+;; The letters I, J, K, L, M, N, O, P in a register constraint string
+;; can be used to stand for particular ranges of immediate operands.
+;; The letters Q, R, S, T, U are used to segregate specific types of
+;; operands, usually memory references, for the target machine.
+;;
+;; I is used for 8-bit signed immediates.
+;; J is used for 16-bit signed immediates.
+;; K is used for 16-bit unsigned immediates.
+;; L is used for 16-bit immediates left shifted by 16 (sign ???).
+;; M is used for 24-bit unsigned immediates.
+;; N is used for 8-bit signed immediates for compares
+;;   (values in the range -127 to +128).
+;; O is used for 5-bit unsigned immediates (shift count).
+;; P is used for 16-bit signed immediates for compares
+;;     (values in the range -32767 to +32768).
+;;
+;; Q is for symbolic addresses loadable with ld24.
+;; R is for symbolic addresses when ld24 can't be used.
+;; S is for stores with pre {inc,dec}rement
+;; T is for indirect of a pointer.
+;; U is for loads with post increment.
+;; W is used for an immediate value of 0.
