72
73 2018-05-29 Arnaud Charlet <charlet@adacore.com>
74
75 * lib-writ.adb (Write_ALI): Do not use new function from s-casuti yet.
76 This breaks build of cross compilers with older versions of GNAT, so
77 better avoid it.
78
79 2018-05-29 Doug Rupp <rupp@adacore.com>
80
81 * libgnarl/s-taprop.ads (Monotonic_Clock): Refine documentation to

93 and formatting conventions.
94
95 2018-05-29 Bob Duff <duff@adacore.com>
96
97 * lib-writ.adb (Write_ALI): Cleanup: avoid use of global var; call new

100 To_Mixed): New functions.
101 * osint.adb: Cleanup: use Is_Directory_Separator, which correctly

105
106 * repinfo.ads: Minor fixes and tweaks in comments.

127
128 2018-05-28 Ed Schonberg <schonberg@adacore.com>
129
130 * exp_unst.adb (Visit_Node): For indexed components and attribute
131 references, examine index expressions or associated expressions as well
132 to record uplevel references.
133 (Vist_Node): For function and procedure calls, if a formal is an
134 unconstrained array and the actual is constrained, check whether bounds
135 of actual have uplevel references.
136
137 2018-05-28 Ed Schonberg <schonberg@adacore.com>
138
139 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
140 they can appear as components of activation records.
141 * exp_unst.adb (Visit_Node): A reference to an exception may be an
142 uplevel reference.
143
144 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
145
146 * exp_ch4.adb (Expand_Composite_Equality): Compute whether the size
147 depends on a discriminant manually instead of using the predicate
148 Size_Depends_On_Discriminant in the array type case.
149
150 2018-05-28 Ed Schonberg <schonberg@adacore.com>
151
152 * exp_unst.adb (Check_Static_Type): For a record subtype, check
153 discriminant constraints as well.

158
159 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
160 value when converting a float value to a fixed-point value. This is
161 required for CCG because it handles fixed-point types by means of
162 unsigned integer type variables. The range check is now performed using
163 the integer value stored in this temporary.
164
165 2018-05-28 Yannick Moy <moy@adacore.com>
166
167 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and

177 Is_Overriding_Subprogram, generic in Find_Dispatching_Type function.
178 (Inherited_Subprograms): Instance of Generic_Inherited_Subprograms with
179 Sem_Disp.Find_Dispatching_Type.
180 (Is_Overriding_Subprogram): Instance of
181 Generic_Is_Overriding_Subprogram with Sem_Disp.Find_Dispatching_Type.
182 (Inheritance_Utilities_Inst): Instance of Inheritance_Utilities
183 with Sem_Disp.Find_Dispatching_Type.
184
185 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
186
187 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
188 component type, do not expand array equality using the unconstrained
189 base type, except for the case where the bounds of the type depend on a
190 discriminant.
191
192 2018-05-28 Ed Schonberg <schonberg@adacore.com>
193
194 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
195 access-to-subprogram types, to indicate that an indirect call through
196 such a type requires an activation record when compiling for LLVM.
197 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
198
199 2018-05-28 Ed Schonberg <schonberg@adacore.com>
200
201 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
202 when bounds of fixed type are static, to remove some spuerfluous
203 implicit conversions and provide an accurate result when converting
204 back and forth between the fixed point type and a floating point type.
205
206 2018-05-28 Ed Schonberg <schonberg@adacore.com>
207
208 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
209 activation records.
210
211 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
212
213 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
214 replaced, if any; all callers changed.
215 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
216 constant with private view so we take the address of that entity.
217 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
218 any; all callers changed. Handle N_Indexed_Component like
219 N_Attribute_Reference. Add N_Type_Conversion case.
220 (Visit_Node): Indexed references can be uplevel if the type isn't
221 static.
222 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
223 been relocated, set first_named pointer in original node as well.
224
225 2018-05-28 Ed Schonberg <schonberg@adacore.com>
226
227 * exp_aggr.adb (Flatten): Copy tree of expression in a component
228 association with a range or a set of discrete choices, rather than
229 relocating the node. This avoids inconsistencies in the tree when
230 handling nested subprograms with uplevel references for LLVM.
231
232 2018-05-28 Arnaud Charlet <charlet@adacore.com>
233
234 * exp_util.adb (Possible_Bit_Aligned_Component): Always return False in
235 codepeer mode.
236
237 2018-05-28 Arnaud Charlet <charlet@adacore.com>
238
239 * exp_unst.adb: Fix typo.
240
241 2018-05-28 Bob Duff <duff@adacore.com>
242
243 * libgnat/a-convec.adb (Query_Element): Minor cleanup: remove an
244 unnecessary use of 'Unrestricted_Access.
245
246 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
247
248 * repinfo.adb (Expr_Value_S): New routine.

