| 23 | /* This is description of pipeline hazards based on DFA. The | |
| 24 | following constructions can be used for this: | |
| 25 | ||
| 26 | o define_cpu_unit string [string]) describes a cpu functional unit | |
| 27 | (separated by comma). | |
| 28 | ||
| 29 | 1st operand: Names of cpu function units. | |
| 30 | 2nd operand: Name of automaton (see comments for | |
| 31 | DEFINE_AUTOMATON). | |
| 32 | ||
| 33 | All define_reservations and define_cpu_units should have unique | |
| 34 | names which can not be "nothing". | |
| 35 | ||
| 36 | o (exclusion_set string string) means that each CPU function unit | |
| 37 | in the first string can not be reserved simultaneously with each | |
| 38 | unit whose name is in the second string and vise versa. CPU | |
| 39 | units in the string are separated by commas. For example, it is | |
| 40 | useful for description CPU with fully pipelined floating point | |
| 41 | functional unit which can execute simultaneously only single | |
| 42 | floating point insns or only double floating point insns. | |
| 43 | ||
| 44 | o (presence_set string string) means that each CPU function unit in | |
| 45 | the first string can not be reserved unless at least one of | |
| 46 | pattern of units whose names are in the second string is | |
| 47 | reserved. This is an asymmetric relation. CPU units or unit | |
| 48 | patterns in the strings are separated by commas. Pattern is one | |
| 49 | unit name or unit names separated by white-spaces. | |
| 50 | ||
| 51 | For example, it is useful for description that slot1 is reserved | |
| 52 | after slot0 reservation for a VLIW processor. We could describe | |
| 53 | it by the following construction | |
| 54 | ||
| 55 | (presence_set "slot1" "slot0") | |
| 56 | ||
| 57 | Or slot1 is reserved only after slot0 and unit b0 reservation. | |
| 58 | In this case we could write | |
| 59 | ||
| 60 | (presence_set "slot1" "slot0 b0") | |
| 61 | ||
| 62 | All CPU functional units in a set should belong to the same | |
| 63 | automaton. | |
| 64 | ||
| 65 | o (final_presence_set string string) is analogous to | |
| 66 | `presence_set'. The difference between them is when checking is | |
| 67 | done. When an instruction is issued in given automaton state | |
| 68 | reflecting all current and planned unit reservations, the | |
| 69 | automaton state is changed. The first state is a source state, | |
| 70 | the second one is a result state. Checking for `presence_set' is | |
| 71 | done on the source state reservation, checking for | |
| 72 | `final_presence_set' is done on the result reservation. This | |
| 73 | construction is useful to describe a reservation which is | |
| 74 | actually two subsequent reservations. For example, if we use | |
| 75 | ||
| 76 | (presence_set "slot1" "slot0") | |
| 77 | ||
| 78 | the following insn will be never issued (because slot1 requires | |
| 79 | slot0 which is absent in the source state). | |
| 80 | ||
| 81 | (define_reservation "insn_and_nop" "slot0 + slot1") | |
| 82 | ||
| 83 | but it can be issued if we use analogous `final_presence_set'. | |
| 84 | ||
| 85 | o (absence_set string string) means that each CPU function unit in | |
| 86 | the first string can be reserved only if each pattern of units | |
| 87 | whose names are in the second string is not reserved. This is an | |
| 88 | asymmetric relation (actually exclusion set is analogous to this | |
| 89 | one but it is symmetric). CPU units or unit patterns in the | |
| 90 | string are separated by commas. Pattern is one unit name or unit | |
| 91 | names separated by white-spaces. | |
| 92 | ||
| 93 | For example, it is useful for description that slot0 can not be | |
| 94 | reserved after slot1 or slot2 reservation for a VLIW processor. | |
| 95 | We could describe it by the following construction | |
| 96 | ||
| 97 | (absence_set "slot2" "slot0, slot1") | |
| 98 | ||
| 99 | Or slot2 can not be reserved if slot0 and unit b0 are reserved or | |
| 100 | slot1 and unit b1 are reserved . In this case we could write | |
| 101 | ||
