153 of actual have uplevel references.
155 2018-05-28 Ed Schonberg <schonberg@adacore.com>
157 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
158 they can appear as components of activation records.

177 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
178 value when converting a float value to a fixed-point value. This is
179 required for CCG because it handles fixed-point types by means of
180 unsigned integer type variables. The range check is now performed using
181 the integer value stored in this temporary.
183 2018-05-28 Yannick Moy <moy@adacore.com>

212 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
213 access-to-subprogram types, to indicate that an indirect call through
214 such a type requires an activation record when compiling for LLVM.
215 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
217 2018-05-28 Ed Schonberg <schonberg@adacore.com>
219 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
220 when bounds of fixed type are static, to remove some spuerfluous
221 implicit conversions and provide an accurate result when converting
222 back and forth between the fixed point type and a floating point type.
224 2018-05-28 Ed Schonberg <schonberg@adacore.com>
226 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
229 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
231 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
232 replaced, if any; all callers changed.
233 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
234 constant with private view so we take the address of that entity.
235 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
236 any; all callers changed. Handle N_Indexed_Component like
237 N_Attribute_Reference. Add N_Type_Conversion case.
238 (Visit_Node): Indexed references can be uplevel if the type isn't
240 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
241 been relocated, set first_named pointer in original node as well.
243 2018-05-28 Ed Schonberg <schonberg@adacore.com>
245 * exp_aggr.adb (Flatten): Copy tree of expression in a component
246 association with a range or a set of discrete choices, rather than
247 relocating the node. This avoids inconsistencies in the tree when
248 handling nested subprograms with uplevel references for LLVM.
250 2018-05-28 Arnaud Charlet <charlet@adacore.com>

262 unnecessary use of 'Unrestricted_Access.

314 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
315 includes a call to function to which it applies. This may mean an
316 omission of an attribute reference 'Result, in particular if the
317 function is pqrameterless.
319 2018-05-28 Justin Squirek <squirek@adacore.com>
321 * sem_ch8.adb (Find_Expanded_Name): Add extra guard to make sure the

326 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
327 GNATprove mode, as the order of resolution (low then high) means that
328 all the information is not available when resolving the low bound the
331 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
333 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
334 end with the linker section, if any.
335 (List_Entities): Do not output the linker section for record types,
336 array types and variables.
337 (Print_Expr): Factor out common processing for unary operators and
338 special values. Adjust and reorder the various cases.
339 (List_Object_Info): End with the linker section, if any.

345 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
346 that the result will be either -infinite or +infinite.
348 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
350 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,

352 Expand range of type to match the address space of the target.
353 (Task_Storage_Size): Remove unused type.
355 2018-05-25 Ed Schonberg <schonberg@adacore.com>
357 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
358 of a fixed point type and the parent is a multiplying operation,
359 resolve the operand with its own type because the context will impose a
360 resulting type on the result of the multiplication by means of
361 approriate conversion.
363 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
365 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
366 the in-place initialization aggregate created for pragmas
367 Initialize_Scalars or Normalize_Scalars is performed with checks
370 2018-05-25 Arnaud Charlet <charlet@adacore.com>
372 * exp_aggr.adb (Convert_To_Positional): Bump default for
373 Max_Others_Replicate to 32. Update comments.
374 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
375 (No_File_Info_Cache): Initialize separately.

396 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
397 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
398 into three distring cases rather than in one loop which attempts to
399 handle all three cases. This rewrite eliminates an issue where the last
400 frame of the stack cannot be freed, thus causing the memory range of a
401 new frame to approach the overflow point of the memory index type.
402 Since the overflow is logically treated as a
403 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
404 (SS_Allocate_Static): New routine. The routine factorizes the static
405 secondary stack-related code from the former SS_Allocate.
407 2018-05-25 Sergey Rybin <rybin@adacore.com>

414 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
415 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
416 is created when the proper body of the stub is analyzed.
417 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
418 is the proper body of a subunit, the cloned body must be inserted in
419 the declarative list that contains the stub.
421 2018-05-25 Justin Squirek <squirek@adacore.com>
423 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
424 generate code for 6.5(8-10) so that we don't get an assertion error
425 when dealing with an incomplete return type.
427 2018-05-25 Arnaud Charlet <charlet@adacore.com>

430 carrying very large strings.

458 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
459 Validate_Derived_Type_Instance, to verify that all interfaces
460 implemented by the formal type are also implemented by the actual. The
461 verification is complicated when an interface of the formal is declared
462 in a generic unit and the actual is declared in an instance of it.
463 There is currently no mechanism to relate an interface declared within
464 a generic to the corresponding interface in an instance, so we must
465 traverse the list of interfaces of the actual, looking for a name
466 match, and verifying that that interface is declared in an instance.
468 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
470 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
471 assertions; replace function versions of Next_Formal/Next_Actual with

1702 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
1703 delegate the secondary stack management when there is no suitable
1704 transient context, and the transient scope was intended to manage the

1709 the comment on usage.
1710 (Find_Transient_Context): Change the initinte loop into a while loop.

1716 routine Find_Transient_Context.

