;; :: 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 (6 bit signed ints).
;; 'J' Second machine-dependent integer constant (10 bit signed ints).
;; 'K' Third machine-dependent integer constant (-2048).
;; 'L' Fourth machine-dependent integer constant (16 bit signed ints).
;; 'M' Fifth machine-dependent integer constant (16 bit unsigned ints).
;; 'N' Sixth machine-dependent integer constant (-2047..-1).
;; 'O' Seventh machine-dependent integer constant (zero).
;; 'P' Eighth machine-dependent integer constant (1..2047).
;;
;;     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'.

(define_attr "length" "" (const_int 4))

;; Processor type -- this attribute must exactly match the processor_type
;; enumeration in frv-protos.h.

(define_attr "cpu" "generic,fr500,fr400,fr300,simple,tomcat"
  (const (symbol_ref "frv_cpu_type")))

;; Attribute is "yes" for branches and jumps that span too great a distance
;; to be implemented in the most natural way.  Such instructions will use
;; a call instruction in some way.

(define_attr "far_jump" "yes,no" (const_string "no"))

;; Instruction type

;; The table below summarizes the types of media instruction and their
;; scheduling classification.  Headings are:

;; Type:        the name of the define_attr type
;; Conditions:  "yes" if conditional variants are available
;; FR500:       Fujitsu's categorization for the FR500
;; FR400:       Fujitsu's categorization for the FR400 (but see below).

;; On the FR400, media instructions are divided into 2 broad categories.
;; Category 1 instructions can execute in either the M0 or M1 unit and can
;; execute in parallel with other category 1 instructions.  Category 2
;; instructions must use the M0 unit, and therefore cannot run in parallel
;; with other media instructions.

;; The FR400 documentation also divides media instructions into one of seven
;; categories (m1 to m7).  m1 to m4 contain both Category 1 and Category 2
;; instructions, so we use a combination of the categories here.

/* This is description of pipeline hazards based on DFA.  The
   following constructions can be used for this:

   o define_cpu_unit string [string]) describes a cpu functional unit
     (separated by comma).

     1st operand: Names of cpu function units.
     2nd operand: Name of automaton (see comments for
     DEFINE_AUTOMATON).

     All define_reservations and define_cpu_units should have unique
     names which can not be "nothing".

   o (exclusion_set string string) means that each CPU function unit
     in the first string can not be reserved simultaneously with each
     unit whose name is in the second string and vise versa.  CPU
     units in the string are separated by commas. For example, it is
     useful for description CPU with fully pipelined floating point
     functional unit which can execute simultaneously only single
     floating point insns or only double floating point insns.

   o (presence_set string string) means that each CPU function unit in
     the first string can not be reserved unless at least one of units
     whose names are in the second string is reserved.  This is an
     asymmetric relation.  CPU units in the string are separated by
     commas.  For example, it is useful for description that slot1 is
     reserved after slot0 reservation for a VLIW processor.

   o (absence_set string string) means that each CPU function unit in
     the first string can not be reserved only if each unit whose name
     is in the second string is not reserved.  This is an asymmetric
     relation (actually exclusion set is analogous to this one but it
     is symmetric).  CPU units in the string are separated by commas.
     For example, it is useful for description that slot0 can not be
     reserved after slot1 or slot2 reservation for a VLIW processor.

   o (define_bypass number out_insn_names in_insn_names) names bypass with
     given latency (the first number) from insns given by the first
     string (see define_insn_reservation) into insns given by the
     second string.  Insn names in the strings are separated by
     commas.

   o (define_automaton string) describes names of an automaton
     generated and used for pipeline hazards recognition.  The names
     are separated by comma.  Actually it is possibly to generate the
     single automaton but unfortunately it can be very large.  If we
     use more one automata, the summary size of the automata usually
     is less than the single one.  The automaton name is used in
     define_cpu_unit.  All automata should have unique names.

   o (define_reservation string string) names reservation (the first
     string) of cpu functional units (the 2nd string).  Sometimes unit
     reservations for different insns contain common parts.  In such
     case, you describe common part and use one its name (the 1st
     parameter) in regular expression in define_insn_reservation.  All
     define_reservations, define results and define_cpu_units should
     have unique names which can not be "nothing".

