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