10 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
12 * repinfo.ads (TCode): Adjust range.
13 (Truth_Andif_Expr): Remove.
14 (Truth_Orif_Expr): Likewise.
15 (Truth_And_Expr .. Dynamic_Val): Adjust value.
16 * repinfo.adb (Print_Expr): Remove handling of Truth_{And,Or}if_Expr.
17 (Rep_Value): Likewise.

22 through to TRUTH_AND_EXPR case.
23 <TRUTH_ORIF_EXPR>: Fall through to TRUTH_OR_EXPR case.
25 2018-05-28 Ed Schonberg <schonberg@adacore.com>
27 * exp_unst.adb (Visit_Node): For indexed components and attribute
28 references, examine index expressions or associated expressions as well
29 to record uplevel references.
30 (Vist_Node): For function and procedure calls, if a formal is an
31 unconstrained array and the actual is constrained, check whether bounds
32 of actual have uplevel references.
34 2018-05-28 Ed Schonberg <schonberg@adacore.com>
36 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
37 they can appear as components of activation records.
38 * exp_unst.adb (Visit_Node): A reference to an exception may be an
41 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
43 * exp_ch4.adb (Expand_Composite_Equality): Compute whether the size
44 depends on a discriminant manually instead of using the predicate
45 Size_Depends_On_Discriminant in the array type case.
47 2018-05-28 Ed Schonberg <schonberg@adacore.com>
49 * exp_unst.adb (Check_Static_Type): For a record subtype, check
50 discriminant constraints as well.

52 done for indexed components and slices.
54 2018-05-28 Javier Miranda <miranda@adacore.com>
56 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
57 value when converting a float value to a fixed-point value. This is
58 required for CCG because it handles fixed-point types by means of
59 unsigned integer type variables. The range check is now performed using
60 the integer value stored in this temporary.
62 2018-05-28 Yannick Moy <moy@adacore.com>
64 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and
65 Length as valid non-interfering contexts for SPARK.
67 2018-05-28 Claire Dross <dross@adacore.com>
69 * sem_disp.ads, sem_disp.adb (Inheritance_Utilities): Package for
70 generic inheritance utilities.
71 (Generic_Inherited_Subprograms): Generic version of
72 Inherited_Subprograms, generic in Find_Dispatching_Type function.
73 (Generic_Is_Overriding_Subprogram): Generic version of
74 Is_Overriding_Subprogram, generic in Find_Dispatching_Type function.
75 (Inherited_Subprograms): Instance of Generic_Inherited_Subprograms with
76 Sem_Disp.Find_Dispatching_Type.
77 (Is_Overriding_Subprogram): Instance of
78 Generic_Is_Overriding_Subprogram with Sem_Disp.Find_Dispatching_Type.
79 (Inheritance_Utilities_Inst): Instance of Inheritance_Utilities
80 with Sem_Disp.Find_Dispatching_Type.
82 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
84 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
85 component type, do not expand array equality using the unconstrained
86 base type, except for the case where the bounds of the type depend on a
89 2018-05-28 Ed Schonberg <schonberg@adacore.com>
91 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
92 access-to-subprogram types, to indicate that an indirect call through
93 such a type requires an activation record when compiling for LLVM.
94 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
96 2018-05-28 Ed Schonberg <schonberg@adacore.com>
98 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
99 when bounds of fixed type are static, to remove some spuerfluous
100 implicit conversions and provide an accurate result when converting
101 back and forth between the fixed point type and a floating point type.
103 2018-05-28 Ed Schonberg <schonberg@adacore.com>
105 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
108 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
110 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
111 replaced, if any; all callers changed.
112 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
113 constant with private view so we take the address of that entity.
114 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
115 any; all callers changed. Handle N_Indexed_Component like
116 N_Attribute_Reference. Add N_Type_Conversion case.
117 (Visit_Node): Indexed references can be uplevel if the type isn't
119 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
120 been relocated, set first_named pointer in original node as well.
122 2018-05-28 Ed Schonberg <schonberg@adacore.com>
124 * exp_aggr.adb (Flatten): Copy tree of expression in a component
125 association with a range or a set of discrete choices, rather than
126 relocating the node. This avoids inconsistencies in the tree when
127 handling nested subprograms with uplevel references for LLVM.
129 2018-05-28 Arnaud Charlet <charlet@adacore.com>
131 * exp_util.adb (Possible_Bit_Aligned_Component): Always return False in
134 2018-05-28 Arnaud Charlet <charlet@adacore.com>
136 * exp_unst.adb: Fix typo.
138 2018-05-28 Bob Duff <duff@adacore.com>
140 * libgnat/a-convec.adb (Query_Element): Minor cleanup: remove an
141 unnecessary use of 'Unrestricted_Access.
143 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
145 * repinfo.adb (Expr_Value_S): New routine.
146 (List_Linker_Section): Properly extract the value of the section
149 2018-05-28 Patrick Bernardi <bernardi@adacore.com>
151 * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Update the
152 description of the -D binder switch to reflect current usage.
153 * gnat_ugn.texi: Regenerate.
155 2018-05-28 Gary Dismukes <dismukes@adacore.com>