250 argument.
251
252 2018-05-28 Patrick Bernardi <bernardi@adacore.com>

255 description of the -D binder switch to reflect current usage.
256 * gnat_ugn.texi: Regenerate.
257
258 2018-05-28 Gary Dismukes <dismukes@adacore.com>
259
260 * exp_ch3.adb: Minor reformatting
261
262 2018-05-28 Justin Squirek <squirek@adacore.com>
263
264 * exp_ch3.adb
265 (Build_Initialization_Call): Add logic to pass the appropriate actual to match
266 new formal.
267 (Init_Formals): Add new formal *_skip_null_excluding_check
268 * exp_util.adb, exp_util.ads
269 (Enclosing_Init_Proc): Added to fetch the enclosing Init_Proc from the current
270 scope.
271 (Inside_Init_Proc): Refactored to use Enclosing_Init_Proc
272 (Needs_Conditional_Null_Excluding_Check): Added to factorize the predicate
273 used to determine how to generate an Init_Proc for a given type.
274 (Needs_Constant_Address): Minor reformatting
275 * sem_res.adb
276 (Resolve_Null): Add logic to generate a conditional check in certain cases
277
278 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
279
280 * exp_aggr.adb, gnatlink.adb, sem_ch6.adb, sem_res.adb, sem_util.adb:
281 Minor reformatting.
282
283 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
284
285 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
286 the declarations of single concurrent types because they fall in the
287 category of full type and object declarations.
288
289 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
290
291 * repinfo.adb (Compute_Max_Length): Skip _Parent component.
292 (List_Record_Layout): Likewise.
293
294 2018-05-28 Ed Schonberg <schonberg@adacore.com>
295
296 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
297 includes a call to function to which it applies. This may mean an
298 omission of an attribute reference 'Result, in particular if the
299 function is pqrameterless.
300
301 2018-05-28 Justin Squirek <squirek@adacore.com>
302
303 * sem_ch8.adb (Find_Expanded_Name): Add extra guard to make sure the
304 misresolved package name is not a case of mistaken identity.
305
306 2018-05-28 Yannick Moy <moy@adacore.com>
307
308 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
309 GNATprove mode, as the order of resolution (low then high) means that
310 all the information is not available when resolving the low bound the
311 first time.
312
313 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
314
315 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
316 end with the linker section, if any.
317 (List_Entities): Do not output the linker section for record types,
318 array types and variables.
319 (Print_Expr): Factor out common processing for unary operators and
320 special values. Adjust and reorder the various cases.
321 (List_Object_Info): End with the linker section, if any.
322 (List_Record_Info): Likewise.
323 (List_Type_Info): Do not start with a blank line.
324
325 2018-05-25 Nicolas Roche <roche@adacore.com>
326
327 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
328 that the result will be either -infinite or +infinite.
329
330 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
331
332 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,
333 libgnat/s-parame__ae653.ads, libgnat/s-parame__hpux.ads (Size_Type):
334 Expand range of type to match the address space of the target.
335 (Task_Storage_Size): Remove unused type.
336
337 2018-05-25 Ed Schonberg <schonberg@adacore.com>
338
339 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
340 of a fixed point type and the parent is a multiplying operation,
341 resolve the operand with its own type because the context will impose a
342 resulting type on the result of the multiplication by means of
343 approriate conversion.
344
345 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
346
347 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
348 the in-place initialization aggregate created for pragmas
349 Initialize_Scalars or Normalize_Scalars is performed with checks
350 suppressed.
351
352 2018-05-25 Arnaud Charlet <charlet@adacore.com>
353
354 * exp_aggr.adb (Convert_To_Positional): Bump default for
355 Max_Others_Replicate to 32. Update comments.
356 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
357 (No_File_Info_Cache): Initialize separately.
358 * osint.adb (No_File_Info_Cache): Update initializer.
359
360 2018-05-25 Javier Miranda <miranda@adacore.com>
361
362 * sem_res.adb (Resolve_Membership_Op): Allow the use of the membership
363 test when the left operand is a class-wide interface and the right
