;; 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
-;; E,e -- likewise, but for compare-and-branch fused insn.
;; F,f -- likewise, but for floating-point.
;; O -- if HAVE_AS_IX86_CMOV_SUN_SYNTAX, expand to "w.", "l." or "q.",
;; otherwise nothing
;; 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
+;; 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).

-;; 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.

+;; 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.
