38 | package Einfo is | |
39 | ||
40 | -- This package defines the annotations to the abstract syntax tree that | |
41 | -- are needed to support semantic processing of an Ada compilation. | |
42 | ||
82c80734 RD |
43 | -- Note that after editing this spec and the corresponding body it is |
44 | -- required to run ceinfo to check the consistentcy of spec and body. | |
45 | -- See ceinfo.adb for more information about the checks made. | |
46 | ||
70482933 RK |
47 | -- These annotations are for the most part attributes of declared entities, |
48 | -- and they correspond to conventional symbol table information. Other | |
49 | -- attributes include sets of meanings for overloaded names, possible | |
50 | -- types for overloaded expressions, flags to indicate deferred constants, | |
51 | -- incomplete types, etc. These attributes are stored in available fields | |
52 | -- in tree nodes (i.e. fields not used by the parser, as defined by the | |
53 | -- Sinfo package specification), and accessed by means of a set of | |
54 | -- subprograms which define an abstract interface. | |
55 | ||
56 | -- There are two kinds of semantic information | |
57 | ||
58 | -- First, the tree nodes with the following Nkind values: | |
59 | ||
60 | -- N_Defining_Identifier | |
61 | -- N_Defining_Character_Literal | |
62 | -- N_Defining_Operator_Symbol | |
63 | ||
64 | -- are called Entities, and constitute the information that would often | |
65 | -- be stored separately in a symbol table. These nodes are all extended | |
66 | -- to provide extra space, and contain fields which depend on the entity | |
67 | -- kind, as defined by the contents of the Ekind field. The use of the | |
68 | -- Ekind field, and the associated fields in the entity, are defined | |
69 | -- in this package, as are the access functions to these fields. | |
70 | ||
71 | -- Second, in some cases semantic information is stored directly in other | |
72 | -- kinds of nodes, e.g. the Etype field, used to indicate the type of an | |
73 | -- expression. The access functions to these fields are defined in the | |
74 | -- Sinfo package, but their full documentation is to be found in | |
75 | -- the Einfo package specification. | |
76 | ||
77 | -- Declaration processing places information in the nodes of their defining | |
78 | -- identifiers. Name resolution places in all other occurrences of an | |
79 | -- identifier a pointer to the corresponding defining occurrence. | |

82 | -- The XEINFO Utility Program -- | |
83 | -------------------------------- | |
84 | ||
85 | -- XEINFO is a utility program which automatically produces a C header file, | |
6e443c90 RD |
86 | -- einfo.h from the spec and body of package Einfo. It reads the input |
87 | -- files einfo.ads and einfo.adb and produces the output file einfo.h. | |
88 | -- XEINFO is run automatically by the build scripts when you do a full | |
89 | -- bootstrap. | |
70482933 RK |
90 | |
91 | -- In order for this utility program to operate correctly, the form of the | |
92 | -- einfo.ads and einfo.adb files must meet certain requirements and be laid | |
93 | -- out in a specific manner. | |
94 | ||
95 | -- The general form of einfo.ads is as follows: | |
96 | ||
97 | -- type declaration for type Entity_Kind | |
98 | -- subtype declarations declaring subranges of Entity_Kind | |
99 | -- subtype declarations declaring synonyms for some standard types | |
100 | -- function specs for attributes | |
101 | -- procedure specs | |
102 | -- pragma Inline declarations | |
103 | ||
104 | -- This order must be observed. There are no restrictions on the procedures, | |
105 | -- since the C header file only includes functions (Gigi is not allowed to | |
106 | -- modify the generated tree). However, functions are required to have headers | |
107 | -- that fit on a single line. | |
108 | ||
109 | -- XEINFO reads and processes the function specs and the pragma Inlines. For | |
110 | -- functions that are declared as inlined, XEINFO reads the corresponding body | |
6e443c90 | 111 | -- from einfo.adb, and processes it into C code. This results in some strict |
70482933 RK |
112 | -- restrictions on which functions can be inlined: |
113 | ||
114 | -- The function spec must be on a single line | |
115 | ||
116 | -- There can only be a single statement, contained on a single line, | |
117 | -- not counting any pragma Assert statements. | |
118 | ||
edd63e9b | 119 | -- This single statement must either be a function call with simple, |
70482933 RK |
120 | -- single token arguments, or it must be a membership test of the form |
121 | -- a in b, where a and b are single tokens. | |
122 | ||
123 | -- For functions that are not inlined, there is no restriction on the body, | |
124 | -- and XEINFO generates a direct reference in the C header file which allows | |
125 | -- the C code in Gigi to directly call the corresponding Ada body. | |