   o (define_insn_reservation name default_latency condition regexpr)
     describes reservation of cpu functional units (the 3nd operand)
     for instruction which is selected by the condition (the 2nd
     parameter).  The first parameter is used for output of debugging
     information.  The reservations are described by a regular
     expression according the following syntax:

       regexp = regexp "," oneof
              | oneof

       oneof = oneof "|" allof
             | allof

       allof = allof "+" repeat
             | repeat

       repeat = element "*" number
              | element

       element = cpu_function_name
               | reservation_name
               | result_name
               | "nothing"
               | "(" regexp ")"

       1. "," is used for describing start of the next cycle in
          reservation.

       2. "|" is used for describing the reservation described by the
          first regular expression *or* the reservation described by
          the second regular expression *or* etc.

       3. "+" is used for describing the reservation described by the
          first regular expression *and* the reservation described by
          the second regular expression *and* etc.

       4. "*" is used for convenience and simply means sequence in
          which the regular expression are repeated NUMBER times with
          cycle advancing (see ",").

       5. cpu function unit name which means reservation.

       6. reservation name -- see define_reservation.

       7. string "nothing" means no units reservation.

;;      (I FM? I? FM? | FM? FM?) B? B?

;; where I denotes an integer operation, FM a floating-point or media
;; operation, and B a branch operation.  There are two units for each type
;; of instruction: I0 and I1, FM0 and FM1, and B0 and B1.  Units are
;; allocated left-to-right: the first integer instruction uses I0, the
;; second uses I1, and so on.

;; The FR400 is similar to the FR500 except that it allows only 2 operations
;; per packet and has only one branch unit.  We can use the FR500 conflict
;; description for the FR400, but need to define different cpu_units
;; later.

;; Slot/unit combinations available on the FR400 and above:

;; :: 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)])

;; Note - it is the backend's responsibility to fill any unfilled delay slots
;; at assembler generation time.  This is usually done by adding a special print
;; operand to the delayed instruction, and then in the PRINT_OPERAND function
;; calling dbr_sequence_length() to determine how many delay slots were filled.
;; For example:
;;
;; --------------<machine>.md-----------------
;; (define_insn "call"
;;  [(call (match_operand 0 "memory_operand" "m")
;;         (match_operand 1 "" ""))]
;;   ""
;;   "call_delayed %0,%1,%2%#"
;;  [(set_attr "length" "4")
;;   (set_attr "type" "call")])
;;
;; -------------<machine>.h-------------------
;; #define PRINT_OPERAND_PUNCT_VALID_P(CODE) (CODE == '#')
;;
;;  ------------<machine>.c------------------
;; void
;; machine_print_operand (file, x, code)
;;     FILE * file;
;;     rtx    x;
;;     int    code;
;; {
;;   switch (code)
;;   {
;;   case '#':
;;     if (dbr_sequence_length () == 0)
;;       fputs ("\n\tnop", file);
;;     return;

;; :: Notes on Patterns
;; ::
;; ::::::::::::::::::::

;; If you need to construct a sequence of assembler instructions in order
;; to implement a pattern be sure to escape any backslashes and double quotes
;; that you use, eg:
;;
;; (define_insn "an example"
;;   [(some rtl)]
;;   ""
;;   "*
;;    { static char buffer [100];
;;      sprintf (buffer, \"insn \\t %d\", REGNO (operands[1]));
;;      return buffer;
;;    }"
;; )
;;
;; Also if there is more than one instruction, they can be separated by \\;
;; which is a space saving synonym for \\n\\t:
;;
;; (define_insn "another example"
;;   [(some rtl)]
;;   ""
;;   "*
;;    { static char buffer [100];
;;      sprintf (buffer, \"insn1 \\t %d\\;insn2 \\t %%1\",
;;        REGNO (operands[1]));
;;      return buffer;
;;    }"
;; )

;; ::
;; :: 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.

;; 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.