364 operand is not a class-wide type.
365 * exp_ch4.adb (Tagged_Membership): Adding support for interface as the
366 left operand.
367
368 2018-05-25 Ed Schonberg <schonberg@adacore.com>
369
370 * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated
371 in an others clause to prevent visibility issues with the generated
372 loop variable.
373 (Component_OK_For_Backend): Return false for a quantified expression.
374 (Check_Static_Component): Ditto.
375
376 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
377
378 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
379 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
380 into three distring cases rather than in one loop which attempts to
381 handle all three cases. This rewrite eliminates an issue where the last
382 frame of the stack cannot be freed, thus causing the memory range of a
383 new frame to approach the overflow point of the memory index type.
384 Since the overflow is logically treated as a
385 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
386 (SS_Allocate_Static): New routine. The routine factorizes the static
387 secondary stack-related code from the former SS_Allocate.
388
389 2018-05-25 Sergey Rybin <rybin@adacore.com>
390
391 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
392 option for gnatelim.
393
394 2018-05-25 Ed Schonberg <schonberg@adacore.com>
395
396 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
397 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
398 is created when the proper body of the stub is analyzed.
399 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
400 is the proper body of a subunit, the cloned body must be inserted in
401 the declarative list that contains the stub.
402
403 2018-05-25 Justin Squirek <squirek@adacore.com>
404
405 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
406 generate code for 6.5(8-10) so that we don't get an assertion error
407 when dealing with an incomplete return type.
408
409 2018-05-25 Arnaud Charlet <charlet@adacore.com>
410
411 * pprint.adb (Expression_Name): Strip too long expressions to avoid
412 carrying very large strings.
413
414 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
415
416 * switch-b.adb (Scan_Binder_Switches): binder switch -Q accepts Natural
417 numbers.
418
419 2018-05-25 Doug Rupp <rupp@adacore.com>
420
421 * tracebak.c (aarch64-linux): Implement.
422
423 2018-05-25 Justin Squirek <squirek@adacore.com>
424
425 * sem_ch8.adb: Minor reformatting.
426
427 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
428
429 * sem_util.adb (Iterate_Call_Parameters): Fix code convention and
430 assertions.
431
432 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
433
434 * einfo.adb, einfo.ads, exp_ch3.adb, exp_ch8.adb, exp_unst.adb,
435 pprint.adb, sem_ch12.adb, sem_ch3.adb, sem_prag.adb, sem_util.adb:
436 Minor reformatting.
437
438 2018-05-25 Ed Schonberg <schonberg@adacore.com>
439
440 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
441 Validate_Derived_Type_Instance, to verify that all interfaces
442 implemented by the formal type are also implemented by the actual. The
443 verification is complicated when an interface of the formal is declared
444 in a generic unit and the actual is declared in an instance of it.
445 There is currently no mechanism to relate an interface declared within
446 a generic to the corresponding interface in an instance, so we must
447 traverse the list of interfaces of the actual, looking for a name
448 match, and verifying that that interface is declared in an instance.
449
450 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
451
452 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
453 assertions; replace function versions of Next_Formal/Next_Actual with
454 their procedural versions (which are more concise).
455
456 2018-05-25 Doug Rupp <rupp@adacore.com>
457
458 * libgnarl/s-osinte__aix.ads, libgnarl/s-osinte__android.ads,
459 libgnarl/s-osinte__darwin.ads, libgnarl/s-osinte__freebsd.ads,
460 libgnarl/s-osinte__hpux.ads, libgnarl/s-osinte__kfreebsd-gnu.ads,
461 libgnarl/s-osinte__linux.ads, libgnarl/s-osinte__lynxos178e.ads,
462 libgnarl/s-osinte__qnx.ads, libgnarl/s-osinte__rtems.ads
463 (Relative_Timed_Wait): Remove.
464 * libgnarl/s-tpopmo.adb (Timed_Sleep, Timed_Delay): Rewrite to allow
465 for incremental looping. Remove references to Rel_Time and
466 Relative_Timed_Wait.
467 * libgnat/s-osprim__posix.adb, libgnat/s-osprim__posix2008.adb
468 (Timed_Delay): Make separate.