128 | -- Handling of Type'Size Values -- | |
129 | ---------------------------------- | |
130 | ||
131 | -- The Ada 95 RM contains some rather peculiar (to us!) rules on the value | |
132 | -- of type'Size (see RM 13.3(55)). We have found that attempting to use | |
133 | -- these RM Size values generally, and in particular for determining the | |
134 | -- default size of objects, creates chaos, and major incompatibilies in | |
135 | -- existing code. | |
136 | ||
137 | -- We proceed as follows, for discrete and fixed-point subtypes, we have | |
138 | -- two separate sizes for each subtype: | |
139 | ||
140 | -- The Object_Size, which is used for determining the default size of | |
141 | -- objects and components. This size value can be referred to using the | |
142 | -- Object_Size attribute. The phrase "is used" here means that it is | |
143 | -- the basis of the determination of the size. The backend is free to | |
144 | -- pad this up if necessary for efficiency, e.g. an 8-bit stand-alone | |
145 | -- character might be stored in 32 bits on a machine with no efficient | |
146 | -- byte access instructions such as the Alpha. | |
147 | ||
148 | -- The default rules for the value of Object_Size for fixed-point and | |
149 | -- discrete types are as follows: | |
150 | ||
151 | -- The Object_Size for base subtypes reflect the natural hardware | |
152 | -- size in bits (see Ttypes and Cstand for integer types). For | |
153 | -- enumeration and fixed-point base subtypes have 8. 16. 32 or 64 | |
154 | -- bits for this size, depending on the range of values to be stored. | |
155 | ||
156 | -- The Object_Size of a subtype is the same as the Object_Size of | |
157 | -- the subtype from which it is obtained. | |
158 | ||
159 | -- The Object_Size of a derived base type is copied from the parent | |
160 | -- base type, and the Object_Size of a derived first subtype is copied | |
161 | -- from the parent first subtype. | |
162 | ||
163 | -- The Value_Size which is the number of bits required to store a value | |
164 | -- of the type. This size can be referred to using the Value_Size | |
165 | -- attribute. This value is used to determine how tightly to pack | |
166 | -- records or arrays with components of this type, and also affects | |
167 | -- the semantics of unchecked conversion (unchecked conversions where | |
168 | -- the Value_Size values differ generate a warning, and are potentially | |
169 | -- target dependent). | |
170 | ||
171 | -- The default rule for the value of Value_Size are as follows: | |
172 | ||
173 | -- The Value_Size for a base subtype is the minimum number of bits | |
174 | -- required to store all values of the type (including the sign bit | |
175 | -- only if negative values are possible). | |
176 | ||
177 | -- If a subtype statically matches the first subtype, then it has | |
178 | -- by default the same Value_Size as the first subtype. This is a | |
179 | -- consequence of RM 13.1(14) ("if two subtypes statically match, | |
180 | -- then their subtype-specific aspects are the same".) | |
181 | ||
182 | -- All other subtypes have a Value_Size corresponding to the minimum | |
183 | -- number of bits required to store all values of the subtype. For | |
184 | -- dynamic bounds, it is assumed that the value can range down or up | |
185 | -- to the corresponding bound of the ancestor | |
186 | ||
10b93b2e | 187 | -- The RM defined attribute Size corresponds to the Value_Size attribute |
70482933 RK |
188 | |
189 | -- The Size attribute may be defined for a first-named subtype. This sets | |
190 | -- the Value_Size of the first-named subtype to the given value, and the | |
191 | -- Object_Size of this first-named subtype to the given value padded up | |
192 | -- to an appropriate boundary. It is a consequence of the default rules | |
193 | -- above that this Object_Size will apply to all further subtypes. On the | |
5d37ba92 | 194 | -- other hand, Value_Size is affected only for the first subtype, any |
70482933 RK |
195 | -- dynamic subtypes obtained from it directly, and any statically matching |
196 | -- subtypes. The Value_Size of any other static subtypes is not affected. | |
197 | ||
198 | -- Value_Size and Object_Size may be explicitly set for any subtype using | |
199 | -- an attribute definition clause. Note that the use of these attributes | |
200 | -- can cause the RM 13.1(14) rule to be violated. If two access types | |
201 | -- reference aliased objects whose subtypes have differing Object_Size | |
202 | -- values as a result of explicit attribute definition clauses, then it | |
203 | -- is erroneous to convert from one access subtype to the other. | |
204 | ||
205 | -- At the implementation level, Esize stores the Object_Size and the | |
206 | -- RM_Size field stores the Value_Size (and hence the value of the | |
207 | -- Size attribute, which, as noted above, is equivalent to Value_Size). | |
208 | ||
209 | -- To get a feel for the difference, consider the following examples (note | |
210 | -- that in each case the base is short_short_integer with a size of 8): | |
211 | ||
212 | -- Object_Size Value_Size | |
213 | ||
214 | -- type x1 is range 0..5; 8 3 | |
215 | ||
216 | -- type x2 is range 0..5; | |
217 | -- for x2'size use 12; 12 12 | |
218 | ||
219 | -- subtype x3 is x2 range 0 .. 3; 12 2 | |
220 | ||
221 | -- subtype x4 is x2'base range 0 .. 10; 8 4 | |
222 | ||
223 | -- subtype x5 is x2 range 0 .. dynamic; 12 (7) | |
224 | ||
225 | -- subtype x6 is x2'base range 0 .. dynamic; 8 (7) | |
226 | ||
227 | -- Note: the entries marked (7) are not actually specified by the Ada 95 RM, | |
228 | -- but it seems in the spirit of the RM rules to allocate the minimum number | |
229 | -- of bits known to be large enough to hold the given range of values. | |
230 | ||
231 | -- So far, so good, but GNAT has to obey the RM rules, so the question is | |
232 | -- under what conditions must the RM Size be used. The following is a list | |
233 | -- of the occasions on which the RM Size must be used: | |
234 | ||
235 | -- Component size for packed arrays or records | |
236 | -- Value of the attribute Size for a type | |
237 | -- Warning about sizes not matching for unchecked conversion | |
238 | ||
239 | -- The RM_Size field keeps track of the RM Size as needed in these | |
240 | -- three situations. | |
241 | ||
242 | -- For types other than discrete and fixed-point types, the Object_Size | |
243 | -- and Value_Size are the same (and equivalent to the RM attribute Size). | |
244 | -- Only Size may be specified for such types. | |
245 | ||
5d37ba92 ES |
246 | -- All size attributes are stored as Uint values. Negative values are used to |
247 | -- reference GCC expressions for the case of non-static sizes, as explained | |
248 | -- in Repinfo. | |

