;; Special formats used for outputting 390 instructions.

;;     %C: print opcode suffix for branch condition.
;;     %D: print opcode suffix for inverse branch condition.
;;     %J: print tls_load/tls_gdcall/tls_ldcall suffix
;;     %G: print the size of the operand in bytes.
;;     %O: print only the displacement of a memory reference.
;;     %R: print only the base register of a memory reference.
;;     %S: print S-type memory reference (base+displacement).
;;     %N: print the second word of a DImode operand.
;;     %M: print the second word of a TImode operand.
;;     %Y: print shift count operand.
;;
;;     %b: print integer X as if it's an unsigned byte.
;;     %c: print integer X as if it's an signed byte.
;;     %x: print integer X as if it's an unsigned halfword.
;;     %h: print integer X as if it's a signed halfword.
;;     %i: print the first nonzero HImode part of X.
;;     %j: print the first HImode part unequal to -1 of X.
;;     %k: print the first nonzero SImode part of X.
;;     %m: print the first SImode part unequal to -1 of X.
;;     %o: print integer X as if it's an unsigned 32bit word.
;;
;; We have a special constraint for pattern matching.
