147 of actual have uplevel references.
149 2018-05-28 Ed Schonberg <schonberg@adacore.com>
151 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
152 they can appear as components of activation records.

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

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

209 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
211 2018-05-28 Ed Schonberg <schonberg@adacore.com>
213 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
214 when bounds of fixed type are static, to remove some spuerfluous
215 implicit conversions and provide an accurate result when converting
216 back and forth between the fixed point type and a floating point type.
218 2018-05-28 Ed Schonberg <schonberg@adacore.com>
220 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
223 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
225 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
226 replaced, if any; all callers changed.
227 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
228 constant with private view so we take the address of that entity.
229 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
230 any; all callers changed. Handle N_Indexed_Component like
231 N_Attribute_Reference. Add N_Type_Conversion case.
232 (Visit_Node): Indexed references can be uplevel if the type isn't
234 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
235 been relocated, set first_named pointer in original node as well.
237 2018-05-28 Ed Schonberg <schonberg@adacore.com>
239 * exp_aggr.adb (Flatten): Copy tree of expression in a component
240 association with a range or a set of discrete choices, rather than
241 relocating the node. This avoids inconsistencies in the tree when
242 handling nested subprograms with uplevel references for LLVM.

256 unnecessary use of 'Unrestricted_Access.

308 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
309 includes a call to function to which it applies. This may mean an
310 omission of an attribute reference 'Result, in particular if the
311 function is pqrameterless.
313 2018-05-28 Justin Squirek <squirek@adacore.com>
315 * sem_ch8.adb (Find_Expanded_Name): Add extra guard to make sure the

320 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
321 GNATprove mode, as the order of resolution (low then high) means that
322 all the information is not available when resolving the low bound the

327 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
328 end with the linker section, if any.
329 (List_Entities): Do not output the linker section for record types,
330 array types and variables.
331 (Print_Expr): Factor out common processing for unary operators and
332 special values. Adjust and reorder the various cases.
333 (List_Object_Info): End with the linker section, if any.

346 Expand range of type to match the address space of the target.

349 2018-05-25 Ed Schonberg <schonberg@adacore.com>
351 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
352 of a fixed point type and the parent is a multiplying operation,
353 resolve the operand with its own type because the context will impose a
354 resulting type on the result of the multiplication by means of
355 approriate conversion.
357 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
359 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
360 the in-place initialization aggregate created for pragmas
361 Initialize_Scalars or Normalize_Scalars is performed with checks
364 2018-05-25 Arnaud Charlet <charlet@adacore.com>
366 * exp_aggr.adb (Convert_To_Positional): Bump default for
367 Max_Others_Replicate to 32. Update comments.
368 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
369 (No_File_Info_Cache): Initialize separately.

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

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

424 carrying very large strings.

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

1572 (Unit_Entity): New routine.
1573 * sem_prag.adb (Analyze_Pragma): Reimplement the handling of pragma
1574 Elaboration_Checks. The analysis now ensures that the pragma appears at
1575 the configuration level, and on the initial declaration of a unit.
1576 Other placements are either flagged as illegal, or ignored.
1577 (Check_Duplicate_Elaboration_Checks_Pragma): New routine.

1637 address/offset type changes.
1638 (Aranges_Lookup): Likewise.

1691 attribute reference is legal within a generic unit when the prefix is a
1692 formal private type.
1694 2018-05-21 Hristian Kirtchev <kirtchev@adacore.com>
1696 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
1697 delegate the secondary stack management when there is no suitable
1698 transient context, and the transient scope was intended to manage the

1700 transient scope creation logic by special casing assignment statements
1701 of controlled components for type initialization procedures.
1702 (Find_Node_To_Be_Wrapped): Renamed to Find_Transient_Context. Update
1703 the comment on usage.
1704 (Find_Transient_Context): Change the initinte loop into a while loop.
1705 Iterations schemes and iterator specifications are not valid transient
1706 contexts because they rely on special processing. Assignment statements
1707 are now treated as a normal transient context, special cases are
1708 handled by the caller. Add special processing for pragma Check.
1709 (Is_OK_Construct): Removed. Its functionality has been merged in
1710 routine Find_Transient_Context.
1711 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly
1712 retrieve the subprogram being invoked. Use a more accurate predicate

1835 * exp_ch6.adb (Make_Build_In_Place_Call_In_Object_Declaration): Handle
1836 properly object declarations with initializations that are
1837 build-in-place function calls, when there is an address specification,

1916 suitable construct to wrap, and the transient scope was intended to
1917 manage the secondary stack.
1918 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
1919 is a valid boundary for a transient expression which comes from the
1920 statements of the alternative, otherwise alternatives cannot be

1922 actions suppressed now stop the traversal as there is no point in
1923 looking for an enclosing construct. Add several N_xxx_Body choices to
1924 the termination conditions for completeness.

1931 (Resolve_Actuals): Account for additional cases where finalization
1932 actions are required by utilizing predicate Needs_Finalization rather
1934 (Resolve_Call): Type initialization procedures can now utilize
1935 transient scopes to manage the secondary stack, thus preventing leaks
1936 during initialization. Remove the previous kludgy algorithm which
1937 attempts to manage the secondary stack at the object creation site.