251 | -- Entity Attributes -- | |
252 | ----------------------- | |
253 | ||
254 | -- This section contains a complete list of the attributes that are defined | |
255 | -- on entities. Some attributes apply to all entities, others only to certain | |
256 | -- kinds of entities. In the latter case the attribute should only be set or | |
257 | -- accessed if the Ekind field indicates an appropriate entity. | |
258 | ||
259 | -- There are two kinds of attributes that apply to entities, stored and | |
260 | -- synthesized. Stored attributes correspond to a field or flag in the entity | |
261 | -- itself. Such attributes are identified in the table below by giving the | |
262 | -- field or flag in the attribute that is used to hold the attribute value. | |
263 | -- Synthesized attributes are not stored directly, but are rather computed as | |
264 | -- needed from other attributes, or from information in the tree. These are | |
265 | -- marked "synthesized" in the table below. The stored attributes have both | |
266 | -- access functions and set procedures to set the corresponding values, while | |
267 | -- synthesized attributes have only access functions. | |
268 | ||
269 | -- Note: in the case of Node, Uint, or Elist fields, there are cases where | |
270 | -- the same physical field is used for different purposes in different | |
271 | -- entities, so these access functions should only be referenced for the | |
272 | -- class of entities in which they are defined as being present. Flags are | |
273 | -- not overlapped in this way, but nevertheless as a matter of style and | |
274 | -- abstraction (which may or may not be checked by assertions in the body), | |
275 | -- this restriction should be observed for flag fields as well. | |
276 | ||
277 | -- Note: certain of the attributes on types apply only to base types, and | |
278 | -- are so noted by the notation [base type only]. These are cases where the | |
279 | -- attribute of any subtype is the same as the attribute of the base type. | |
280 | -- The attribute can be referenced on a subtype (and automatically retrieves | |
07fc65c4 GB |
281 | -- the value from the base type). However, it is an error to try to set the |
282 | -- attribute on other than the base type, and if assertions are enabled, | |
283 | -- an attempt to set the attribute on a subtype will raise an assert error. | |
70482933 | 284 | |
21d27997 RD |
285 | -- Other attributes are noted as applying to the [implementation base type |
286 | -- only]. These are representation attributes which must always apply to a | |
287 | -- full non-private type, and where the attributes are always on the full | |
288 | -- type. The attribute can be referenced on a subtype (and automatically | |
289 | -- retries the value from the implementation base type). However, it is an | |
290 | -- error to try to set the attribute on other than the implementation base | |
291 | -- type, and if assertions are enabled, an attempt to set the attribute on a | |
07fc65c4 | 292 | -- subtype will raise an assert error. |
70482933 RK |
293 | |
294 | -- Accept_Address (Elist21) | |
295 | -- Present in entries. If an accept has a statement sequence, then an | |
296 | -- address variable is created, which is used to hold the address of the | |
297 | -- parameters, as passed by the runtime. Accept_Address holds an element | |
298 | -- list which represents a stack of entities for these address variables. | |
299 | -- The current entry is the top of the stack, which is the last element | |
300 | -- on the list. A stack is required to handle the case of nested select | |
301 | -- statements referencing the same entry. | |
302 | ||
303 | -- Actual_Subtype (Node17) | |
304 | -- Present in variables, constants, and formal parameters. This is the | |
305 | -- subtype imposed by the value of the object, as opposed to its nominal | |
306 | -- subtype, which is imposed by the declaration. The actual subtype | |
307 | -- differs from the nominal one when the latter is indefinite (as in the | |
308 | -- case of an unconstrained formal parameter, or a variable declared | |
309 | -- with an unconstrained type and an initial value). The nominal subtype | |
310 | -- is the Etype entry for the entity. The Actual_Subtype field is set | |
311 | -- only if the actual subtype differs from the nominal subtype. If the | |
312 | -- actual and nominal subtypes are the same, then the Actual_Subtype | |
313 | -- field is Empty, and Etype indicates both types. | |
980f237d | 314 | -- |
70482933 RK |
315 | -- For objects, the Actual_Subtype is set only if this is a discriminated |
316 | -- type. For arrays, the bounds of the expression are obtained and the | |
317 | -- Etype of the object is directly the constrained subtype. This is | |
318 | -- rather irregular, and the semantic checks that depend on the nominal | |
319 | -- subtype being unconstrained use flag Is_Constr_Subt_For_U_Nominal(qv). | |
320 | ||
a9d8907c | 321 | -- Access_Disp_Table (Elist16) [implementation base type only] |
70482933 | 322 | -- Present in record type entities. For a tagged type, points to the |
0f282086 RD |
323 | -- dispatch tables associated with the tagged type. The first two |
324 | -- entities correspond with the primary dispatch table: 1) primary | |
325 | -- dispatch table with user-defined primitives, 2) primary dispatch table | |
326 | -- with predefined primitives. For each interface type covered by the | |
327 | -- tagged type we also have: 3) secondary dispatch table with thunks of | |
328 | -- primitives covering user-defined interface primitives, 4) secondary | |
329 | -- dispatch table with thunks of predefined primitives, 5) secondary | |
330 | -- dispatch table with user-defined primitives, and 6) secondary dispatch | |
331 | -- table with predefined primitives. The last entity of this list is an | |
332 | -- access type declaration used to expand dispatching calls through the | |
333 | -- primary dispatch table. For a non-tagged record, contains Empty. | |

335 | -- Address_Clause (synthesized) | |
336 | -- Applies to entries, objects and subprograms. Set if an address clause | |
337 | -- is present which references the object or subprogram and points to | |
338 | -- the N_Attribute_Definition_Clause node. Empty if no Address clause. | |
339 | -- The expression in the address clause is always a constant that is | |
340 | -- defined before the entity to which the address clause applies. | |
341 | -- Note: Gigi references this field in E_Task_Type entities??? | |
342 | ||
343 | -- Address_Taken (Flag104) | |
344 | -- Present in all entities. Set if the Address or Unrestricted_Access | |
345 | -- attribute is applied directly to the entity, i.e. the entity is the | |
346 | -- entity of the prefix of the attribute reference. Used by Gigi to | |
5d37ba92 ES |
347 | -- make sure that the address can be meaningfully taken, and also in |
348 | -- the case of subprograms to control output of certain warnings. | |
70482933 RK |
349 | |
350 | -- Alias (Node18) | |
6e443c90 RD |
351 | -- Present in overloaded entities (literals, subprograms, entries) and |
352 | -- subprograms that cover a primitive operation of an abstract interface | |
ce2b6ba5 JM |
353 | -- (that is, subprograms with the Interface_Alias attribute). In case of |
354 | -- overloaded entities it points to the parent subprogram of a derived | |
355 | -- subprogram. In case of abstract interface subprograms it points to the | |
356 | -- subprogram that covers the abstract interface primitive. Also used for | |
357 | -- a subprogram renaming, where it points to the renamed subprogram. | |
358 | -- Always empty for entries. | |