168 (Inside_Init_Proc): Refactored to use Enclosing_Init_Proc
169 (Needs_Conditional_Null_Excluding_Check): Added to factorize the predicate
170 used to determine how to generate an Init_Proc for a given type.
171 (Needs_Constant_Address): Minor reformatting
173 (Resolve_Null): Add logic to generate a conditional check in certain cases
175 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
177 * exp_aggr.adb, gnatlink.adb, sem_ch6.adb, sem_res.adb, sem_util.adb:
180 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
182 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
183 the declarations of single concurrent types because they fall in the
184 category of full type and object declarations.
186 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
188 * repinfo.adb (Compute_Max_Length): Skip _Parent component.
189 (List_Record_Layout): Likewise.
191 2018-05-28 Ed Schonberg <schonberg@adacore.com>
193 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
194 includes a call to function to which it applies. This may mean an
195 omission of an attribute reference 'Result, in particular if the
196 function is pqrameterless.
198 2018-05-28 Justin Squirek <squirek@adacore.com>
200 * sem_ch8.adb (Find_Expanded_Name): Add extra guard to make sure the
201 misresolved package name is not a case of mistaken identity.
203 2018-05-28 Yannick Moy <moy@adacore.com>
205 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
206 GNATprove mode, as the order of resolution (low then high) means that
207 all the information is not available when resolving the low bound the
210 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
212 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
213 end with the linker section, if any.
214 (List_Entities): Do not output the linker section for record types,
215 array types and variables.
216 (Print_Expr): Factor out common processing for unary operators and
217 special values. Adjust and reorder the various cases.
218 (List_Object_Info): End with the linker section, if any.
219 (List_Record_Info): Likewise.
220 (List_Type_Info): Do not start with a blank line.
222 2018-05-25 Nicolas Roche <roche@adacore.com>
224 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
225 that the result will be either -infinite or +infinite.
227 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
229 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,
230 libgnat/s-parame__ae653.ads, libgnat/s-parame__hpux.ads (Size_Type):
231 Expand range of type to match the address space of the target.
232 (Task_Storage_Size): Remove unused type.
234 2018-05-25 Ed Schonberg <schonberg@adacore.com>
236 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
237 of a fixed point type and the parent is a multiplying operation,
238 resolve the operand with its own type because the context will impose a
239 resulting type on the result of the multiplication by means of
240 approriate conversion.
242 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
244 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
245 the in-place initialization aggregate created for pragmas
246 Initialize_Scalars or Normalize_Scalars is performed with checks
249 2018-05-25 Arnaud Charlet <charlet@adacore.com>
251 * exp_aggr.adb (Convert_To_Positional): Bump default for
252 Max_Others_Replicate to 32. Update comments.
253 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
254 (No_File_Info_Cache): Initialize separately.
255 * osint.adb (No_File_Info_Cache): Update initializer.
257 2018-05-25 Javier Miranda <miranda@adacore.com>
259 * sem_res.adb (Resolve_Membership_Op): Allow the use of the membership
260 test when the left operand is a class-wide interface and the right
261 operand is not a class-wide type.
262 * exp_ch4.adb (Tagged_Membership): Adding support for interface as the
265 2018-05-25 Ed Schonberg <schonberg@adacore.com>
267 * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated
268 in an others clause to prevent visibility issues with the generated
270 (Component_OK_For_Backend): Return false for a quantified expression.
271 (Check_Static_Component): Ditto.
273 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
275 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
276 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
277 into three distring cases rather than in one loop which attempts to
278 handle all three cases. This rewrite eliminates an issue where the last
279 frame of the stack cannot be freed, thus causing the memory range of a
280 new frame to approach the overflow point of the memory index type.
281 Since the overflow is logically treated as a
282 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
283 (SS_Allocate_Static): New routine. The routine factorizes the static
284 secondary stack-related code from the former SS_Allocate.
286 2018-05-25 Sergey Rybin <rybin@adacore.com>
288 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
291 2018-05-25 Ed Schonberg <schonberg@adacore.com>
293 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
294 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
295 is created when the proper body of the stub is analyzed.
296 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
297 is the proper body of a subunit, the cloned body must be inserted in
298 the declarative list that contains the stub.
300 2018-05-25 Justin Squirek <squirek@adacore.com>
302 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
303 generate code for 6.5(8-10) so that we don't get an assertion error
304 when dealing with an incomplete return type.
306 2018-05-25 Arnaud Charlet <charlet@adacore.com>
308 * pprint.adb (Expression_Name): Strip too long expressions to avoid
309 carrying very large strings.
311 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
313 * switch-b.adb (Scan_Binder_Switches): binder switch -Q accepts Natural
316 2018-05-25 Doug Rupp <rupp@adacore.com>
318 * tracebak.c (aarch64-linux): Implement.
320 2018-05-25 Justin Squirek <squirek@adacore.com>
322 * sem_ch8.adb: Minor reformatting.
324 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
326 * sem_util.adb (Iterate_Call_Parameters): Fix code convention and