| 102 | (absence_set "slot2" "slot0 b0, slot1 b1") | |
| 103 | ||
| 104 | All CPU functional units in a set should to belong the same | |
| 105 | automaton. | |
| 106 | ||
| 107 | o (final_absence_set string string) is analogous to `absence_set' but | |
| 108 | checking is done on the result (state) reservation. See comments | |
| 109 | for final_presence_set. | |
| 110 | ||
| 111 | o (define_bypass number out_insn_names in_insn_names) names bypass with | |
| 112 | given latency (the first number) from insns given by the first | |
| 113 | string (see define_insn_reservation) into insns given by the | |
| 114 | second string. Insn names in the strings are separated by | |
| 115 | commas. | |
| 116 | ||
| 117 | o (define_automaton string) describes names of an automaton | |
| 118 | generated and used for pipeline hazards recognition. The names | |
| 119 | are separated by comma. Actually it is possibly to generate the | |
| 120 | single automaton but unfortunately it can be very large. If we | |
| 121 | use more one automata, the summary size of the automata usually | |
| 122 | is less than the single one. The automaton name is used in | |
| 123 | define_cpu_unit. All automata should have unique names. | |
| 124 | ||
| 125 | o (automata_option string) describes option for generation of | |
| 126 | automata. Currently there are the following options: | |
| 127 | ||
| 128 | o "no-minimization" which makes no minimization of automata. | |
| 129 | This is only worth to do when we are debugging the description | |
| 130 | and need to look more accurately at reservations of states. | |
| 131 | ||
| 132 | o "ndfa" which makes automata with nondetermenistic reservation | |
| 133 | by insns. | |
| 134 | ||
| 135 | o (define_reservation string string) names reservation (the first | |
| 136 | string) of cpu functional units (the 2nd string). Sometimes unit | |
| 137 | reservations for different insns contain common parts. In such | |
| 138 | case, you describe common part and use one its name (the 1st | |
| 139 | parameter) in regular expression in define_insn_reservation. All | |
| 140 | define_reservations, define results and define_cpu_units should | |
| 141 | have unique names which can not be "nothing". | |
| 142 | ||
| 143 | o (define_insn_reservation name default_latency condition regexpr) | |
| 144 | describes reservation of cpu functional units (the 3nd operand) | |
| 145 | for instruction which is selected by the condition (the 2nd | |
| 146 | parameter). The first parameter is used for output of debugging | |
| 147 | information. The reservations are described by a regular | |
| 148 | expression according the following syntax: | |
| 149 | ||
| 150 | regexp = regexp "," oneof | |
| 151 | | oneof | |
| 152 | ||
| 153 | oneof = oneof "|" allof | |
| 154 | | allof | |
| 155 | ||
| 156 | allof = allof "+" repeat | |
| 157 | | repeat | |
| 158 | ||
| 159 | repeat = element "*" number | |
| 160 | | element | |
| 161 | ||
| 162 | element = cpu_function_name | |
| 163 | | reservation_name | |
| 164 | | result_name | |
| 165 | | "nothing" | |
| 166 | | "(" regexp ")" | |
| 167 | ||
| 168 | 1. "," is used for describing start of the next cycle in | |
| 169 | reservation. | |
| 170 | ||
| 171 | 2. "|" is used for describing the reservation described by the | |
| 172 | first regular expression *or* the reservation described by | |
| 173 | the second regular expression *or* etc. | |
| 174 | ||
| 175 | 3. "+" is used for describing the reservation described by the | |
| 176 | first regular expression *and* the reservation described by | |
| 177 | the second regular expression *and* etc. | |
| 178 | ||
| 2a43945f | 179 | 4. "*" is used for convenience and simply means sequence in |
| 30028c85 VM |
180 | which the regular expression are repeated NUMBER times with |
| 181 | cycle advancing (see ","). | |
| 182 | ||
| 183 | 5. cpu function unit name which means reservation. | |
| 184 | ||
| 185 | 6. reservation name -- see define_reservation. | |
| 186 | ||
| 187 | 7. string "nothing" means no units reservation. | |
