;; :: Constraints
;; ::
;; ::::::::::::::::::::

;; Standard Constraints
;;
;; `m' A memory operand is allowed, with any kind of address that the
;;     machine supports in general.
;;
;; `o' A memory operand is allowed, but only if the address is
;;     "offsettable".  This means that adding a small integer (actually, the
;;     width in bytes of the operand, as determined by its machine mode) may be
;;     added to the address and the result is also a valid memory address.
;;
;; `V' A memory operand that is not offsettable.  In other words,
;;     anything that would fit the `m' constraint but not the `o' constraint.
;;
;; `<' A memory operand with autodecrement addressing (either
;;     predecrement or postdecrement) is allowed.
;;
;; `>' A memory operand with autoincrement addressing (either
;;     preincrement or postincrement) is allowed.
;;
;; `r' A register operand is allowed provided that it is in a general
;;     register.
;;
;; `d', `a', `f', ...
;;     Other letters can be defined in machine-dependent fashion to stand for
;;     particular classes of registers.  `d', `a' and `f' are defined on the
;;     68000/68020 to stand for data, address and floating point registers.
;;
;; `i' An immediate integer operand (one with constant value) is allowed.
;;     This includes symbolic constants whose values will be known only at
;;     assembly time.
;;
;; `n' An immediate integer operand with a known numeric value is allowed.
;;     Many systems cannot support assembly-time constants for operands less
;;     than a word wide.  Constraints for these operands should use `n' rather
;;     than `i'.
;;
;; 'I' First machine-dependent integer constant.
;; 'J' Second machine-dependent integer constant.
;; 'K' Third machine-dependent integer constant.
;; 'L' Fourth machine-dependent integer constant.
;; 'M' Fifth machine-dependent integer constant.
;; 'N' Sixth machine-dependent integer constant.
;; 'O' Seventh machine-dependent integer constant.
;; 'P' Eighth machine-dependent integer constant.
;;
;;     Other letters in the range `I' through `P' may be defined in a
;;     machine-dependent fashion to permit immediate integer operands with
;;     explicit integer values in specified ranges.  For example, on the 68000,
;;     `I' is defined to stand for the range of values 1 to 8.  This is the
;;     range permitted as a shift count in the shift instructions.
;;
;; `E' An immediate floating operand (expression code `const_double') is
;;     allowed, but only if the target floating point format is the same as
;;     that of the host machine (on which the compiler is running).
;;
;; `F' An immediate floating operand (expression code `const_double') is
;;     allowed.
;;
;; 'G' First machine-dependent const_double.
;; 'H' Second machine-dependent const_double.
;;
;; `s' An immediate integer operand whose value is not an explicit
;;     integer is allowed.
;;
;;     This might appear strange; if an insn allows a constant operand with a
;;     value not known at compile time, it certainly must allow any known
;;     value.  So why use `s' instead of `i'?  Sometimes it allows better code
;;     to be generated.
;;
;;     For example, on the 68000 in a fullword instruction it is possible to
;;     use an immediate operand; but if the immediate value is between -128 and
;;     127, better code results from loading the value into a register and
;;     using the register.  This is because the load into the register can be
;;     done with a `moveq' instruction.  We arrange for this to happen by
;;     defining the letter `K' to mean "any integer outside the range -128 to
;;     127", and then specifying `Ks' in the operand constraints.
;;
;; `g' Any register, memory or immediate integer operand is allowed,
;;     except for registers that are not general registers.
;;
;; `X' Any operand whatsoever is allowed, even if it does not satisfy
;;     `general_operand'.  This is normally used in the constraint of a
;;     `match_scratch' when certain alternatives will not actually require a
;;     scratch register.
;;
;; `0' Match operand 0.
;; `1' Match operand 1.
;; `2' Match operand 2.
;; `3' Match operand 3.
;; `4' Match operand 4.
;; `5' Match operand 5.
;; `6' Match operand 6.
;; `7' Match operand 7.
;; `8' Match operand 8.
;; `9' Match operand 9.
;;
;;     An operand that matches the specified operand number is allowed.  If a
;;     digit is used together with letters within the same alternative, the
;;     digit should come last.
;;
;;     This is called a "matching constraint" and what it really means is that
;;     the assembler has only a single operand that fills two roles considered
;;     separate in the RTL insn.  For example, an add insn has two input
;;     operands and one output operand in the RTL, but on most CISC machines an
;;     add instruction really has only two operands, one of them an
;;     input-output operand:
;;
;;          addl #35,r12
;;
;;     Matching constraints are used in these circumstances.  More precisely,
;;     the two operands that match must include one input-only operand and one
;;     output-only operand.  Moreover, the digit must be a smaller number than
;;     the number of the operand that uses it in the constraint.
;;
;;     For operands to match in a particular case usually means that they are
;;     identical-looking RTL expressions.  But in a few special cases specific
;;     kinds of dissimilarity are allowed.  For example, `*x' as an input
;;     operand will match `*x++' as an output operand.  For proper results in
;;     such cases, the output template should always use the output-operand's
;;     number when printing the operand.
;;
;; `p' An operand that is a valid memory address is allowed.  This is for
;;     "load address" and "push address" instructions.
;;
;;     `p' in the constraint must be accompanied by `address_operand' as the
;;     predicate in the `match_operand'.  This predicate interprets the mode
;;     specified in the `match_operand' as the mode of the memory reference for
;;     which the address would be valid.
;;
;; `Q` First non constant, non register machine-dependent insns
;; `R` Second non constant, non register machine-dependent insns
;; `S` Third non constant, non register machine-dependent insns
;; `T` Fourth non constant, non register machine-dependent insns
;; `U` Fifth non constant, non register machine-dependent insns
;;
;;     Letters in the range `Q' through `U' may be defined in a
;;     machine-dependent fashion to stand for arbitrary operand types.  The
;;     machine description macro `EXTRA_CONSTRAINT' is passed the operand as
;;     its first argument and the constraint letter as its second operand.
;;
;;     A typical use for this would be to distinguish certain types of memory
;;     references that affect other insn operands.
;;
;;     Do not define these constraint letters to accept register references
;;     (`reg'); the reload pass does not expect this and would not handle it
;;     properly.