2041 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
2042 has a delayed aspect which must be processed at the point the type is
2043 frozen. This mimics what is done when the predicate is provided by a
2046 2018-01-11 Doug Rupp <rupp@adacore.com>
2048 * init.c (vxworks): Add macro checks for __aarch64__.
2050 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2052 * exp_util.adb (Add_Failure_Expression): New routine.
2053 (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
2054 * sem_util.adb (Is_Current_Instance): Code cleanup.
2056 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2058 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
2059 Default_Sec_Stack_Size.
2060 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
2061 limit check so that the integer index does not overflow. Check the
2062 dynamic stack allocation does not cause the secondary stack pointer to
2064 (SS_Info): Align colons.
2065 (SS_Init): Cover the case when bootstraping with an old compiler that
2066 does not set Default_SS_Size.
2068 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2070 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
2071 legality of an inherited operation that may require overriding, ignore
2072 primitive_wrappers that correspond to explicit operations that override
2073 an interface primitive.
2074 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
2075 operation to which the class-wide expression applies is a protected op.
2076 with a primitive_wrapper, verify that the updated inherited expression
2077 does not contain an internal call to a protected function. This
2078 completes the implementation of AI12-0166.
2080 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2082 * ali.adb: Document the remaining letters available for ALI lines.
2083 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
2084 * ali.ads: Update type With_Record. Field
2085 Implicit_With_From_Instantiation is no longer in use. Add field
2087 * csinfo.adb (CSinfo): Remove the setup for attribute
2088 Implicit_With_From_Instantiation.
2089 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
2090 either implicitly or explicitly withed.
2091 (Is_Implicit_With_Clause): New routine.
2092 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2093 confusion with the with clause attribute by the same name.
2094 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
2095 * rtsfind.adb (Maybe_Add_With): Code cleanup.
2096 * sem_ch8.adb (Present_System_Aux): Code cleanup.
2097 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
2099 (Implicit_With_On_Parent): Mark the with clause as generated for a
2101 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
2102 instantiation are no longer marked as Implicit_With_From_Instantiation
2103 because they are already marked as implicit.
2104 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
2105 which marks implicit with clauses as related to an instantiation.
2106 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2107 (Parent_With): New routine.
2108 (Set_Implicit_With_From_Instantiation): Removed.
2109 (Set_Parent_With): New routine.
2110 * sinfo.ads: Update the documentation of attribute Implicit_With.
2111 Remove attribute Implicit_With_From_Instantiation along with
2112 occurrences in nodes. Add attribute Parent_With along with occurrences
2114 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
2115 (Parent_With): New routine along with pragma Inline.
2116 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
2117 (Set_Parent_With): New routine along with pragma Inline.
2119 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2121 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
2122 entity when the enclosing construct is a body.
2124 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2126 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2127 Secondary_Stack_Size handling as a pragma is now generated for the
2128 corresponding aspect instead of an attribute. Pragma expression is
2129 relocated instead of evaluated. Discriminant of the corresponding
2130 record type is referenced rather than the type discriminant.
2131 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2132 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2133 * sem_ch13.adb (Analyze_One_Aspect): Transform
2134 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2135 because the attribute does not have visibility on a task type's
2136 discriminants when the type's definition is expanded.
2137 (Analyze_Attribute_Definition_Clause): Remove handling of
2138 Attribute_Secondary_Stack_Size.
2139 * snames.adb-tmpl, snames.ads-tmpl: Remove
2140 Attribute_Secondary_Stack_Size, no longer used.
2142 2018-01-11 Justin Squirek <squirek@adacore.com>
2144 * sem_ch8.adb: Minor comment fix.
2146 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2148 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
2149 individual action because the action may denote a complex expression,
2150 such as a case statement, which in turn may contain additional
2153 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2155 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2156 analysis on a copy of the expression with a copy of the index variable,
2157 because full expansion will rewrite construct into a loop with the
2158 original loop variable.
2159 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2160 expression is an iterated component association. Full analysis takes
2161 place when construct is rewritten as a loop.
2162 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2163 is not safe for in-place assignment.
2164 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
2165 entity with no homonym and no other entity in the scope.
2167 2018-01-11 Justin Squirek <squirek@adacore.com>
2169 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
2170 message to be printed on the pragma argument identifier.
2172 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2174 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
2175 entity of the generated invariant procedure in order to construct a
2176 proper entity chain.
2178 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
2180 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
2183 2018-01-11 Arnaud Charlet <charlet@adacore.com>
2185 * einfo.ads, einfo.adb (Activation_Record_Component,
2186 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
2187 Allow E_Discriminant.
2189 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
2191 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
2192 for atomic access once the component size is taken into account and
2193 also do it if the component type is Atomic or Volatile_Full_Access.
2195 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
2197 * gnatvsn.ads: Bump copyright year.
2199 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
2200 Alan Hayward <alan.hayward@arm.com>
2201 David Sherwood <david.sherwood@arm.com>
2203 * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_BITSIZE
2206 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
2207 Alan Hayward <alan.hayward@arm.com>
2208 David Sherwood <david.sherwood@arm.com>
2210 * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_PRECISION
2213 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
2214 Alan Hayward <alan.hayward@arm.com>
2215 David Sherwood <david.sherwood@arm.com>
2217 * gcc-interface/utils.c (gnat_types_compatible_p): Handle
2218 polynomial TYPE_VECTOR_SUBPARTS.
2220 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
2221 Alan Hayward <alan.hayward@arm.com>
2222 David Sherwood <david.sherwood@arm.com>
2224 * gcc-interface/misc.c (enumerate_modes): Handle polynomial
2227 2018-01-03 Jakub Jelinek <jakub@redhat.com>
2229 Update copyright years.
2231 * gnat_ugn.texi: Bump @copying's copyright year.
2232 * gnat_rm.texi: Likewise.
