;; See file "rtl.def" for documentation on define_insn, match_*, et. al.
;;
;; Macro #define NOTICE_UPDATE_CC in file i386.h handles condition code
;; updates for most instructions.
;;
;; Macro REG_CLASS_FROM_LETTER in file i386.h defines the register
;; constraint letters.
;;
;; 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.
;;
;; UNSPEC usage:
;; 0  This is a `scas' operation.  The mode of the UNSPEC is always SImode.
;;    operand 0 is the memory address to scan.
;;    operand 1 is a register containing the value to scan for.  The mode
;;       of the scas opcode will be the same as the mode of this operand.
;;    operand 2 is the known alignment of operand 0.
;; 1  This is a `sin' operation.  The mode of the UNSPEC is MODE_FLOAT.
;;    operand 0 is the argument for `sin'.
;; 2  This is a `cos' operation.  The mode of the UNSPEC is MODE_FLOAT.
;;    operand 0 is the argument for `cos'.
;; 3  This is part of a `stack probe' operation.  The mode of the UNSPEC is 
;;    always SImode.  operand 0 is the size of the stack allocation.
;; 4  This is the source of a fake SET of the frame pointer which is used to
;;    prevent insns referencing it being scheduled across the initial
;;    decrement of the stack pointer.
;; 5  This is a `bsf' operation.
;; 6  This is the @GOT offset of a PIC address.
;; 7  This is the @GOTOFF offset of a PIC address.
;; 8  This is a reference to a symbol's @PLT address.
;; 9  This is an `fnstsw' operation.
;; 10 This is a `sahf' operation.
;; 11 This is a `fstcw' operation
;; 12 This is behaviour of add when setting carry flag.
;; 13 This is a `eh_return' placeholder.

;; For SSE/MMX support:
;; 30 This is `fix', guaranteed to be truncating.
;; 31 This is a `emms' operation.
;; 32 This is a `maskmov' operation.
;; 33 This is a `movmsk' operation.
;; 34 This is a `non-temporal' move.
;; 35 This is a `prefetch' operation.
;; 36 This is used to distinguish COMISS from UCOMISS.
;; 37 This is a `ldmxcsr' operation.
;; 38 This is a forced `movaps' instruction (rather than whatever movti does)
;; 39 This is a forced `movups' instruction (rather than whatever movti does)
;; 40 This is a `stmxcsr' operation.
;; 41 This is a `shuffle' operation.
;; 42 This is a `rcp' operation.
;; 43 This is a `rsqsrt' operation.
;; 44 This is a `sfence' operation.
;; 45 This is a noop to prevent excessive combiner cleverness.

;; 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.

;; Implement switch statements when generating PIC code.  Switches are
;; implemented by `tablejump' when not using -fpic.
;;
;; Emit code here to do the range checking and make the index zero based.
;;
;; Each entry in the "addr_diff_vec" looks like this as the result of the
;; two rules below:
;; 
;;      .long _GLOBAL_OFFSET_TABLE_+[.-.L2]
;; 
;; 1. An expression involving an external reference may only use the
;;    addition operator, and only with an assembly-time constant.
;;    The example above satisfies this because ".-.L2" is a constant.
;; 
;; 2. The symbol _GLOBAL_OFFSET_TABLE_ is magic, and at link time is
;;    given the value of "GOT - .", where GOT is the actual address of
;;    the Global Offset Table.  Therefore, the .long above actually
;;    stores the value "( GOT - . ) + [ . - .L2 ]", or "GOT - .L2".  The
;;    expression "GOT - .L2" by itself would generate an error from as(1).
;; 
;; The pattern below emits code that looks like this:
;; 
;;      movl %ebx,reg
;;      subl TABLE@GOTOFF(%ebx,index,4),reg
;;      jmp reg
;; 
;; The addr_diff_vec contents may be directly referenced with @GOTOFF, since
;; the addr_diff_vec is known to be part of this module.
;; 
;; The subl above calculates "GOT - (( GOT - . ) + [ . - .L2 ])", which
;; evaluates to just ".L2".

;; The ESP adjustments can be done by the push and pop instructions.  Resulting
;; code is shorter, since push is only 1 byte, while add imm, %esp 3 bytes.  On
;; many CPUs it is also faster, since special hardware to avoid esp
;; dependancies is present.

;; While some of these converisons may be done using splitters, we use peepholes
;; in order to allow combine_stack_adjustments pass to see nonobfuscated RTL.

;; Convert prologue esp substractions to push.
;; We need register to push.  In order to keep verify_flow_info happy we have
;; two choices
;; - use scratch and clobber it in order to avoid dependencies
;; - use already live register
;; We can't use the second way right now, since there is no reliable way how to
;; verify that given register is live.  First choice will also most likely in
;; fewer dependencies.  On the place of esp adjustments it is very likely that
;; call clobbered registers are dead.  We may want to use base pointer as an
;; alternative when no register is available later.

;;; 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).
