;;; FRIO branches have been optimized for code density
;;; this comes at a slight cost of complexity when
;;; a compiler needs to generate branches in the general
;;; case.  In order to generate the correct branching
;;; mechanisms the compiler needs keep track of instruction
;;; lengths.  The follow table describes how to count instructions
;;; for the FRIO architecture.
;;;
;;; unconditional br are 12-bit imm pcrelative branches *2
;;; conditional   br are 10-bit imm pcrelative branches *2
;;; brcc 10-bit:
;;;   1024 10-bit imm *2 is 2048 (-1024..1022)
;;; br 12-bit  :
;;;   4096 12-bit imm *2 is 8192 (-4096..4094)
;;; NOTE : For brcc we generate instructions such as
;;;   if cc jmp; jump.[sl] offset
;;;   offset of jump.[sl] is from the jump instruction but
;;;     gcc calculates length from the if cc jmp instruction
;;;     furthermore gcc takes the end address of the branch instruction
;;;     as (pc) for a forward branch
;;;     hence our range is (-4094, 4092) instead of (-4096, 4094) for a br
;;;
;;; The way the (pc) rtx works in these calculations is somewhat odd;
;;; for backward branches it's the address of the current instruction,
;;; for forward branches it's the previously known address of the following
;;; instruction - we have to take this into account by reducing the range
;;; for a forward branch.

;; The Blackfin allows a lot of different options, and we need many patterns to

;; There are a few simple patterns using MULT rtx codes, but most of them use
;; an unspec with a const_int operand that determines which flag to use in the
;; instruction.
;; There are variants for single and parallel multiplications.
;; There are variants which just use 16-bit lowparts as inputs, and variants
;; which allow the user to choose just which halves to use as input values.
;; There are variants which set D registers, variants which set accumulators,
;; variants which set both, some of them optionally using the accumulators as
;; inputs for multiply-accumulate operations.
