Would that code be comp--spill-lap-function, perhaps?  There are
currently three functions with that name, each for a different type of
argument.

It's apparent that the one that used to work,

    (cl-defmethod comp--spill-lap-function ((form list))                                                                   

, no longer works since function forms were converted to a different
format in March.  It needs modifying to handle the new format.

I don't really see where the problem is: comp--spill-lap-function, all
versions, isolates the Lisp source form, passes it to the byte compiler
and receives the intermediate compiled form in the hash table
byte-to-native-lambdas-h.  This intermediate form is then fed to the
native compilation engine.

Or am I not understanding what you're asking?
