105 references, examine index expressions or associated expressions as well
106 to record uplevel references.

108 unconstrained array and the actual is constrained, check whether bounds
109 of actual have uplevel references.
111 2018-05-28 Ed Schonberg <schonberg@adacore.com>
113 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
114 they can appear as components of activation records.

133 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
134 value when converting a float value to a fixed-point value. This is
135 required for CCG because it handles fixed-point types by means of
136 unsigned integer type variables. The range check is now performed using
137 the integer value stored in this temporary.
139 2018-05-28 Yannick Moy <moy@adacore.com>
141 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and

168 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
169 access-to-subprogram types, to indicate that an indirect call through

173 2018-05-28 Ed Schonberg <schonberg@adacore.com>
175 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
176 when bounds of fixed type are static, to remove some spuerfluous
177 implicit conversions and provide an accurate result when converting
178 back and forth between the fixed point type and a floating point type.
180 2018-05-28 Ed Schonberg <schonberg@adacore.com>
182 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
185 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
187 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
188 replaced, if any; all callers changed.
189 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
190 constant with private view so we take the address of that entity.
191 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
192 any; all callers changed. Handle N_Indexed_Component like
193 N_Attribute_Reference. Add N_Type_Conversion case.
194 (Visit_Node): Indexed references can be uplevel if the type isn't
196 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
197 been relocated, set first_named pointer in original node as well.
199 2018-05-28 Ed Schonberg <schonberg@adacore.com>
201 * exp_aggr.adb (Flatten): Copy tree of expression in a component
202 association with a range or a set of discrete choices, rather than
203 relocating the node. This avoids inconsistencies in the tree when
204 handling nested subprograms with uplevel references for LLVM.
206 2018-05-28 Arnaud Charlet <charlet@adacore.com>

218 unnecessary use of 'Unrestricted_Access.
220 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
222 * repinfo.adb (Expr_Value_S): New routine.

257 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
259 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
260 the declarations of single concurrent types because they fall in the
261 category of full type and object declarations.

270 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
271 includes a call to function to which it applies. This may mean an
272 omission of an attribute reference 'Result, in particular if the
273 function is pqrameterless.
275 2018-05-28 Justin Squirek <squirek@adacore.com>
277 * sem_ch8.adb (Find_Expanded_Name): Add extra guard to make sure the
278 misresolved package name is not a case of mistaken identity.

282 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
283 GNATprove mode, as the order of resolution (low then high) means that
284 all the information is not available when resolving the low bound the
287 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
289 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
290 end with the linker section, if any.
291 (List_Entities): Do not output the linker section for record types,
292 array types and variables.
293 (Print_Expr): Factor out common processing for unary operators and
294 special values. Adjust and reorder the various cases.
295 (List_Object_Info): End with the linker section, if any.

308 Expand range of type to match the address space of the target.
309 (Task_Storage_Size): Remove unused type.
311 2018-05-25 Ed Schonberg <schonberg@adacore.com>
313 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
314 of a fixed point type and the parent is a multiplying operation,
315 resolve the operand with its own type because the context will impose a
316 resulting type on the result of the multiplication by means of
317 approriate conversion.
319 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
321 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
322 the in-place initialization aggregate created for pragmas
323 Initialize_Scalars or Normalize_Scalars is performed with checks
326 2018-05-25 Arnaud Charlet <charlet@adacore.com>
328 * exp_aggr.adb (Convert_To_Positional): Bump default for
329 Max_Others_Replicate to 32. Update comments.
330 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
331 (No_File_Info_Cache): Initialize separately.
332 * osint.adb (No_File_Info_Cache): Update initializer.
334 2018-05-25 Javier Miranda <miranda@adacore.com>
336 * sem_res.adb (Resolve_Membership_Op): Allow the use of the membership
337 test when the left operand is a class-wide interface and the right
338 operand is not a class-wide type.
339 * exp_ch4.adb (Tagged_Membership): Adding support for interface as the
342 2018-05-25 Ed Schonberg <schonberg@adacore.com>
344 * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated
345 in an others clause to prevent visibility issues with the generated
347 (Component_OK_For_Backend): Return false for a quantified expression.

350 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
352 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
353 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
354 into three distring cases rather than in one loop which attempts to
355 handle all three cases. This rewrite eliminates an issue where the last
356 frame of the stack cannot be freed, thus causing the memory range of a
357 new frame to approach the overflow point of the memory index type.
358 Since the overflow is logically treated as a
359 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
360 (SS_Allocate_Static): New routine. The routine factorizes the static
361 secondary stack-related code from the former SS_Allocate.
363 2018-05-25 Sergey Rybin <rybin@adacore.com>
365 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'

370 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
371 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
372 is created when the proper body of the stub is analyzed.
373 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
374 is the proper body of a subunit, the cloned body must be inserted in
375 the declarative list that contains the stub.
377 2018-05-25 Justin Squirek <squirek@adacore.com>
379 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
380 generate code for 6.5(8-10) so that we don't get an assertion error
381 when dealing with an incomplete return type.
383 2018-05-25 Arnaud Charlet <charlet@adacore.com>
385 * pprint.adb (Expression_Name): Strip too long expressions to avoid
386 carrying very large strings.
388 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
390 * switch-b.adb (Scan_Binder_Switches): binder switch -Q accepts Natural
393 2018-05-25 Doug Rupp <rupp@adacore.com>
395 * tracebak.c (aarch64-linux): Implement.
397 2018-05-25 Justin Squirek <squirek@adacore.com>