1691 the comment on usage.
1692 (Find_Transient_Context): Change the initinte loop into a while loop.

1824 properly object declarations with initializations that are
1825 build-in-place function calls, when there is an address specification,
1826 either as an aspect specification or an explicit attribute
1827 specification clause, for the initialized object.
1828 * freeze.adb (Check_Address_Clause): Do not remove side-effects from
1829 initial expressions in the case of a build-in-place call.
1830

1854 as Part_Of consituents of single protected types are illegal when they
1855 take place inside a protected function.
1856 (Diagnose_Non_Variable_Lhs): Use Within_Function to check for an
1857 enclosing function.
1858 (Is_Protected_Part_Of_Constituent): New routine.

1872 * par-ch6.adb (Scan_Body_Or_Expression_Function): Add additional check
1873 to make sure a given expression function is properly parenthesized.
1874
1875 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
1876
1877 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Check the
1878 categorization of a subprogram body which does not complete a previous
1879 declaration.

1889 subcomponent of the current entity when building the body for a dynamic
1890 predicate function for a record with composite subcomponents.
1891

1900 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
1901 Establish_Transient_Scope.
1902 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
1903 management of the secondary stack to an enclosing scope if there is no
1904 suitable construct to wrap, and the transient scope was intended to
1905 manage the secondary stack.
1906 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
1907 is a valid boundary for a transient expression which comes from the
1908 statements of the alternative, otherwise alternatives cannot be
1909 wrapped. Assignments of controlled objects which have controlled
1910 actions suppressed now stop the traversal as there is no point in
1911 looking for an enclosing construct. Add several N_xxx_Body choices to
1912 the termination conditions for completeness.
1913 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
1914 and the associated comment on usage.
1915 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
1916 Establish_Transient_Scope.
1917 (Add_Write_After): Update the call to Establish_Transient_Scope.

1919 (Resolve_Actuals): Account for additional cases where finalization
1920 actions are required by utilizing predicate Needs_Finalization rather
1921 than Is_Controlled.
1922 (Resolve_Call): Type initialization procedures can now utilize
1923 transient scopes to manage the secondary stack, thus preventing leaks
1924 during initialization. Remove the previous kludgy algorithm which
1925 attempts to manage the secondary stack at the object creation site.
1926

1968 2018-01-11 Ed Schonberg <schonberg@adacore.com>
1969
1970 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
1971 formsl type corresponding to the actual fixed point type is private,
1972 because in this case there can be no suspicious arithmetic operations
1973 in the generic unless they reference a formal subprogram. Clarify
1974 warning.
1975
1976 2018-01-11 Javier Miranda <miranda@adacore.com>
1977
1978 * exp_util.adb (Remove_Side_Effects): No action done for functions
1979 returning class-wide types since it requires generating code using
1980 'reference and the CCG target has no secondary stack.
1981 * gnat1drv.adb: Disable building static dispatch tables when generating
1982 C code.
1983
1984 2018-01-11 Piotr Trojanek <trojanek@adacore.com>

2003 if it contains at least one component declaration employing a function
2004 call returning on the secondary stack.
2005
2006 2018-01-11 Yannick Moy <moy@adacore.com>

2022
2023 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
2024 has a delayed aspect which must be processed at the point the type is
2025 frozen. This mimics what is done when the predicate is provided by a
2026 source aspect.

2040 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
2041 Default_Sec_Stack_Size.
2042 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
2043 limit check so that the integer index does not overflow. Check the
2044 dynamic stack allocation does not cause the secondary stack pointer to
2045 overflow.
2046 (SS_Info): Align colons.
2047 (SS_Init): Cover the case when bootstraping with an old compiler that
2048 does not set Default_SS_Size.

2050 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2051
2052 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the

2055 an interface primitive.
2056 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
2057 operation to which the class-wide expression applies is a protected op.
2058 with a primitive_wrapper, verify that the updated inherited expression
2059 does not contain an internal call to a protected function. This
2060 completes the implementation of AI12-0166.
2061
2062 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2063
2064 * ali.adb: Document the remaining letters available for ALI lines.
2065 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
2066 * ali.ads: Update type With_Record. Field
2067 Implicit_With_From_Instantiation is no longer in use. Add field
2068 Implicit_With.
2069 * csinfo.adb (CSinfo): Remove the setup for attribute
2070 Implicit_With_From_Instantiation.
2071 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
2072 either implicitly or explicitly withed.
2073 (Is_Implicit_With_Clause): New routine.
2074 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2075 confusion with the with clause attribute by the same name.
2076 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
2077 * rtsfind.adb (Maybe_Add_With): Code cleanup.

2085 because they are already marked as implicit.
2086 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
2087 which marks implicit with clauses as related to an instantiation.
2088 * sinfo.adb (Implicit_With_From_Instantiation): Removed.

2107
2108 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2109 Secondary_Stack_Size handling as a pragma is now generated for the
2110 corresponding aspect instead of an attribute. Pragma expression is
2111 relocated instead of evaluated. Discriminant of the corresponding
2112 record type is referenced rather than the type discriminant.
2113 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2114 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2115 * sem_ch13.adb (Analyze_One_Aspect): Transform
2116 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2117 because the attribute does not have visibility on a task type's
2118 discriminants when the type's definition is expanded.
2119 (Analyze_Attribute_Definition_Clause): Remove handling of
2120 Attribute_Secondary_Stack_Size.
2121 * snames.adb-tmpl, snames.ads-tmpl: Remove
2122 Attribute_Secondary_Stack_Size, no longer used.

2127
2128 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2129
2130 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
2131 individual action because the action may denote a complex expression,
2132 such as a case statement, which in turn may contain additional
2133 transient objects.
2134
2135 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2136
2137 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2138 analysis on a copy of the expression with a copy of the index variable,
2139 because full expansion will rewrite construct into a loop with the
2140 original loop variable.
2141 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2142 expression is an iterated component association. Full analysis takes
2143 place when construct is rewritten as a loop.
2144 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2145 is not safe for in-place assignment.
2146 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
2147 entity with no homonym and no other entity in the scope.