;; Multiple Alternative Constraints
;; `?' Disparage slightly the alternative that the `?' appears in, as a
;;     choice when no alternative applies exactly.  The compiler regards this
;;     alternative as one unit more costly for each `?' that appears in it.
;;
;; `!' Disparage severely the alternative that the `!' appears in.  This
;;     alternative can still be used if it fits without reloading, but if
;;     reloading is needed, some other alternative will be used.

;; Constraint modifiers
;; `=' Means that this operand is write-only for this instruction: the
;;     previous value is discarded and replaced by output data.
;;
;; `+' Means that this operand is both read and written by the
;;     instruction.
;;
;;     When the compiler fixes up the operands to satisfy the constraints, it
;;     needs to know which operands are inputs to the instruction and which are
;;     outputs from it.  `=' identifies an output; `+' identifies an operand
;;     that is both input and output; all other operands are assumed to be
;;     input only.
;;
;; `&' Means (in a particular alternative) that this operand is written
;;     before the instruction is finished using the input operands.  Therefore,
;;     this operand may not lie in a register that is used as an input operand
;;     or as part of any memory address.
;;
;;     `&' applies only to the alternative in which it is written.  In
;;     constraints with multiple alternatives, sometimes one alternative
;;     requires `&' while others do not.
;;
;;     `&' does not obviate the need to write `='.
;;
;; `%' Declares the instruction to be commutative for this operand and the
;;     following operand.  This means that the compiler may interchange the two
;;     operands if that is the cheapest way to make all operands fit the
;;     constraints.  This is often used in patterns for addition instructions
;;     that really have only two operands: the result must go in one of the
;;     arguments.
;;
;; `#' Says that all following characters, up to the next comma, are to be
;;     ignored as a constraint.  They are significant only for choosing
;;     register preferences.
;;
;; `*' Says that the following character should be ignored when choosing
;;     register preferences.  `*' has no effect on the meaning of the
;;     constraint as a constraint, and no effect on reloading.

;; :: Attributes
;; ::
;; ::::::::::::::::::::

;; The `define_attr' expression is used to define each attribute required by
;; the target machine.  It looks like:
;;
;; (define_attr NAME LIST-OF-VALUES DEFAULT)

;; NAME is a string specifying the name of the attribute being defined.

;; LIST-OF-VALUES is either a string that specifies a comma-separated list of
;; values that can be assigned to the attribute, or a null string to indicate
;; that the attribute takes numeric values.