335 2018-05-25 Ed Schonberg <schonberg@adacore.com>
337 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
338 Validate_Derived_Type_Instance, to verify that all interfaces
339 implemented by the formal type are also implemented by the actual. The
340 verification is complicated when an interface of the formal is declared
341 in a generic unit and the actual is declared in an instance of it.
342 There is currently no mechanism to relate an interface declared within
343 a generic to the corresponding interface in an instance, so we must
344 traverse the list of interfaces of the actual, looking for a name
345 match, and verifying that that interface is declared in an instance.
347 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
349 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
350 assertions; replace function versions of Next_Formal/Next_Actual with
351 their procedural versions (which are more concise).
353 2018-05-25 Doug Rupp <rupp@adacore.com>

360 (Relative_Timed_Wait): Remove.
361 * libgnarl/s-tpopmo.adb (Timed_Sleep, Timed_Delay): Rewrite to allow
362 for incremental looping. Remove references to Rel_Time and
364 * libgnat/s-osprim__posix.adb, libgnat/s-osprim__posix2008.adb
365 (Timed_Delay): Make separate.
366 * libgnat/s-optide.adb: New separate procedure.
367 * libgnat/s-osprim.ads (Max_System_Delay): New constant.
368 * libgnat/s-osprim__lynxos.ads (Max_Sensible_Delay): Set to 6 months.
369 (Max_System_Delay): New constant.