360 | -- Alignment (Uint14) | |
0a36105d JM |
361 | -- Present in entities for types and also in constants, variables |
362 | -- (including exceptions where it refers to the static data allocated for | |
363 | -- an exception), loop parameters, and formal parameters. This indicates | |
364 | -- the desired alignment for a type, or the actual alignment for an | |
365 | -- object. A value of zero (Uint_0) indicates that the alignment has not | |
366 | -- been set yet. The alignment can be set by an explicit alignment | |
367 | -- clause, or set by the front-end in package Layout, or set by the | |
368 | -- back-end as part of the back end back-annotation process. The | |
369 | -- alignment field is also present in E_Exception entities, but there it | |
370 | -- is used only by the back-end for back annotation. | |
70482933 RK |
371 | |
372 | -- Alignment_Clause (synthesized) | |
ba673907 | 373 | -- Applies to all entities for types and objects. If an alignment |
70482933 RK |
374 | -- attribute definition clause is present for the entity, then this |
375 | -- function returns the N_Attribute_Definition clause that specifies the | |
376 | -- alignment. If no alignment clause applies to the type, then the call | |
377 | -- to this function returns Empty. Note that the call can return a | |
378 | -- non-Empty value even if Has_Alignment_Clause is not set (happens with | |
379 | -- subtype and derived type declarations). Note also that a record | |
380 | -- definition clause with an (obsolescent) mod clause is converted | |
381 | -- into an attribute definition clause for this purpose. | |
382 | ||
70482933 RK |
383 | -- Associated_Formal_Package (Node12) |
384 | -- Present in packages that are the actuals of formal_packages. Points | |
385 | -- to the entity in the declaration for the formal package. | |
386 | ||
387 | -- Associated_Node_For_Itype (Node8) | |
388 | -- Present in all type and subtype entities. Set non-Empty only for | |
389 | -- Itypes. Set to point to the associated node for the Itype, i.e. | |
390 | -- the node whose elaboration generated the Itype. This is used for | |
ba673907 JM |
391 | -- copying trees, to determine whether or not to copy an Itype, and |
392 | -- also for accessibility checks on anonymous access types. This | |
393 | -- node is typically an object declaration, component declaration, | |
394 | -- type or subtype declaration. For an access discriminant in a type | |
395 | -- declaration, the associated_node_for_itype is the discriminant | |

422 | -- of a private type, it is possible for the base type attribute to | |
423 | -- return a private type, even if the subtype to which it applies is | |
424 | -- non-private. See also Implementation_Base_Type. Note: it is allowed | |

934 | -- this is normally the same as Enumeration_Pos except in the presence | |
935 | -- of representation clauses, where Pos will still represent the | |

942 | -- value for this literal. Empty if no enumeration rep clause for this | |
943 | -- literal (or if rep clause does not have an entry for this literal, | |

948 | -- Present in enumeration types (but not enumeration subtypes). Set to | |
949 | -- Empty unless the enumeration type has a non-standard representation | |
950 | -- (i.e. at least one literal has a representation value different from | |

0f282086 RD |
1049 | -- other foreign-convention types). On many targets, this means that |

2230 | -- Is_Known_Valid (Flag170) |
2231 | -- Present in all entities. Relevant for types (and subtype) and | |
2232 | -- for objects (and enumeration literals) of a discrete type. | |
2233 | -- | |
2234 | -- The purpose of this flag is to implement the requirement stated | |
2235 | -- in (RM 13.9.1(9-11)) which require that the use of possibly invalid | |
2236 | -- values may not cause programs to become erroneous. See the function | |
47cb314a | 2237 | -- Checks.Expr_Known_Valid for further details. Note that the setting |
70482933 RK |
2238 | -- is conservative, in the sense that if the flag is set, it must be |
2239 | -- right. If the flag is not set, nothing is known about the validity. | |
2240 | -- | |
2241 | -- For enumeration literals, the flag is always set, since clearly | |
2242 | -- an enumeration literal represents a valid value. Range checks | |
2243 | -- where necessary will ensure that this valid value is appropriate. | |
2244 | -- | |
2245 | -- For objects, the flag indicates the state of knowledge about the | |
2246 | -- current value of the object. This may be modified during expansion, | |
2247 | -- and thus the final value is not relevant to gigi. | |
2248 | -- | |
2249 | -- For types and subtypes, the flag is set if all possible bit patterns | |
2250 | -- of length Object_Size (i.e. Esize of the type) represent valid values | |
2251 | -- of the type. In general for such tytpes, all values are valid, the | |
2252 | -- only exception being the case where an object of the type has an | |
2253 | -- explicit size that is greater than Object_Size. | |
2254 | -- | |
2255 | -- For non-discrete objects, the setting of the Is_Known_Valid flag is | |
2256 | -- not defined, and is not relevant, since the considerations of the | |
2257 | -- requirement in (RM 13.9.1(9-11)) do not apply. | |
fbf5a39b AC |

fdce4bb7 JM |
2299 | -- Present in all type and subtype entities. It is set in some (but not |
2300 | -- all) cases in which a subtype is known to be non-static. Before this | |
2301 | -- flag was added, the computation of whether a subtype was static was | |
2302 | -- entirely synthesized, by looking at the bounds, and the immediate | |
2303 | -- subtype parent. However, this method does not work for some Itypes | |
2304 | -- that have no parent set (and the only way to find the immediate | |
70482933 RK |
2305 | -- subtype parent is to go through the tree). For now, this flay is set |
2306 | -- conservatively, i.e. if it is set then for sure the subtype is non- | |
2307 | -- static, but if it is not set, then the type may or may not be static. | |
fdce4bb7 JM |
2308 | -- Thus the test for a static subtype is that this flag is clear AND that |
2309 | -- the bounds are static AND that the parent subtype (if available to be | |
2310 | -- tested) is static. Eventually we should make sure this flag is always | |
2311 | -- set right, at which point, these comments can be removed, and the | |

fbf5a39b | 2315 | -- Present in procedure entities. Set for generated init proc procedures |
70482933 RK |
2316 | -- (used to initialize composite types), if the code for the procedure |
2317 | -- is null (i.e. is a return and nothing else). Such null initialization | |
2318 | -- procedures are generated in case some client is compiled using the | |

