wrong or if this only happens with generic functions.
