(define_attr “acc_group” “none,even,odd” (symbol_ref “(enum attr_acc_group) frv_acc_group (insn)”)) ;; Scheduling and Packing Overview ;; ------------------------------- ;; ;; FR-V instructions are divided into five groups: integer, floating-point, ;; media, branch and control. Each group is associated with a separate set ;; of processing units, the number and behavior of which depend on the target ;; target processor. Integer units have names like I0 and I1, floating-point ;; units have names like F0 and F1, and so on. ;; ;; Each member of the FR-V family has its own restrictions on which ;; instructions can issue to which units. For example, some processors ;; allow loads to issue to I0 or I1 while others only allow them to issue ;; to I0. As well as these processor-specific restrictions, there is a ;; general rule that an instruction can only issue to unit X + 1 if an ;; instruction in the same packet issued to unit X. ;; ;; Sometimes the only way to honor these restrictions is by adding nops ;; to a packet. For example, on the fr550, media instructions that access ;; ACC4-7 can only issue to M1 or M3. It is therefore only possible to ;; execute these instructions by packing them with something that issues ;; to M0. When no useful M0 instruction exists, an “mnop” can be used ;; instead. ;; ;; Having decided which instructions should issue to which units, the packet ;; should be ordered according to the following template: ;; ;; I0 F0/M0 I1 F1/M1 .... B0 B1 ... ;; ;; Note that VLIW packets execute strictly in parallel. Every instruction ;; in the packet will stall until all input operands are ready. These ;; operands are then read simultaneously before any registers are modified. ;; This means that it‘s OK to have write-after-read hazards between ;; instructions in the same packet, even if the write is listed earlier ;; than the read. ;; ;; Three gcc passes are involved in generating VLIW packets: ;; ;; (1) The scheduler. This pass uses the standard scheduling code and ;; behaves in much the same way as it would for a superscalar RISC ;; architecture. ;; ;; (2) frv_reorg. This pass inserts nops into packets in order to meet ;; the processor’s issue requirements. It also has code to optimize ;; the type of padding used to align labels. ;; ;; (3) frv_pack_insns. The final packing phase, which puts the ;; instructions into assembly language order according to the ;; “I0 F0/M0 ...” template above. ;; ;; In the ideal case, these three passes will agree on which instructions ;; should be packed together, but this won‘t always happen. In particular: ;; ;; (a) (2) might not pack predicated instructions in the same way as (1). ;; The scheduler tries to schedule predicated instructions for the ;; worst case, assuming the predicate is true. However, if we have ;; something like a predicated load, it isn’t always possible to ;; fill the load delay with useful instructions. (2) should then ;; pack the user of the loaded value as aggressively as possible, ;; in order to optimize the case when the predicate is false. ;; See frv_pack_insn_p for more details. ;; ;; (b) The final shorten_branches pass runs between (2) and (3). ;; Since (2) inserts nops, it is possible that some branches ;; that were thought to be in range during (2) turned out to ;; out-of-range in (3). ;; ;; All three passes use DFAs to model issue restrictions. The main ;; question that the DFAs are supposed to answer is simply: can these ;; instructions be packed together? The DFAs are not responsible for ;; assigning instructions to execution units; that‘s the job of ;; frv_sort_insn_group, see below for details. ;; ;; To get the best results, the DFAs should try to allow packets to ;; be built in every possible order. This gives the scheduler more ;; flexibility, removing the need for things like multipass lookahead. ;; It also means we can take more advantage of inter-packet dependencies. ;; ;; For example, suppose we’re compiling for the fr400 and we have: ;; ;; addi gr4,#1,gr5 ;; ldi @(gr6,gr0),gr4 ;; ;; We can pack these instructions together by assigning the load to I0 and ;; the addition to I1. However, because of the anti dependence between the ;; two instructions, the scheduler must schedule the addition first. ;; We should generally get better schedules if the DFA allows both ;; (ldi, addi) and (addi, ldi), leaving the final packing pass to ;; reorder the packet where appropriate. ;; ;; Almost all integer instructions can issue to any unit in the range I0 ;; to Ix, where the value of “x” depends on the type of instruction and ;; on the target processor. The rules for other instruction groups are ;; usually similar. ;; ;; When the restrictions are as regular as this, we can get the desired ;; behavior by claiming the DFA unit associated with the highest unused ;; execution unit. For example, if an instruction can issue to I0 or I1, ;; the DFA first tries to take the DFA unit associated with I1, and will ;; only take I0‘s unit if I1 isn’t free. (Note that, as mentioned above, ;; the DFA does not assign instructions to units. An instruction that ;; claims DFA unit I1 will not necessarily issue to I1 in the final packet.) ;; ;; There are some cases, such as the fr550 media restriction mentioned ;; above, where the rule is not as simple as “any unit between 0 and X”. ;; Even so, allocating higher units first brings us close to the ideal. ;; ;; Having divided instructions into packets, passes (2) and (3) must ;; assign instructions to specific execution units. They do this using ;; the following algorithm: ;; ;; 1. Partition the instructions into groups (integer, float/media, etc.) ;; ;; 2. For each group of instructions: ;; ;; (a) Issue each instruction in the reset DFA state and use the ;; DFA cpu_unit_query interface to find out which unit it picks ;; first. ;; ;; (b) Sort the instructions into ascending order of picked units. ;; Instructions that pick I1 first come after those that pick ;; I0 first, and so on. Let S be the sorted sequence and S[i] ;; be the ith element of it (counting from zero). ;; ;; (c) If this is the control or branch group, goto (i) ;; ;; (d) Find the largest L such that S[0]...S[L-1] can be issued ;; consecutively from the reset state and such that the DFA ;; claims unit X when S[X] is added. Let D be the DFA state ;; after instructions S[0]...S[L-1] have been issued. ;; ;; (e) If L is the length of S, goto (i) ;; ;; (f) Let U be the number of units belonging to this group and #S be ;; the length of S. Create a new sequence S' by concatenating ;; S[L]...S[#S-1] and (U - #S) nops. ;; ;; (g) For each permutation S'' of S', try issuing S'' from last to ;; first, starting with state D. See if the DFA claims unit ;; X + L when each S''[X] is added. If so, set S to the ;; concatenation of S[0]...S[L-1] and S'', then goto (i). ;; ;; (h) If (g) found no permutation, abort. ;; ;; (i) S is now the sorted sequence for this group, meaning that S[X] ;; issues to unit X. Trim any unwanted nops from the end of S. ;; ;; The sequence calculated by (b) is trivially correct for control ;; instructions since they can‘t be packed. It is also correct for branch ;; instructions due to their simple issue requirements. For integer and ;; floating-point/media instructions, the sequence calculated by (b) is ;; often the correct answer; the rest of the algorithm is optimized for ;; the case in which it is correct. ;; ;; If there were no irregularities in the issue restrictions then step ;; (d) would not be needed. It is mainly there to cope with the fr550 ;; integer restrictions, where a store can issue to I1, but only if a store ;; also issues to I0. (Note that if a packet has two stores, they will be ;; at the beginning of the sequence calculated by (b).) It also copes ;; with fr400 M-2 instructions, which must issue to M0, and which cannot ;; be issued together with an mnop in M1. ;; ;; Step (g) is the main one for integer and float/media instructions. ;; The first permutation it tries is S’ itself (because, as noted above, ;; the sequence calculated by (b) is often correct). If S' doesn‘t work, ;; the implementation tries varying the beginning of the sequence first. ;; Thus the nops towards the end of the sequence will only move to lower ;; positions if absolutely necessary. ;; ;; The algorithm is theoretically exponential in the number of instructions ;; in a group, although it’s only O(n log(n)) if the sequence calculated by ;; (b) is acceptable. In practice, the algorithm completes quickly even ;; in the rare cases where (g) needs to try other permutations. (define_automaton “integer, float_media, branch, control, idiv, div”)

;; :::::::::::::::::::: ;; :: ;; :: 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: ;; ;; --------------.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”)]) ;; ;; -------------.h------------------- ;; #define PRINT_OPERAND_PUNCT_VALID_P(CODE) (CODE == ‘#’) ;; ;; ------------.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, e.g.: ;; ;; (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; ;; }” ;; ) ;;
(include “predicates.md”) (include “constraints.md”) ;; :::::::::::::::::::: ;; :: ;; :: 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 TARGET_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 TARGET_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.

;; Unfortunately, we do have to separate out load-type moves from the rest, ;; and only allow memory source operands in the former.