2362 | -- Is_Packed (Flag51) [implementation base type only] | |
2363 | -- Present in all type entities. This flag is set only for record and | |
2364 | -- array types which have a packed representation. There are three | |
2365 | -- cases which cause packing: | |
2366 | -- | |
2367 | -- 1. Explicit use of pragma Pack for an array of package components | |
2368 | -- 2. Explicit use of pragma Pack to pack a record | |
2369 | -- 4. Setting Component_Size of an array to a bit-packable value | |
2370 | -- 3. Indexing an array with a non-standard enumeration type. | |
2371 | -- | |
2372 | -- For records, Is_Packed is always set if Has_Pack_Pragma is set, | |
2373 | -- and can also be set on its own in a derived type which inherited | |
2374 | -- its packed status. | |
2375 | -- | |
2376 | -- For arrays, Is_Packed is set if an array is bit packed (i.e. the | |
2377 | -- component size is known at compile time and is 1-7, 9-15 or 17-31), | |
2378 | -- or if the array has one or more index types that are enumeration | |
2379 | -- types with non-standard representations (in GNAT, we store such | |

2381 | -- | |
2382 | -- As for the case of records, Is_Packed can be set on its own for a | |
2383 | -- derived type, with the same dual before/after freeze meaning. | |
2384 | -- Is_Packed can also be set as the result of an explicit component | |
2385 | -- size clause that specifies an appropriate component size. | |
2386 | -- | |
2387 | -- In the bit packed array case, Is_Bit_Packed_Array will be set in | |
2388 | -- the bit packed case once the array type is frozen. | |
2389 | -- | |
2390 | -- Before an array type is frozen, Is_Packed will always be set if | |
2391 | -- Has_Pack_Pragma is set. Before the freeze point, it is not possible | |
2392 | -- to know the component size, since the component type is not frozen | |
2393 | -- until the array type is frozen. Thus Is_Packed for an array type | |
2394 | -- before it is frozen means that packed is required. Then if it turns | |
2395 | -- out that the component size is not suitable for bit packing, the | |
2396 | -- Is_Packed flag gets turned off. | |

2402 | -- if the type appears in the Packed_Array_Type field of some other type | |
2403 | -- entity. It is used by Gigi to activate the special processing for such | |
2404 | -- types (unchecked conversions that would not otherwise be allowed are | |
07fc65c4 GB |
2405 | -- allowed for such types). If the Is_Packed_Array_Type flag is set in |

3280 | -- Return_Applies_To (Node8) |
3281 | -- Present in E_Return_Statement. Points to the entity representing | |
3282 | -- the construct to which the return statement applies, as defined in | |

70482933 RK |
3287 | -- Returns_By_Ref (Flag90) |
3288 | -- Present in function entities, to indicate that the function | |
ba673907 | 3289 | -- returns the result by reference, either because its return type is a |
70482933 RK |

07fc65c4 | 3292 | -- Reverse_Bit_Order (Flag164) [base type only] |
70482933 | 3293 | -- Present in all record type entities. Set if a valid pragma an |
e14c931f RW |
3294 | -- attribute representation clause for Bit_Order has reversed the order |
3295 | -- of bits from the default value. When this flag is set, a component | |
3296 | -- clause must specify a set of bits entirely contained in a single | |
3297 | -- storage unit (Ada 95) or a single machine scalar (see Ada 2005 | |
3298 | -- AI-133), or must occupy in integral number of storage units. | |
70482933 RK |
3299 | |
3300 | -- RM_Size (Uint13) | |
3301 | -- Present in all type and subtype entities. Contains the value of | |
3302 | -- type'Size as defined in the RM. See also the Esize field and | |
3303 | -- and the description on "Handling of Type'Size Values". A value | |
9596236a | 3304 | -- of zero in this field for a non-discrete type means that |
70482933 RK |
3305 | -- the front end has not yet determined the size value. For the |
3306 | -- case of a discrete type, this field is always set by the front | |
3307 | -- end and zero is a legitimate value for a type with one value. | |
3308 | ||
3309 | -- Root_Type (synthesized) | |
3310 | -- Applies to all type entities. For class-wide types, return the root | |
3311 | -- type of the class covered by the CW type, otherwise returns the | |
3312 | -- ultimate derivation ancestor of the given type. This function | |
3313 | -- preserves the view, i.e. the Root_Type of a partial view is the | |
e14c931f | 3314 | -- partial view of the ultimate ancestor, the Root_Type of a full view |
70482933 RK |
3315 | -- is the full view of the ultimate ancestor. Note that this function |
3316 | -- does not correspond exactly to the use of root type in the RM, since | |
3317 | -- in the RM root type applies to a class of types, not to a type. | |
3318 | ||
3319 | -- Scalar_Range (Node20) | |
3320 | -- Present in all scalar types (including modular types, where the | |
3321 | -- bounds are 0 .. modulus - 1). References a node in the tree that | |
3322 | -- contains the bounds for the range. Note that this information | |
3323 | -- could be obtained by rummaging around the tree, but it is more | |
3324 | -- convenient to have it immediately at hand in the entity. The | |
3325 | -- contents of Scalar_Range can either be an N_Subtype_Indication | |
3326 | -- node (with a constraint), or a Range node, but not a simple | |
3327 | -- subtype reference (a subtype is converted into a range). | |
3328 | ||
3329 | -- Scale_Value (Uint15) | |
3330 | -- Present in decimal fixed-point types and subtypes. Contains the scale | |
3331 | -- for the type (i.e. the value of type'Scale = the number of decimal | |
3332 | -- digits after the decimal point). | |
3333 | ||
3334 | -- Scope (Node3) | |
3335 | -- Present in all entities. Points to the entity for the scope (block, | |

