+ ;; VOPs. Such platforms should implement real-complex, complex-real and
+ ;; complex-complex addition and subtractions (for complex-single-float
+ ;; and complex-double-float). They should also also implement complex-real
+ ;; and real-complex multiplication, complex-real division, and
+ ;; sb!vm::swap-complex, which swaps the real and imaginary parts.
+ ;; Finally, they should implement conjugate and complex-real, real-complex
+ ;; and complex-complex CL:= (complex-complex EQL would usually be a good
+ ;; idea).
