29 ;; 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.",
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
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
