;; The special asm out single letter directives following a '%' are:
30
;; L,W,B,Q,S,T -- print the opcode suffix for specified size of operand.
31
;; C -- print opcode suffix for set/cmov insn.
32
;; c -- like C, but print reversed condition
33
;; F,f -- likewise, but for floating-point.
34
;; O -- if HAVE_AS_IX86_CMOV_SUN_SYNTAX, expand to "w.", "l." or "q.",
35
;;      otherwise nothing
36
;; R -- print the prefix for register names.
37
;; z -- print the opcode suffix for the size of the current operand.
38
;; Z -- likewise, with special suffixes for x87 instructions.
39
;; * -- print a star (in certain assembler syntax)
40
;; A -- print an absolute memory reference.
41
;; w -- print the operand as if it's a "word" (HImode) even if it isn't.
42
;; s -- print a shift double count, followed by the assemblers argument
43
;;      delimiter.
44
;; b -- print the QImode name of the register for the indicated operand.
45
;;      %b0 would print %al if operands[0] is reg 0.
46
;; w --  likewise, print the HImode name of the register.
47
;; k --  likewise, print the SImode name of the register.
48
;; q --  likewise, print the DImode name of the register.
49
;; x --  likewise, print the V4SFmode name of the register.
50
;; t --  likewise, print the V8SFmode name of the register.
51
;; h -- print the QImode name for a "high" register, either ah, bh, ch or dh.
52
;; y -- print "st(0)" instead of "st" as a register.
53
;; d -- print duplicated register operand for AVX instruction.
54
;; D -- print condition for SSE cmp instruction.
55
;; P -- if PIC, print an @PLT suffix.
56
;; p -- print raw symbol name.
57
;; X -- don't print any sort of PIC '@' suffix for a symbol.
58
;; & -- print some in-use local-dynamic symbol name.
59
;; H -- print a memory address offset by 8; used for sse high-parts
60
;; Y -- print condition for XOP pcom* instruction.
61
;; + -- print a branch hint as 'cs' or 'ds' prefix
62
;; ; -- print a semicolon (after prefixes due to bug in older gas).
63
;; @ -- print a segment register of thread base pointer load

;; from the assembler input.
8895

;; This instruction shifts the target reg/mem as usual, but instead of
8897
;; shifting in zeros, bits are shifted in from reg operand.  If the insn

8899
;; reg, else if the insn is a shift right double, bits are taken from the
8900
;; low order bits of reg.  So if %eax is "1234" and %edx is "5678",
8901
;; "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

8906

8907
