cl:disassemble on SBCL generally comments out each of its lines of output with a single semi-colon as in:
* (defun foo ())
FOO
* (disassemble #'foo)
; disassembly for FOO
; Size: 28 bytes. Origin: #x10026B0073 ; FOO
; 73: 498B4510 MOV RAX, [R13+16] ; thread.binding-stack-pointer
; 77: 488945F8 MOV [RBP-8], RAX
; 7B: 840425F8FF1020 TEST AL, [#x2010FFF8] ; safepoint
; 82: BA17001120 MOV EDX, #x20110017 ; NIL
; 87: 488BE5 MOV RSP, RBP
; 8A: F8 CLC
; 8B: 5D POP RBP
; 8C: C3 RET
; 8D: CC10 INT3 16 ; Invalid argument count trap
NIL
However, it seems to behave differently for generic functions:
* (defgeneric bar ())
#<STANDARD-GENERIC-FUNCTION COMMON-LISP-USER::BAR (0)>
* (disassemble #'bar)
; disassembly for BAR
; Size: 70 bytes. Origin: #x10000EB857 ; (LAMBDA
