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 + pattern of units whose names are in the second string is + reserved. This is an asymmetric relation. CPU units or unit + patterns in the strings are separated by commas. Pattern is one + unit name or unit names separated by white-spaces. + + For example, it is useful for description that slot1 is reserved + after slot0 reservation for a VLIW processor. We could describe + it by the following construction + + (presence_set "slot1" "slot0") + + Or slot1 is reserved only after slot0 and unit b0 reservation. + In this case we could write + + (presence_set "slot1" "slot0 b0") + + All CPU functional units in a set should belong to the same + automaton. + + o (final_presence_set string string) is analogous to + `presence_set'. The difference between them is when checking is + done. When an instruction is issued in given automaton state + reflecting all current and planned unit reservations, the + automaton state is changed. The first state is a source state, + the second one is a result state. Checking for `presence_set' is + done on the source state reservation, checking for + `final_presence_set' is done on the result reservation. This + construction is useful to describe a reservation which is + actually two subsequent reservations. For example, if we use + + (presence_set "slot1" "slot0") + + the following insn will be never issued (because slot1 requires + slot0 which is absent in the source state). + + (define_reservation "insn_and_nop" "slot0 + slot1") + + but it can be issued if we use analogous `final_presence_set'. + + o (absence_set string string) means that each CPU function unit in + the first string can be reserved only if each pattern of units + whose names are 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 or unit patterns in the + string are separated by commas. Pattern is one unit name or unit + names separated by white-spaces. + + For example, it is useful for description that slot0 can not be + reserved after slot1 or slot2 reservation for a VLIW processor. + We could describe it by the following construction + + (absence_set "slot2" "slot0, slot1") + + Or slot2 can not be reserved if slot0 and unit b0 are reserved or + slot1 and unit b1 are reserved . In this case we could write + + (absence_set "slot2" "slot0 b0, slot1 b1") + + All CPU functional units in a set should to belong the same + automaton. + + o (final_absence_set string string) is analogous to `absence_set' but + checking is done on the result (state) reservation. See comments + for final_presence_set. + + 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 (automata_option string) describes option for generation of + automata. Currently there are the following options: + + o "no-minimization" which makes no minimization of automata. + This is only worth to do when we are debugging the description + and need to look more accurately at reservations of states. + + o "ndfa" which makes automata with nondetermenistic reservation + by insns. + + 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. + +*/ + +(define_automaton "one") + +;; All possible combinations of bundles/syllables +(define_cpu_unit "1_0m.ii, 1_0m.mi, 1_0m.fi, 1_0m.mf, 1_0b.bb, 1_0m.bb,\ + 1_0m.ib, 1_0m.mb, 1_0m.fb, 1_0m.lx" "one") +(define_cpu_unit "1_0mi.i, 1_0mm.i, 1_0mf.i, 1_0mm.f, 1_0bb.b, 1_0mb.b,\ + 1_0mi.b, 1_0mm.b, 1_0mf.b, 1_0mlx."