9d77af56 | 3342 | -- Scope_Depth (synthesized) |
70482933 RK |
3343 | -- Applies to program units, blocks, concurrent types and entries, |
3344 | -- and also to record types, i.e. to any entity that can appear on | |
3345 | -- the scope stack. Yields the scope depth value, which for those | |
3346 | -- entities other than records is simply the scope depth value, | |
3347 | -- for record entities, it is the Scope_Depth of the record scope. | |
3348 | ||
3349 | -- Scope_Depth_Value (Uint22) | |
3350 | -- Present in program units, blocks, concurrent types and entries. | |
3351 | -- Indicates the number of scopes that statically enclose the | |

3353 | -- Note that record types can act as scopes but do NOT have this field | |
3354 | -- set (see Scope_Depth above) | |
3355 | ||
3356 | -- Scope_Depth_Set (synthesized) | |
3357 | -- Applies to a special predicate function that returns a Boolean value | |
3358 | -- indicating whether or not the Scope_Depth field has been set. It | |
3359 | -- is needed, since returns an invalid value in this case! | |

3361 | -- Sec_Stack_Needed_For_Return (Flag167) | |
15ce9ca2 | 3362 | -- Present in scope entities (blocks, functions, procedures, tasks, |
70482933 RK |
3363 | -- entries). Set to True when secondary stack is used to hold |
3364 | -- the returned value of a function and thus should not be | |
3365 | -- released on scope exit. | |
3366 | ||
3367 | -- Shadow_Entities (List14) | |
3368 | -- Present in package and generic package entities. Points to a list | |
3369 | -- of entities that correspond to private types. For each private type | |
3370 | -- a shadow entity is created that holds a copy of the private view. | |
3371 | -- In regions of the program where the full views of these private | |
3372 | -- entities are visible, the full view is copied into the entity that | |
3373 | -- is normally used to hold the private view, but the shadow entity | |
3374 | -- copy is unchanged. The shadow entities are then used to restore the | |
3375 | -- original private views at the end of the region. This list is a | |
3376 | -- standard format list (i.e. First (Shadow_Entities) is the first | |
3377 | -- entry and subsequent entries are obtained using Next. | |

fbf5a39b | 3384 | -- Size_Check_Code (Node19) |
70482933 | 3385 | -- Present in constants and variables. Normally Empty. Set if code is |
fbf5a39b | 3386 | -- generated to check the size of the object. This field is used to |
70482933 RK |
3387 | -- suppress this code if a subsequent address clause is encountered. |
3388 | ||
3389 | -- Size_Clause (synthesized) | |
3390 | -- Applies to all entities. If a size clause is present in the rep | |
3391 | -- item chain for an entity then the attribute definition clause node | |
3392 | -- for the size clause is returned. Otherwise Size_Clause returns Empty | |
3393 | -- if no item is present. Usually this is only meaningful if the flag | |
3394 | -- Has_Size_Clause is set. This is because when the representation item | |
3395 | -- chain is copied for a derived type, it can inherit a size clause that | |
3396 | -- is not applicable to the entity. | |
3397 | ||
3398 | -- Size_Depends_On_Discriminant (Flag177) | |
3399 | -- Present in all entities for types and subtypes. Indicates that the | |
3400 | -- size of the type depends on the value of one or more discriminants. | |
3401 | -- Currently, this flag is only set in front end layout mode for arrays | |
3402 | -- which have one or more bounds depending on a discriminant value. | |
3403 | ||
3404 | -- Size_Known_At_Compile_Time (Flag92) | |
3405 | -- Present in all entities for types and subtypes. Indicates that the | |
3406 | -- size of objects of the type is known at compile time. This flag is | |
3407 | -- used to optimize some generated code sequences, and also to enable | |
3408 | -- some error checks (e.g. disallowing component clauses on variable | |
21d27997 | 3409 | -- length objects). It is set conservatively (i.e. if it is True, the |
70482933 RK |
3410 | -- size is certainly known at compile time, if it is False, then the |
3411 | -- size may or may not be known at compile time, but the code will | |
3412 | -- assume that it is not known). | |
3413 | ||
3414 | -- Small_Value (Ureal21) | |
3415 | -- Present in fixed point types. Points to the universal real for the | |
3416 | -- Small of the type, either as given in a representation clause, or | |
3417 | -- as computed (as a power of two) by the compiler. | |
3418 | ||
3419 | -- Spec_Entity (Node19) | |
3420 | -- Present in package body entities. Points to corresponding package | |
3421 | -- spec entity. Also present in subprogram body parameters in the | |

21d27997 | 3425 | -- Spec_PPC_List (Node24) |
393e63ce RD |
3426 | -- Present in subprogram and generic subprogram entities. Points to a |
3427 | -- list of Precondition and Postcondition pragma nodes for preconditions | |
3428 | -- and postconditions declared in the spec. The last pragma encountered | |
3429 | -- is at the head of this list, so it is in reverse order of textual | |
3430 | -- appearance. | |

70482933 RK |
3432 | -- Storage_Size_Variable (Node15) [implementation base type only] |
3433 | -- Present in access types and task type entities. This flag is set | |
3434 | -- if a valid and effective pragma Storage_Size applies to the base | |
3435 | -- type. Points to the entity for a variable that is created to | |
3436 | -- hold the value given in a Storage_Size pragma for an access | |
3437 | -- collection or a task type. Note that in the access type case, | |
3438 | -- this field is present only in the root type (since derived types | |

0a36105d JM |
3441 | -- Static_Elaboration_Desired (Flag77) |
3442 | -- Present in library-level packages. Set by the pragma of the same | |
3443 | -- name, to indicate that static initialization must be attempted for | |