;; DEFAULT is an attribute expression that gives the value of this attribute
;; for insns that match patterns whose definition does not include an explicit
;; value for this attribute.

;; For each defined attribute, a number of definitions are written to the
;; `insn-attr.h' file.  For cases where an explicit set of values is specified
;; for an attribute, the following are defined:

;; * A `#define' is written for the symbol `HAVE_ATTR_NAME'.
;;
;; * An enumeral class is defined for `attr_NAME' with elements of the
;;   form `UPPER-NAME_UPPER-VALUE' where the attribute name and value are first
;;   converted to upper case.
;;
;; * A function `get_attr_NAME' is defined that is passed an insn and
;;   returns the attribute value for that insn.

;; For example, if the following is present in the `md' file:
;;
;; (define_attr "type" "branch,fp,load,store,arith" ...)
;;
;; the following lines will be written to the file `insn-attr.h'.
;;
;; #define HAVE_ATTR_type
;; enum attr_type {TYPE_BRANCH, TYPE_FP, TYPE_LOAD, TYPE_STORE, TYPE_ARITH};
;; extern enum attr_type get_attr_type ();

;; If the attribute takes numeric values, no `enum' type will be defined and
;; the function to obtain the attribute's value will return `int'.

;; Note, we lie a little bit here to make it simpler to optimize.  We pretend there
;; is a separate long functional unit for long instructions that uses both the IU & MU.

;; ::::::::::::::::::::
;; ::
;; :: Function Units
;; ::
;; ::::::::::::::::::::

;; On most RISC machines, there are instructions whose results are not
;; available for a specific number of cycles.  Common cases are instructions
;; that load data from memory.  On many machines, a pipeline stall will result
;; if the data is referenced too soon after the load instruction.

;; In addition, many newer microprocessors have multiple function units,
;; usually one for integer and one for floating point, and often will incur
;; pipeline stalls when a result that is needed is not yet ready.

;; The descriptions in this section allow the specification of how much time
;; must elapse between the execution of an instruction and the time when its
;; result is used.  It also allows specification of when the execution of an
;; instruction will delay execution of similar instructions due to function
;; unit conflicts.

;; For the purposes of the specifications in this section, a machine is divided
;; into "function units", each of which execute a specific class of
;; instructions in first-in-first-out order.  Function units that accept one
;; instruction each cycle and allow a result to be used in the succeeding
;; instruction (usually via forwarding) need not be specified.  Classic RISC
;; microprocessors will normally have a single function unit, which we can call
;; `memory'.  The newer "superscalar" processors will often have function units
;; for floating point operations, usually at least a floating point adder and
;; multiplier.

;; Each usage of a function units by a class of insns is specified with a
;; `define_function_unit' expression, which looks like this:

;; (define_function_unit NAME MULTIPLICITY SIMULTANEITY TEST READY-DELAY
;;   ISSUE-DELAY [CONFLICT-LIST])

;; NAME is a string giving the name of the function unit.

;; MULTIPLICITY is an integer specifying the number of identical units in the
;; processor.  If more than one unit is specified, they will be scheduled
;; independently.  Only truly independent units should be counted; a pipelined
;; unit should be specified as a single unit.  (The only common example of a
;; machine that has multiple function units for a single instruction class that
;; are truly independent and not pipelined are the two multiply and two
;; increment units of the CDC 6600.)

;; SIMULTANEITY specifies the maximum number of insns that can be executing in
;; each instance of the function unit simultaneously or zero if the unit is
;; pipelined and has no limit.

;; All `define_function_unit' definitions referring to function unit NAME must
;; have the same name and values for MULTIPLICITY and SIMULTANEITY.

;; TEST is an attribute test that selects the insns we are describing in this
;; definition.  Note that an insn may use more than one function unit and a
;; function unit may be specified in more than one `define_function_unit'.

;; READY-DELAY is an integer that specifies the number of cycles after which
;; the result of the instruction can be used without introducing any stalls.

;; ISSUE-DELAY is an integer that specifies the number of cycles after the
;; instruction matching the TEST expression begins using this unit until a
;; subsequent instruction can begin.  A cost of N indicates an N-1 cycle delay.
;; A subsequent instruction may also be delayed if an earlier instruction has a
;; longer READY-DELAY value.  This blocking effect is computed using the
;; SIMULTANEITY, READY-DELAY, ISSUE-DELAY, and CONFLICT-LIST terms.  For a
;; normal non-pipelined function unit, SIMULTANEITY is one, the unit is taken
;; to block for the READY-DELAY cycles of the executing insn, and smaller
;; values of ISSUE-DELAY are ignored.

