;; The special asm out single letter directives following a '%' are:
;; L,W,B,Q,S,T -- print the opcode suffix for specified size of operand.
;; C -- print opcode suffix for set/cmov insn.
;; c -- like C, but print reversed condition
;; F,f -- likewise, but for floating-point.
;; O -- if HAVE_AS_IX86_CMOV_SUN_SYNTAX, expand to "w.", "l." or "q.",
;;      otherwise nothing
;; R -- print the prefix for register names.
;; z -- print the opcode suffix for the size of the current operand.
;; Z -- likewise, with special suffixes for x87 instructions.
;; * -- print a star (in certain assembler syntax)
;; A -- print an absolute memory reference.
;; E -- print address with DImode register names if TARGET_64BIT.
;; w -- print the operand as if it's a "word" (HImode) even if it isn't.
;; s -- print a shift double count, followed by the assemblers argument
;;	delimiter.
;; 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.
;; q --  likewise, print the DImode name of the register.
;; x --  likewise, print the V4SFmode name of the register.
;; t --  likewise, print the V8SFmode 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.
;; d -- print duplicated register operand for AVX instruction.
;; D -- print condition for SSE cmp instruction.
;; P -- if PIC, print an @PLT suffix.
;; p -- print raw symbol name.
;; X -- don't print any sort of PIC '@' suffix for a symbol.
;; & -- print some in-use local-dynamic symbol name.
;; H -- print a memory address offset by 8; used for sse high-parts
;; K -- print HLE lock prefix
;; Y -- print condition for XOP pcom* instruction.
;; + -- print a branch hint as 'cs' or 'ds' prefix
;; ; -- print a semicolon (after prefixes due to bug in older gas).
;; ~ -- print "i" if TARGET_AVX2, "f" otherwise.
;; ^ -- print addr32 prefix if TARGET_64BIT and Pmode != word_mode
;; ! -- print NOTRACK prefix for jxx/call/ret instructions if required.

;; 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.
