;; The special asm out single letter directives following a '%' are:
;; 'z' mov%z1 would be movl, movw, or movb depending on the mode of
;;     operands[1].
;; 'L' Print the opcode suffix for a 32-bit integer opcode.
;; 'W' Print the opcode suffix for a 16-bit integer opcode.
;; 'B' Print the opcode suffix for an 8-bit integer opcode.
;; 'Q' Print the opcode suffix for a 64-bit float opcode.
;; 'S' Print the opcode suffix for a 32-bit float opcode.
;; 'T' Print the opcode suffix for an 80-bit extended real XFmode float opcode.
;; 'J' Print the appropriate jump operand.
;;
;; 'b' Print the QImode name of the register for the indicated operand.
;;     %b0 would print %al if operands[0] is reg 0.
;; 'w' Likewise, print the HImode name of the register.
;; 'k' Likewise, print the SImode name of the register.
;; 'h' Print the QImode name for a "high" register, either ah, bh, ch or dh.
;; 'y' Print "st(0)" instead of "st" as a register.

;; Arithmetic shift instructions

;; DImode shifts are implemented using the i386 "shift double" opcode,
;; which is written as "sh[lr]d[lw] imm,reg,reg/mem".  If the shift count
;; is variable, then the count is in %cl and the "imm" operand is dropped
;; from the assembler input.
;;
;; This instruction shifts the target reg/mem as usual, but instead of
;; shifting in zeros, bits are shifted in from reg operand.  If the insn
;; is a left shift double, bits are taken from the high order bits of
;; reg, else if the insn is a shift right double, bits are taken from the
;; low order bits of reg.  So if %eax is "1234" and %edx is "5678",
;; "shldl $8,%edx,%eax" leaves %edx unchanged and sets %eax to "2345".
;;
;; Since sh[lr]d does not change the `reg' operand, that is done
;; separately, making all shifts emit pairs of shift double and normal
;; shift.  Since sh[lr]d does not shift more than 31 bits, and we wish to
;; support a 63 bit shift, each shift where the count is in a reg expands
;; to a pair of shifts, a branch, a shift by 32 and a label.
;;
;; If the shift count is a constant, we need never emit more than one
;; shift pair, instead using moves and sign extension for counts greater
;; than 31.

;; SSE logical operations.

;; SSE defines logical operations on floating point values.  This brings
;; interesting challenge to RTL representation where logicals are only valid
;; on integral types.  We deal with this by representing the floating point
;; logical as logical on arguments casted to TImode as this is what hardware
;; really does.  Unfortunately hardware requires the type information to be
;; present and thus we must avoid subregs from being simplified and eliminated
;; in later compilation phases.
;;
;; We have following variants from each instruction:
;; sse_andsf3 - the operation taking V4SF vector operands
;;              and doing TImode cast on them
;; *sse_andsf3_memory - the operation taking one memory operand casted to
;;                      TImode, since backend insist on eliminating casts
;;                      on memory operands
;; sse_andti3_sf_1 - the operation taking SF scalar operands.
;;                   We can not accept memory operand here as instruction reads
;;                   whole scalar.  This is generated only post reload by GCC
;;                   scalar float operations that expands to logicals (fabs)
;; sse_andti3_sf_2 - the operation taking SF scalar input and TImode
;;                   memory operand.  Eventually combine can be able
;;                   to synthesize these using splitter.
;; sse2_anddf3, *sse2_anddf3_memory
;;              
;; 
;; These are not called andti3 etc. because we really really don't want
;; the compiler to widen DImode ands to TImode ands and then try to move
;; into DImode subregs of SSE registers, and them together, and move out
;; of DImode subregs again!