388 FOREIGN and use it throughout the function.
389 <E_Enumeration_Type>: Set precision 1 on boolean types with foreign
391 <E_Enumeration_Subtype>: Likewise for subtypes.
392 <E_Record_Type>: Force the size of a storage unit on empty classes.
393 * gcc-interface/utils.c (make_type_from_size) <BOOLEAN_TYPE>: Skip
394 boolean types with precision 1 if the size is the expected one.
396 2018-05-25 Arnaud Charlet <charlet@adacore.com>
398 * pprint.adb (Expression_Name): Do not print non ASCII characters.
400 2018-05-25 Bob Duff <duff@adacore.com>
402 * libgnat/a-strunb__shared.ads, libgnat/a-stwiun__shared.ads,

412 prefixes of array attributes, to prefixes that are entity names whose
414 (Note_Uplevel_Bound): Verify that the bound is declared in an enclosing
415 subprogram, as itype created for loops in pre/postcondition may appear
416 in loops at the library level.
418 2018-05-25 Ed Schonberg <schonberg@adacore.com>
420 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
421 declaration is inserted into the tree and analyzed at that point, so
422 should not be reinserted when the body is constructed. Inside a
423 generic, ensure that the body is not inserted twice in the tree.
425 2018-05-25 Yannick Moy <moy@adacore.com>
427 * sem_prag.adb (Check_Grouping): Modify test to ignore statements and
428 declarations not coming from source.

456 <N_Raise_Statement>: Likewise.
458 2018-05-24 Javier Miranda <miranda@adacore.com>
460 * exp_ch8.adb (Build_Body_For_Renaming): Adding support to build the
461 body of a variant record equality renaming.
462 (Expand_N_Subprogram_Renaming_Declaration): Adapt the code to the new
463 implementation of Build_Body_For_Renaming.
464 * exp_ch3.ads (Build_Variant_Record_Equality): New library level
465 function that factorizes the functionality needed by
466 Build_Body_For_Renaming and Expand_Freeze_Record_Type to build the body
467 of a variant record equality subprogram.
468 * exp_ch3.adb (Build_Variant_Record_Equality): New subprogram.

1532 (Multi_Module_Symbolic_Traceback): Compare address in traceback
1533 with module Low_Address instead of Low.

1548 lm.l_addr as the Load_Address to Add_Module_To_Cache.

1581 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
1582 delegate the secondary stack management when there is no suitable
1583 transient context, and the transient scope was intended to manage the
1584 secondary stack because this causes premature reclamation. Change the
1585 transient scope creation logic by special casing assignment statements
1586 of controlled components for type initialization procedures.
1587 (Find_Node_To_Be_Wrapped): Renamed to Find_Transient_Context. Update
1588 the comment on usage.
1589 (Find_Transient_Context): Change the initinte loop into a while loop.
1590 Iterations schemes and iterator specifications are not valid transient
1591 contexts because they rely on special processing. Assignment statements
1592 are now treated as a normal transient context, special cases are
1593 handled by the caller. Add special processing for pragma Check.
1594 (Is_OK_Construct): Removed. Its functionality has been merged in
1595 routine Find_Transient_Context.
1596 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly
1597 retrieve the subprogram being invoked. Use a more accurate predicate
1598 (Requires_Transient_Scope) to determine that the function will emply
1599 the secondary stack.

1803 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
1804 is a valid boundary for a transient expression which comes from the
1805 statements of the alternative, otherwise alternatives cannot be
1806 wrapped. Assignments of controlled objects which have controlled
1807 actions suppressed now stop the traversal as there is no point in
1808 looking for an enclosing construct. Add several N_xxx_Body choices to

1816 (Resolve_Actuals): Account for additional cases where finalization
1817 actions are required by utilizing predicate Needs_Finalization rather
1819 (Resolve_Call): Type initialization procedures can now utilize
1820 transient scopes to manage the secondary stack, thus preventing leaks
1821 during initialization. Remove the previous kludgy algorithm which
1822 attempts to manage the secondary stack at the object creation site.

2005 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2006 Secondary_Stack_Size handling as a pragma is now generated for the
2007 corresponding aspect instead of an attribute. Pragma expression is
2008 relocated instead of evaluated. Discriminant of the corresponding