;; CONFLICT-LIST is an optional list giving detailed conflict costs for this
;; unit.  If specified, it is a list of condition test expressions to be
;; applied to insns chosen to execute in NAME following the particular insn
;; matching TEST that is already executing in NAME.  For each insn in the list,
;; ISSUE-DELAY specifies the conflict cost; for insns not in the list, the cost
;; is zero.  If not specified, CONFLICT-LIST defaults to all instructions that
;; use the function unit.

;; Typical uses of this vector are where a floating point function unit can
;; pipeline either single- or double-precision operations, but not both, or
;; where a memory unit can pipeline loads, but not stores, etc.

;; As an example, consider a classic RISC machine where the result of a load
;; instruction is not available for two cycles (a single "delay" instruction is
;; required) and where only one load instruction can be executed
;; simultaneously.  This would be specified as:

;; (define_function_unit "memory" 1 1 (eq_attr "type" "load") 2 0)

;; For the case of a floating point function unit that can pipeline
;; either single or double precision, but not both, the following could be
;; specified:
;;
;; (define_function_unit "fp" 1 0
;;   (eq_attr "type" "sp_fp") 4 4
;;   [(eq_attr "type" "dp_fp")])
;;
;; (define_function_unit "fp" 1 0
;;   (eq_attr "type" "dp_fp") 4 4
;;   [(eq_attr "type" "sp_fp")])

;; Note: The scheduler attempts to avoid function unit conflicts and uses all
;; the specifications in the `define_function_unit' expression.  It has
;; recently come to our attention that these specifications may not allow
;; modeling of some of the newer "superscalar" processors that have insns using
;; multiple pipelined units.  These insns will cause a potential conflict for
;; the second unit used during their execution and there is no way of
;; representing that conflict.  We welcome any examples of how function unit
;; conflicts work in such processors and suggestions for their representation.

;; ::::::::::::::::::::
;; ::
;; :: Delay Slots
;; ::
;; ::::::::::::::::::::

;; The insn attribute mechanism can be used to specify the requirements for
;; delay slots, if any, on a target machine.  An instruction is said to require
;; a "delay slot" if some instructions that are physically after the
;; instruction are executed as if they were located before it.  Classic
;; examples are branch and call instructions, which often execute the following
;; instruction before the branch or call is performed.

;; On some machines, conditional branch instructions can optionally "annul"
;; instructions in the delay slot.  This means that the instruction will not be
;; executed for certain branch outcomes.  Both instructions that annul if the
;; branch is true and instructions that annul if the branch is false are
;; supported.

;; Delay slot scheduling differs from instruction scheduling in that
;; determining whether an instruction needs a delay slot is dependent only
;; on the type of instruction being generated, not on data flow between the
;; instructions.  See the next section for a discussion of data-dependent
;; instruction scheduling.

;; The requirement of an insn needing one or more delay slots is indicated via
;; the `define_delay' expression.  It has the following form:
;;
;; (define_delay TEST
;;   [DELAY-1 ANNUL-TRUE-1 ANNUL-FALSE-1
;;    DELAY-2 ANNUL-TRUE-2 ANNUL-FALSE-2
;;    ...])

;; TEST is an attribute test that indicates whether this `define_delay' applies
;; to a particular insn.  If so, the number of required delay slots is
;; determined by the length of the vector specified as the second argument.  An
;; insn placed in delay slot N must satisfy attribute test DELAY-N.
;; ANNUL-TRUE-N is an attribute test that specifies which insns may be annulled
;; if the branch is true.  Similarly, ANNUL-FALSE-N specifies which insns in
;; the delay slot may be annulled if the branch is false.  If annulling is not
;; supported for that delay slot, `(nil)' should be coded.

;; For example, in the common case where branch and call insns require a single
;; delay slot, which may contain any insn other than a branch or call, the
;; following would be placed in the `md' file:

;; (define_delay (eq_attr "type" "branch,call")
;;		 [(eq_attr "type" "!branch,call") (nil) (nil)])

;; Multiple `define_delay' expressions may be specified.  In this case, each
;; such expression specifies different delay slot requirements and there must
;; be no insn for which tests in two `define_delay' expressions are both true.

