;; Macro REG_CLASS_FROM_LETTER in file i386.h defines the register

;;
;; 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.

;;; ix86 doesn't have conditional trap instructions, but we fake them
;;; for the sake of bounds checking.  By emitting bounds checks as
;;; conditional traps rather than as conditional jumps around
;;; unconditional traps we avoid introducing spurious basic-block
;;; boundaries and facilitate elimination of redundant checks.  In
;;; honor of the too-inflexible-for-BPs `bound' instruction, we use
;;; interrupt 5.
;;; 
;;; FIXME: Static branch prediction rules for ix86 are such that
;;; forward conditional branches predict as untaken.  As implemented
;;; below, pseudo conditional traps violate that rule.  We should use
;;; .pushsection/.popsection to place all of the `int 5's in a special
;;; section loaded at the end of the text segment and branch forward
;;; there on bounds-failure, and then jump back immediately (in case
;;; the system chooses to ignore bounds violations, or to report
;;; violations and continue execution).