412 2018-05-25 Ed Schonberg <schonberg@adacore.com>
414 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
415 Validate_Derived_Type_Instance, to verify that all interfaces
416 implemented by the formal type are also implemented by the actual. The
417 verification is complicated when an interface of the formal is declared
418 in a generic unit and the actual is declared in an instance of it.
419 There is currently no mechanism to relate an interface declared within
420 a generic to the corresponding interface in an instance, so we must
421 traverse the list of interfaces of the actual, looking for a name
422 match, and verifying that that interface is declared in an instance.
424 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
426 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
427 assertions; replace function versions of Next_Formal/Next_Actual with
428 their procedural versions (which are more concise).

469 <E_Record_Type>: Force the size of a storage unit on empty classes.
470 * gcc-interface/utils.c (make_type_from_size) <BOOLEAN_TYPE>: Skip
471 boolean types with precision 1 if the size is the expected one.

493 in loops at the library level.
495 2018-05-25 Ed Schonberg <schonberg@adacore.com>
497 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
498 declaration is inserted into the tree and analyzed at that point, so
499 should not be reinserted when the body is constructed. Inside a
500 generic, ensure that the body is not inserted twice in the tree.
502 2018-05-25 Yannick Moy <moy@adacore.com>

538 body of a variant record equality renaming.

1658 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
1659 delegate the secondary stack management when there is no suitable
1660 transient context, and the transient scope was intended to manage the

1665 the comment on usage.
1666 (Find_Transient_Context): Change the initinte loop into a while loop.

1672 routine Find_Transient_Context.
1673 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly

2048 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2049 confusion with the with clause attribute by the same name.
2050 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
2051 * rtsfind.adb (Maybe_Add_With): Code cleanup.
2052 * sem_ch8.adb (Present_System_Aux): Code cleanup.
2053 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
2055 (Implicit_With_On_Parent): Mark the with clause as generated for a
2057 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
2058 instantiation are no longer marked as Implicit_With_From_Instantiation
2059 because they are already marked as implicit.
2060 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
2061 which marks implicit with clauses as related to an instantiation.
2062 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2063 (Parent_With): New routine.
2064 (Set_Implicit_With_From_Instantiation): Removed.
2065 (Set_Parent_With): New routine.
2066 * sinfo.ads: Update the documentation of attribute Implicit_With.
2067 Remove attribute Implicit_With_From_Instantiation along with
2068 occurrences in nodes. Add attribute Parent_With along with occurrences
2070 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
2071 (Parent_With): New routine along with pragma Inline.
2072 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
2073 (Set_Parent_With): New routine along with pragma Inline.
2075 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2077 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
2078 entity when the enclosing construct is a body.
2080 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2082 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2083 Secondary_Stack_Size handling as a pragma is now generated for the
2084 corresponding aspect instead of an attribute. Pragma expression is
2085 relocated instead of evaluated. Discriminant of the corresponding
2086 record type is referenced rather than the type discriminant.
2087 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2088 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2089 * sem_ch13.adb (Analyze_One_Aspect): Transform
2090 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2091 because the attribute does not have visibility on a task type's
2092 discriminants when the type's definition is expanded.
2093 (Analyze_Attribute_Definition_Clause): Remove handling of
2094 Attribute_Secondary_Stack_Size.
2095 * snames.adb-tmpl, snames.ads-tmpl: Remove
2096 Attribute_Secondary_Stack_Size, no longer used.
2098 2018-01-11 Justin Squirek <squirek@adacore.com>
2100 * sem_ch8.adb: Minor comment fix.
2102 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2104 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
2105 individual action because the action may denote a complex expression,
2106 such as a case statement, which in turn may contain additional
2109 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2111 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2112 analysis on a copy of the expression with a copy of the index variable,
2113 because full expansion will rewrite construct into a loop with the
2114 original loop variable.
2115 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2116 expression is an iterated component association. Full analysis takes
2117 place when construct is rewritten as a loop.
2118 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2119 is not safe for in-place assignment.
2120 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
2121 entity with no homonym and no other entity in the scope.
2123 2018-01-11 Justin Squirek <squirek@adacore.com>
2125 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
2126 message to be printed on the pragma argument identifier.
2128 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2130 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
2131 entity of the generated invariant procedure in order to construct a
2132 proper entity chain.
2134 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
2136 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
2139 2018-01-11 Arnaud Charlet <charlet@adacore.com>
2141 * einfo.ads, einfo.adb (Activation_Record_Component,
2142 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
2143 Allow E_Discriminant.
2145 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
2147 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
2148 for atomic access once the component size is taken into account and
2149 also do it if the component type is Atomic or Volatile_Full_Access.
2151 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
2153 * gnatvsn.ads: Bump copyright year.

2156 Alan Hayward <alan.hayward@arm.com>
2157 David Sherwood <david.sherwood@arm.com>

2170 Alan Hayward <alan.hayward@arm.com>
2171 David Sherwood <david.sherwood@arm.com>
2173 * gcc-interface/utils.c (gnat_types_compatible_p): Handle
2174 polynomial TYPE_VECTOR_SUBPARTS.

2177 Alan Hayward <alan.hayward@arm.com>
