157 of actual have uplevel references.
159 2018-05-28 Ed Schonberg <schonberg@adacore.com>
161 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
162 they can appear as components of activation records.

181 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
182 value when converting a float value to a fixed-point value. This is
183 required for CCG because it handles fixed-point types by means of
184 unsigned integer type variables. The range check is now performed using
185 the integer value stored in this temporary.
187 2018-05-28 Yannick Moy <moy@adacore.com>

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

219 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
221 2018-05-28 Ed Schonberg <schonberg@adacore.com>
223 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
224 when bounds of fixed type are static, to remove some spuerfluous
225 implicit conversions and provide an accurate result when converting
226 back and forth between the fixed point type and a floating point type.
228 2018-05-28 Ed Schonberg <schonberg@adacore.com>
230 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
233 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
235 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
236 replaced, if any; all callers changed.
237 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
238 constant with private view so we take the address of that entity.
239 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
240 any; all callers changed. Handle N_Indexed_Component like
241 N_Attribute_Reference. Add N_Type_Conversion case.
242 (Visit_Node): Indexed references can be uplevel if the type isn't
244 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
245 been relocated, set first_named pointer in original node as well.
247 2018-05-28 Ed Schonberg <schonberg@adacore.com>
249 * exp_aggr.adb (Flatten): Copy tree of expression in a component
250 association with a range or a set of discrete choices, rather than
251 relocating the node. This avoids inconsistencies in the tree when
252 handling nested subprograms with uplevel references for LLVM.

266 unnecessary use of 'Unrestricted_Access.

318 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
319 includes a call to function to which it applies. This may mean an
320 omission of an attribute reference 'Result, in particular if the
321 function is pqrameterless.
323 2018-05-28 Justin Squirek <squirek@adacore.com>
325 * sem_ch8.adb (Find_Expanded_Name): Add extra guard to make sure the

330 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
331 GNATprove mode, as the order of resolution (low then high) means that
332 all the information is not available when resolving the low bound the
335 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
337 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
338 end with the linker section, if any.
339 (List_Entities): Do not output the linker section for record types,
340 array types and variables.
341 (Print_Expr): Factor out common processing for unary operators and
342 special values. Adjust and reorder the various cases.
343 (List_Object_Info): End with the linker section, if any.
344 (List_Record_Info): Likewise.
345 (List_Type_Info): Do not start with a blank line.
347 2018-05-25 Nicolas Roche <roche@adacore.com>
349 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
350 that the result will be either -infinite or +infinite.
352 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
354 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,

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

359 2018-05-25 Ed Schonberg <schonberg@adacore.com>
361 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
362 of a fixed point type and the parent is a multiplying operation,
363 resolve the operand with its own type because the context will impose a
364 resulting type on the result of the multiplication by means of
365 approriate conversion.
367 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
369 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
370 the in-place initialization aggregate created for pragmas
371 Initialize_Scalars or Normalize_Scalars is performed with checks
374 2018-05-25 Arnaud Charlet <charlet@adacore.com>
376 * exp_aggr.adb (Convert_To_Positional): Bump default for
377 Max_Others_Replicate to 32. Update comments.

398 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
400 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
401 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
402 into three distring cases rather than in one loop which attempts to
403 handle all three cases. This rewrite eliminates an issue where the last
404 frame of the stack cannot be freed, thus causing the memory range of a
405 new frame to approach the overflow point of the memory index type.
406 Since the overflow is logically treated as a
407 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
408 (SS_Allocate_Static): New routine. The routine factorizes the static
409 secondary stack-related code from the former SS_Allocate.
411 2018-05-25 Sergey Rybin <rybin@adacore.com>
413 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'

418 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
419 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
420 is created when the proper body of the stub is analyzed.
421 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
422 is the proper body of a subunit, the cloned body must be inserted in
423 the declarative list that contains the stub.
425 2018-05-25 Justin Squirek <squirek@adacore.com>
427 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
428 generate code for 6.5(8-10) so that we don't get an assertion error
429 when dealing with an incomplete return type.
431 2018-05-25 Arnaud Charlet <charlet@adacore.com>
433 * pprint.adb (Expression_Name): Strip too long expressions to avoid
434 carrying very large strings.

460 2018-05-25 Ed Schonberg <schonberg@adacore.com>
462 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
463 Validate_Derived_Type_Instance, to verify that all interfaces
464 implemented by the formal type are also implemented by the actual. The
465 verification is complicated when an interface of the formal is declared
466 in a generic unit and the actual is declared in an instance of it.
467 There is currently no mechanism to relate an interface declared within
468 a generic to the corresponding interface in an instance, so we must
469 traverse the list of interfaces of the actual, looking for a name
470 match, and verifying that that interface is declared in an instance.
472 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
474 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
475 assertions; replace function versions of Next_Formal/Next_Actual with
476 their procedural versions (which are more concise).

1706 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
1707 delegate the secondary stack management when there is no suitable
1708 transient context, and the transient scope was intended to manage the

1713 the comment on usage.
1714 (Find_Transient_Context): Change the initinte loop into a while loop.

1720 routine Find_Transient_Context.

1946 during initialization. Remove the previous kludgy algorithm which
1947 attempts to manage the secondary stack at the object creation site.