;; For example, if we have a machine that requires one delay slot for branches
;; but two for calls, no delay slot can contain a branch or call insn, and any
;; valid insn in the delay slot for the branch can be annulled if the branch is
;; true, we might represent this as follows:

;; (define_delay (eq_attr "type" "branch")
;;   [(eq_attr "type" "!branch,call")
;;    (eq_attr "type" "!branch,call")
;;    (nil)])
;;
;; (define_delay (eq_attr "type" "call")
;;   [(eq_attr "type" "!branch,call") (nil) (nil)
;;    (eq_attr "type" "!branch,call") (nil) (nil)])


;; ::::::::::::::::::::
;; ::
;; :: Moves
;; ::
;; ::::::::::::::::::::

;; Wrap moves in define_expand to prevent memory->memory moves from being
;; generated at the RTL level, which generates better code for most machines
;; which can't do mem->mem moves.

;; If operand 0 is a `subreg' with mode M of a register whose own mode is wider
;; than M, the effect of this instruction is to store the specified value in
;; the part of the register that corresponds to mode M.  The effect on the rest
;; of the register is undefined.

;; This class of patterns is special in several ways.  First of all, each of
;; these names *must* be defined, because there is no other way to copy a datum
;; from one place to another.

;; Second, these patterns are not used solely in the RTL generation pass.  Even
;; the reload pass can generate move insns to copy values from stack slots into
;; temporary registers.  When it does so, one of the operands is a hard
;; register and the other is an operand that can need to be reloaded into a
;; register.

;; Therefore, when given such a pair of operands, the pattern must
;; generate RTL which needs no reloading and needs no temporary
;; registers--no registers other than the operands.  For example, if
;; you support the pattern with a `define_expand', then in such a
;; case the `define_expand' mustn't call `force_reg' or any other such
;; function which might generate new pseudo registers.

;; This requirement exists even for subword modes on a RISC machine
;; where fetching those modes from memory normally requires several
;; insns and some temporary registers.  Look in `spur.md' to see how
;; the requirement can be satisfied.

;; During reload a memory reference with an invalid address may be passed as an
;; operand.  Such an address will be replaced with a valid address later in the
;; reload pass.  In this case, nothing may be done with the address except to
;; use it as it stands.  If it is copied, it will not be replaced with a valid
;; address.  No attempt should be made to make such an address into a valid
;; address and no routine (such as `change_address') that will do so may be
;; called.  Note that `general_operand' will fail when applied to such an
;; address.
;;
;; The global variable `reload_in_progress' (which must be explicitly declared
;; if required) can be used to determine whether such special handling is
;; required.
;;
;; The variety of operands that have reloads depends on the rest of
;; the machine description, but typically on a RISC machine these can
;; only be pseudo registers that did not get hard registers, while on
;; other machines explicit memory references will get optional
;; reloads.
;;
;; If a scratch register is required to move an object to or from memory, it
;; can be allocated using `gen_reg_rtx' prior to reload.  But this is
;; impossible during and after reload.  If there are cases needing scratch
;; registers after reload, you must define `SECONDARY_INPUT_RELOAD_CLASS' and
;; perhaps also `SECONDARY_OUTPUT_RELOAD_CLASS' to detect them, and provide
;; patterns `reload_inM' or `reload_outM' to handle them.  *Note Register
;; Classes::.

;; The constraints on a `moveM' must permit moving any hard register to any
;; other hard register provided that `HARD_REGNO_MODE_OK' permits mode M in
;; both registers and `REGISTER_MOVE_COST' applied to their classes returns a
;; value of 2.

;; It is obligatory to support floating point `moveM' instructions
;; into and out of any registers that can hold fixed point values,
;; because unions and structures (which have modes `SImode' or
;; `DImode') can be in those registers and they may have floating
;; point members.

;; There may also be a need to support fixed point `moveM' instructions in and
;; out of floating point registers.  Unfortunately, I have forgotten why this
;; was so, and I don't know whether it is still true.  If `HARD_REGNO_MODE_OK'
;; rejects fixed point values in floating point registers, then the constraints
;; of the fixed point `moveM' instructions must be designed to avoid ever
;; trying to reload into a floating point register.