2042 * init.c (vxworks): Add macro checks for __aarch64__.
2044 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2046 * exp_util.adb (Add_Failure_Expression): New routine.
2047 (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
2048 * sem_util.adb (Is_Current_Instance): Code cleanup.
2050 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2052 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
2053 Default_Sec_Stack_Size.
2054 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
2055 limit check so that the integer index does not overflow. Check the
2056 dynamic stack allocation does not cause the secondary stack pointer to
2058 (SS_Info): Align colons.
2059 (SS_Init): Cover the case when bootstraping with an old compiler that
2060 does not set Default_SS_Size.
2062 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2064 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
2065 legality of an inherited operation that may require overriding, ignore
2066 primitive_wrappers that correspond to explicit operations that override
2067 an interface primitive.
2068 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
2069 operation to which the class-wide expression applies is a protected op.
2070 with a primitive_wrapper, verify that the updated inherited expression
2071 does not contain an internal call to a protected function. This
2072 completes the implementation of AI12-0166.
2074 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2076 * ali.adb: Document the remaining letters available for ALI lines.
2077 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
2078 * ali.ads: Update type With_Record. Field
2079 Implicit_With_From_Instantiation is no longer in use. Add field
2081 * csinfo.adb (CSinfo): Remove the setup for attribute
2082 Implicit_With_From_Instantiation.
2083 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
2084 either implicitly or explicitly withed.
2085 (Is_Implicit_With_Clause): New routine.
2086 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2087 confusion with the with clause attribute by the same name.
2088 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
2089 * rtsfind.adb (Maybe_Add_With): Code cleanup.
2090 * sem_ch8.adb (Present_System_Aux): Code cleanup.
2091 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
2093 (Implicit_With_On_Parent): Mark the with clause as generated for a
2095 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
2096 instantiation are no longer marked as Implicit_With_From_Instantiation
2097 because they are already marked as implicit.
2098 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
2099 which marks implicit with clauses as related to an instantiation.
2100 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2101 (Parent_With): New routine.
2102 (Set_Implicit_With_From_Instantiation): Removed.
2103 (Set_Parent_With): New routine.
2104 * sinfo.ads: Update the documentation of attribute Implicit_With.
2105 Remove attribute Implicit_With_From_Instantiation along with
2106 occurrences in nodes. Add attribute Parent_With along with occurrences
2108 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
2109 (Parent_With): New routine along with pragma Inline.
2110 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
2111 (Set_Parent_With): New routine along with pragma Inline.
2113 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2115 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
2116 entity when the enclosing construct is a body.
2118 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2120 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2121 Secondary_Stack_Size handling as a pragma is now generated for the
2122 corresponding aspect instead of an attribute. Pragma expression is
2123 relocated instead of evaluated. Discriminant of the corresponding
2124 record type is referenced rather than the type discriminant.
2125 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2126 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2127 * sem_ch13.adb (Analyze_One_Aspect): Transform
2128 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2129 because the attribute does not have visibility on a task type's
2130 discriminants when the type's definition is expanded.
2131 (Analyze_Attribute_Definition_Clause): Remove handling of
2132 Attribute_Secondary_Stack_Size.
2133 * snames.adb-tmpl, snames.ads-tmpl: Remove
2134 Attribute_Secondary_Stack_Size, no longer used.
2136 2018-01-11 Justin Squirek <squirek@adacore.com>
2138 * sem_ch8.adb: Minor comment fix.
2140 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2142 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
2143 individual action because the action may denote a complex expression,
2144 such as a case statement, which in turn may contain additional
2147 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2149 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2150 analysis on a copy of the expression with a copy of the index variable,
2151 because full expansion will rewrite construct into a loop with the
2152 original loop variable.
2153 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2154 expression is an iterated component association. Full analysis takes
2155 place when construct is rewritten as a loop.
2156 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2157 is not safe for in-place assignment.
2158 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
2159 entity with no homonym and no other entity in the scope.
2161 2018-01-11 Justin Squirek <squirek@adacore.com>
2163 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
2164 message to be printed on the pragma argument identifier.
2166 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2168 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
2169 entity of the generated invariant procedure in order to construct a
2170 proper entity chain.
2172 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
2174 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
2177 2018-01-11 Arnaud Charlet <charlet@adacore.com>
2179 * einfo.ads, einfo.adb (Activation_Record_Component,
2180 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
2181 Allow E_Discriminant.
2183 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
2185 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
2186 for atomic access once the component size is taken into account and
2187 also do it if the component type is Atomic or Volatile_Full_Access.
2189 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
2191 * gnatvsn.ads: Bump copyright year.
2193 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
2194 Alan Hayward <alan.hayward@arm.com>
2195 David Sherwood <david.sherwood@arm.com>
2197 * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_BITSIZE
2200 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
2201 Alan Hayward <alan.hayward@arm.com>
2202 David Sherwood <david.sherwood@arm.com>
2204 * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_PRECISION

2208 Alan Hayward <alan.hayward@arm.com>
2209 David Sherwood <david.sherwood@arm.com>
2211 * gcc-interface/utils.c (gnat_types_compatible_p): Handle
2212 polynomial TYPE_VECTOR_SUBPARTS.
2214 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
2215 Alan Hayward <alan.hayward@arm.com>
2216 David Sherwood <david.sherwood@arm.com>
2218 * gcc-interface/misc.c (enumerate_modes): Handle polynomial
2221 2018-01-03 Jakub Jelinek <jakub@redhat.com>
2223 Update copyright years.
2225 * gnat_ugn.texi: Bump @copying's copyright year.
2226 * gnat_rm.texi: Likewise.