3445 | -- for those types to which static initialization is not available. | |
3446 | ||
3447 | -- Static_Initialization (Node26) | |
3448 | -- Present in initialization procedures for types whose objects can be | |
3449 | -- initialized statically. The value of this attribute is a positional | |
3450 | -- aggregate whose components are compile-time static values. Used | |
3451 | -- when available in object declarations to eliminate the call to the | |
3452 | -- initialization procedure, and to minimize elaboration code. | |

fbf5a39b AC |
3454 | -- Stored_Constraint (Elist23) |
3455 | -- Present in entities that can have discriminants (concurrent types | |
3456 | -- subtypes, record types and subtypes, private types and subtypes, | |
3457 | -- limited private types and subtypes and incomplete types). Points | |
3458 | -- to an element list containing the expressions for each of the | |

70482933 RK |
3461 | -- Strict_Alignment (Flag145) [implementation base type only] |
3462 | -- Present in all type entities. Indicates that some containing part | |

3466 | -- String_Literal_Length (Uint16) | |
3467 | -- Present in string literal subtypes (which are created to correspond | |

3471 | -- String_Literal_Low_Bound (Node15) | |
3472 | -- Present in string literal subtypes (which are created to correspond | |
3473 | -- to string literals in the program). Contains an expression whose | |

fdce4bb7 | 3479 | -- Present in all entities, can be set only for subprogram entities and |
6e443c90 RD |
3480 | -- for variables. If this flag is set then Sem_Elab will not generate |
3481 | -- elaboration warnings for the subprogram or variable. Suppression of | |
3482 | -- such warnings is automatic for subprograms for which elaboration | |
3483 | -- checks are suppressed (without the need to set this flag), but the | |
3484 | -- flag is also set for various internal entities (such as init procs) | |
3485 | -- which are known not to generate any possible access before | |
3486 | -- elaboration, and it is set on variables when a warning is given to | |
3487 | -- avoid multiple elaboration warnings for the same variable. | |
70482933 RK |

3489 | -- Suppress_Init_Proc (Flag105) [base type only] | |
3490 | -- Present in all type entities. Set to suppress the generation of | |

3497 | ||
0a36105d JM |
3498 | -- Suppress_Value_Tracking_On_Call (Flag217) |
3499 | -- Present in all entities. Set in a scope entity if value tracking is to | |
3500 | -- be suppressed on any call within the scope. Used when an access to a | |
3501 | -- local subprogram is computed, to deal with the possibility that this | |
3502 | -- value may be passed around, and if used, may clobber a local variable. | |

6e443c90 | 3504 | -- Task_Body_Procedure (Node25) |
a9d8907c JM |
3505 | -- Present in task types and subtypes. Points to the entity for |
3506 | -- the task body procedure (as further described in Exp_Ch9, task | |
3507 | -- bodies are expanded into procedures). A convenient function to | |

3512 | -- Treat_As_Volatile (Flag41) |
3513 | -- Present in all type entities, and also in constants, components and | |
3514 | -- variables. Set if this entity is to be treated as volatile for code | |
3515 | -- generation purposes. Always set if Is_Volatile is set, but can also | |
3516 | -- be set as a result of situations (such as address overlays) where | |
3517 | -- the front end wishes to force volatile handling to inhibit aliasing | |
3518 | -- optimization which might be legally ok, but is undesirable. Note | |
3519 | -- that the back end always tests this flag rather than Is_Volatile. | |
3520 | -- The front end tests Is_Volatile if it is concerned with legality | |
3521 | -- checks associated with declared volatile variables, but if the test | |
3522 | -- is for the purposes of suppressing optimizations, then the front | |

21d27997 RD |
3524 | -- |
3525 | -- Note: before testing Treat_As_Volatile, consider whether it would | |
3526 | -- be more appropriate to use Exp_Util.Is_Volatile_Reference instead, | |

3550 | -- attribute of the full view that is a subtype of Td with the same | |
3551 | -- constraint as the declaration for T. The declaration for this subtype | |
3552 | -- is built at the point of the declaration of T, either as completion, | |
3553 | -- or as a subtype declaration where the base type is private and has a | |
3554 | -- private completion. If Td is already constrained, then its full view | |

3663 | -- Classification of Entities -- | |
3664 | -------------------------------- | |
3665 | ||
3666 | -- The classification of program entities which follows is a refinement of | |
3667 | -- the list given in RM 3.1(1). E.g., separate entities denote subtypes of | |
3668 | -- different type classes. Ada 95 entities include class wide types, | |
3669 | -- protected types, subprogram types, generalized access types, generic | |
3670 | -- formal derived types and generic formal packages. | |
3671 | ||
3672 | -- The order chosen for these kinds allows us to classify related entities | |
3673 | -- so that they are contiguous. As a result, they do not appear in the | |
3674 | -- exact same order as their order of first appearance in the LRM (For | |
3675 | -- example, private types are listed before packages). The contiguity | |
3676 | -- allows us to define useful subtypes (see below) such as type entities, | |
3677 | -- overloaded entities, etc. | |
3678 | ||
3679 | -- Each entity (explicitly or implicitly declared) has a kind, which is | |
3680 | -- a value of the following type: | |
3681 | ||
3682 | type Entity_Kind is ( | |

3684 | E_Void, | |
3685 | -- The initial Ekind value for a newly created entity. Also used as | |
3686 | -- the Ekind for Standard_Void_Type, a type entity in Standard used | |