2041 sem_res.adb, sem_util.adb: Minor reformatting.
2043 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2045 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
2046 has a delayed aspect which must be processed at the point the type is
2047 frozen. This mimics what is done when the predicate is provided by a
2050 2018-01-11 Doug Rupp <rupp@adacore.com>
2052 * init.c (vxworks): Add macro checks for __aarch64__.
2054 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2056 * exp_util.adb (Add_Failure_Expression): New routine.
2057 (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
2058 * sem_util.adb (Is_Current_Instance): Code cleanup.
2060 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2062 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
2063 Default_Sec_Stack_Size.
2064 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
2065 limit check so that the integer index does not overflow. Check the
2066 dynamic stack allocation does not cause the secondary stack pointer to
2068 (SS_Info): Align colons.
2069 (SS_Init): Cover the case when bootstraping with an old compiler that
2070 does not set Default_SS_Size.
2072 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2074 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
2075 legality of an inherited operation that may require overriding, ignore
2076 primitive_wrappers that correspond to explicit operations that override
2077 an interface primitive.
2078 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
2079 operation to which the class-wide expression applies is a protected op.
2080 with a primitive_wrapper, verify that the updated inherited expression
2081 does not contain an internal call to a protected function. This
2082 completes the implementation of AI12-0166.
2084 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2086 * ali.adb: Document the remaining letters available for ALI lines.
2087 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
2088 * ali.ads: Update type With_Record. Field
2089 Implicit_With_From_Instantiation is no longer in use. Add field
2091 * csinfo.adb (CSinfo): Remove the setup for attribute
2092 Implicit_With_From_Instantiation.
2093 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
2094 either implicitly or explicitly withed.
2095 (Is_Implicit_With_Clause): New routine.
2096 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2097 confusion with the with clause attribute by the same name.
2098 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
2099 * rtsfind.adb (Maybe_Add_With): Code cleanup.
2100 * sem_ch8.adb (Present_System_Aux): Code cleanup.
2101 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
2103 (Implicit_With_On_Parent): Mark the with clause as generated for a
2105 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
2106 instantiation are no longer marked as Implicit_With_From_Instantiation
2107 because they are already marked as implicit.
2108 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
2109 which marks implicit with clauses as related to an instantiation.
2110 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2111 (Parent_With): New routine.
2112 (Set_Implicit_With_From_Instantiation): Removed.
2113 (Set_Parent_With): New routine.
2114 * sinfo.ads: Update the documentation of attribute Implicit_With.
2115 Remove attribute Implicit_With_From_Instantiation along with
2116 occurrences in nodes. Add attribute Parent_With along with occurrences
2118 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
2119 (Parent_With): New routine along with pragma Inline.
2120 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
2121 (Set_Parent_With): New routine along with pragma Inline.
2123 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2125 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
2126 entity when the enclosing construct is a body.
2128 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2130 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2131 Secondary_Stack_Size handling as a pragma is now generated for the
2132 corresponding aspect instead of an attribute. Pragma expression is
2133 relocated instead of evaluated. Discriminant of the corresponding
2134 record type is referenced rather than the type discriminant.
2135 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2136 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2137 * sem_ch13.adb (Analyze_One_Aspect): Transform
2138 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2139 because the attribute does not have visibility on a task type's
2140 discriminants when the type's definition is expanded.
2141 (Analyze_Attribute_Definition_Clause): Remove handling of
2142 Attribute_Secondary_Stack_Size.
2143 * snames.adb-tmpl, snames.ads-tmpl: Remove
2144 Attribute_Secondary_Stack_Size, no longer used.
2146 2018-01-11 Justin Squirek <squirek@adacore.com>
2148 * sem_ch8.adb: Minor comment fix.
2150 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2152 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
2153 individual action because the action may denote a complex expression,
2154 such as a case statement, which in turn may contain additional
2157 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2159 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2160 analysis on a copy of the expression with a copy of the index variable,
2161 because full expansion will rewrite construct into a loop with the
2162 original loop variable.
2163 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2164 expression is an iterated component association. Full analysis takes
2165 place when construct is rewritten as a loop.
2166 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2167 is not safe for in-place assignment.
2168 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
2169 entity with no homonym and no other entity in the scope.
2171 2018-01-11 Justin Squirek <squirek@adacore.com>
2173 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
2174 message to be printed on the pragma argument identifier.
2176 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2178 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
2179 entity of the generated invariant procedure in order to construct a
2180 proper entity chain.
2182 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
2184 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
2187 2018-01-11 Arnaud Charlet <charlet@adacore.com>
2189 * einfo.ads, einfo.adb (Activation_Record_Component,
2190 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
2191 Allow E_Discriminant.
2193 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
2195 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
2196 for atomic access once the component size is taken into account and
2197 also do it if the component type is Atomic or Volatile_Full_Access.
2199 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
2201 * gnatvsn.ads: Bump copyright year.
2203 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
2204 Alan Hayward <alan.hayward@arm.com>
2205 David Sherwood <david.sherwood@arm.com>
2207 * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_BITSIZE
2210 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
2211 Alan Hayward <alan.hayward@arm.com>
2212 David Sherwood <david.sherwood@arm.com>
2214 * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_PRECISION

2218 Alan Hayward <alan.hayward@arm.com>
2219 David Sherwood <david.sherwood@arm.com>
2221 * gcc-interface/utils.c (gnat_types_compatible_p): Handle
2222 polynomial TYPE_VECTOR_SUBPARTS.
2224 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
2225 Alan Hayward <alan.hayward@arm.com>
2226 David Sherwood <david.sherwood@arm.com>
2228 * gcc-interface/misc.c (enumerate_modes): Handle polynomial
2231 2018-01-03 Jakub Jelinek <jakub@redhat.com>
2233 Update copyright years.
2235 * gnat_ugn.texi: Bump @copying's copyright year.
2236 * gnat_rm.texi: Likewise.