5469 | -- Handling of Discriminants -- | |
5470 | ------------------------------- | |
5471 | ||
5472 | -- During semantic processing, discriminants are separate entities which | |
5473 | -- reflect the semantic properties and allowed usage of discriminants in | |
5474 | -- the language. | |
5475 | ||
5476 | -- In the case of discriminants used as bounds, the references are handled | |
5477 | -- directly, since special processing is needed in any case. However, there | |
5478 | -- are two circumstances in which discriminants are referenced in a quite | |
5479 | -- general manner, like any other variables: | |
5480 | ||
5481 | -- In initialization expressions for records. Note that the expressions | |
21d27997 RD |
5482 | -- used in Priority, Storage_Size, Task_Info and Relative_Deadline |
5483 | -- pragmas are effectively in this category, since these pragmas are | |
5484 | -- converted to initialized record fields in the Corresponding_Record_ | |
5485 | -- Type. | |
70482933 RK |
5486 | |
5487 | -- In task and protected bodies, where the discriminant values may be | |
5488 | -- referenced freely within these bodies. Discriminants can also appear | |
5489 | -- in bounds of entry families and in defaults of operations. | |
5490 | ||
5491 | -- In both these cases, the discriminants must be treated essentially as | |
5492 | -- objects. The following approach is used to simplify and minimize the | |
5493 | -- special processing that is required. | |
5494 | ||
21d27997 RD |
5495 | -- When a record type with discriminants is analyzed, semantic processing |
5496 | -- creates the entities for the discriminants. It also creates additional | |
5497 | -- sets of entities called discriminals, one for each of the discriminants, | |
5498 | -- and the Discriminal field of the discriminant entity points to this | |
5499 | -- additional entity, which is initially created as an uninitialized | |
5500 | -- (E_Void) entity. | |
70482933 RK |
5501 | |
5502 | -- During expansion of expressions, any discriminant reference is replaced | |
5503 | -- by a reference to the corresponding discriminal. When the initialization | |
5504 | -- procedure for the record is created (there will always be one, since | |
5505 | -- discriminants are present, see Exp_Ch3 for further details), the | |
5506 | -- discriminals are used as the entities for the formal parameters of | |
5507 | -- this initialization procedure. The references to these discriminants | |
5508 | -- have already been replaced by references to these discriminals, which | |
5509 | -- are now the formal parameters corresponding to the required objects. | |
5510 | ||
21d27997 RD |
5511 | -- In the case of a task or protected body, the semantics similarly creates |
5512 | -- a set of discriminals for the discriminants of the task or protected | |
5513 | -- type. When the procedure is created for the task body, the parameter | |
5514 | -- passed in is a reference to the task value type, which contains the | |
5515 | -- required discriminant values. The expander creates a set of declarations | |
5516 | -- of the form: | |
70482933 | 5517 | |
f3d0f304 | 5518 | -- discr_nameD : constant discr_type renames _task.discr_name; |
70482933 | 5519 | |
21d27997 RD |
5520 | -- where discr_nameD is the discriminal entity referenced by the task |
5521 | -- discriminant, and _task is the task value passed in as the parameter. | |
70482933 RK |
5522 | -- Again, any references to discriminants in the task body have been |
5523 | -- replaced by the discriminal reference, which is now an object that | |
5524 | -- contains the required value. | |
5525 | ||
5526 | -- This approach for tasks means that two sets of discriminals are needed | |
5527 | -- for a task type, one for the initialization procedure, and one for the | |
5528 | -- task body. This works out nicely, since the semantics allocates one set | |
5529 | -- for the task itself, and one set for the corresponding record. | |
5530 | ||
5531 | -- The one bit of trickiness arises in making sure that the right set of | |
5532 | -- discriminals is used at the right time. First the task definition is | |
5533 | -- processed. Any references to discriminants here are replaced by the | |
21d27997 RD |
5534 | -- corresponding *task* discriminals (the record type doesn't even exist |
5535 | -- yet, since it is constructed as part of the expansion of the task | |
5536 | -- declaration, which happens after the semantic processing of the task | |
5537 | -- definition). The discriminants to be used for the corresponding record | |
5538 | -- are created at the same time as the other discriminals, and held in the | |
5539 | -- CR_Discriminant field of the discriminant. A use of the discriminant in | |
5540 | -- a bound for an entry family is replaced with the CR_Discriminant because | |
5541 | -- it controls the bound of the entry queue array which is a component of | |
5542 | -- the corresponding record. | |
70482933 RK |
5543 | |
5544 | -- Just before the record initialization routine is constructed, the | |
5545 | -- expander exchanges the task and record discriminals. This has two | |
5546 | -- effects. First the generation of the record initialization routine | |
5547 | -- uses the discriminals that are now on the record, which is the set | |
5548 | -- that used to be on the task, which is what we want. | |
5549 | ||
5550 | -- Second, a new set of (so far unused) discriminals is now on the task | |
5551 | -- discriminants, and it is this set that will be used for expanding the | |
5552 | -- task body, and also for the discriminal declarations at the start of | |
5553 | -- the task body. | |

5556 | -- Handling of private data in protected objects -- | |
5557 | --------------------------------------------------- | |
5558 | ||
5559 | -- Private components in protected types pose problems similar to those | |
5560 | -- of discriminants. Private data is visible and can be directly referenced | |

5563 | -- components lose their original context and visibility. | |
5564 | ||
5565 | -- To remedy this side effect of expansion, private components are expanded | |
5566 | -- into renamings called "privals", by analogy with "discriminals". | |

5572 | -- _Object is the formal parameter of the generated corresponding body or | |
5573 | -- a local renaming which denotes the protected object obtained from entry | |
5574 | -- parameter _O. Privals receive minimal decoration upon creation and are | |
5575 | -- categorized as either E_Variable for the general case or E_Constant when | |
5576 | -- they appear in functions. | |
5577 | ||
5578 | -- Along with the local declarations, each private component carries a | |
5579 | -- placeholder which references the prival entity in the current body. This | |
5580 | -- form of indirection is used to resolve name clashes of privals and other | |
5581 | -- locally visible entities such as parameters, local objects, entry family | |
5582 | -- indexes or identifiers used in the barrier condition. | |
5583 | ||
5584 | -- When analyzing the statements of a protected subprogram or entry, any | |
5585 | -- reference to a private component must resolve to the locally declared | |
5586 | -- prival through normal visibility. In case of name conflicts (the cases | |
5587 | -- above), the prival is marked as hidden and acts as a weakly declared | |
5588 | -- entity. As a result, the reference points to the correct entity. When a | |
5589 | -- private component is denoted by an expanded name (prot_type.comp for | |
5590 | -- example), the expansion mechanism uses the placeholder of the component | |
5591 | -- to correct the Entity and Etype of the reference. | |
