388 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
389 any; all callers changed. Handle N_Indexed_Component like
390 N_Attribute_Reference. Add N_Type_Conversion case.
391 (Visit_Node): Indexed references can be uplevel if the type isn't
393 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
394 been relocated, set first_named pointer in original node as well.

549 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
550 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
551 into three distring cases rather than in one loop which attempts to
552 handle all three cases. This rewrite eliminates an issue where the last
553 frame of the stack cannot be freed, thus causing the memory range of a
554 new frame to approach the overflow point of the memory index type.
555 Since the overflow is logically treated as a
556 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
557 (SS_Allocate_Static): New routine. The routine factorizes the static
558 secondary stack-related code from the former SS_Allocate.

571 is the proper body of a subunit, the cloned body must be inserted in
572 the declarative list that contains the stub.

611 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
612 Validate_Derived_Type_Instance, to verify that all interfaces
613 implemented by the formal type are also implemented by the actual. The
614 verification is complicated when an interface of the formal is declared
615 in a generic unit and the actual is declared in an instance of it.
616 There is currently no mechanism to relate an interface declared within
617 a generic to the corresponding interface in an instance, so we must
618 traverse the list of interfaces of the actual, looking for a name
619 match, and verifying that that interface is declared in an instance.

1065 a constrained array component.
1066 * einfo.adb: Subprograms for Predicated_Parent.
1067 (Predicate_Function): Use new attribute.
1068 * exp_util.adb (Make_Predicate_Call): If the predicate function is not

1188 * sem_ch5.adb (Preanalyze_Range): The pre-analysis of the domain of
1189 iteration of an Ada2012 loop is performed to determine the type of the
1190 domain, but full analysis is performed once the loop is rewritten as a

1192 must also suppress the generation of freeze nodes, which may otherwise
1193 appear in the wrong scope before rewritting.

2026 take place inside a protected function.
2027 (Diagnose_Non_Variable_Lhs): Use Within_Function to check for an
2029 (Is_Protected_Part_Of_Constituent): New routine.
2030 (Within_Function): New routine.

2034 Bump copyright notices to 2018.
2036 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2038 * binde.adb, par-ch6.adb, par-ch9.adb, sem_ch12.adb, sem_ch13.adb:
2041 2018-01-11 Justin Squirek <squirek@adacore.com>
2043 * par-ch6.adb (Scan_Body_Or_Expression_Function): Add additional check
2044 to make sure a given expression function is properly parenthesized.
2046 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2048 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Check the
2049 categorization of a subprogram body which does not complete a previous
2052 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2054 * sem_ch10.adb (Check_Private_Child_Unit): Ensure that the enclosing
2055 scope of package Ada is Standard.
2057 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2059 * sem_ch13.adb (Replace_Type_Ref): Handle properly reference to a
2060 subcomponent of the current entity when building the body for a dynamic
2061 predicate function for a record with composite subcomponents.
2063 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2065 * exp_aggr.adb (Convert_Aggr_In_Object_Decl): Update the call to
2066 Establish_Transient_Scope.
2067 (Convert_To_Assignments): Update the call to Establish_Transient_Scope.

2071 (Make_Build_In_Place_Call_In_Object_Declaration): Update the call to
2072 Establish_Transient_Scope.
2073 * exp_ch7.adb (Establish_Transient_Scope): Restructured. Delegate the
2074 management of the secondary stack to an enclosing scope if there is no
2075 suitable construct to wrap, and the transient scope was intended to
2076 manage the secondary stack.
2077 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
2078 is a valid boundary for a transient expression which comes from the
2079 statements of the alternative, otherwise alternatives cannot be
2080 wrapped. Assignments of controlled objects which have controlled
2081 actions suppressed now stop the traversal as there is no point in
2082 looking for an enclosing construct. Add several N_xxx_Body choices to
2083 the termination conditions for completeness.
2084 * exp_ch7.ads (Establish_Transient_Scope): Update the parameter profile
2085 and the associated comment on usage.
2086 * exp_smem.adb (Add_Shared_Var_Lock_Procs): Update the call to
2087 Establish_Transient_Scope.
2088 (Add_Write_After): Update the call to Establish_Transient_Scope.
2089 * sem_res.adb (Check_Initialization_Call): Removed.
2090 (Resolve_Actuals): Account for additional cases where finalization
2091 actions are required by utilizing predicate Needs_Finalization rather
2093 (Resolve_Call): Type initialization procedures can now utilize
2094 transient scopes to manage the secondary stack, thus preventing leaks
2095 during initialization. Remove the previous kludgy algorithm which
2096 attempts to manage the secondary stack at the object creation site.
2098 2018-01-11 Jerome Lambourg <lambourg@adacore.com>
2100 * libgnat/g-soliop__qnx.ads: New.

2137 * gnat_rm.texi: Regenerate.
2139 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2141 * sem_ch12.adb (Check_Fixed_Point_Type): Do not apply check if the
2142 formsl type corresponding to the actual fixed point type is private,
2143 because in this case there can be no suspicious arithmetic operations
2144 in the generic unless they reference a formal subprogram. Clarify
2147 2018-01-11 Javier Miranda <miranda@adacore.com>
2149 * exp_util.adb (Remove_Side_Effects): No action done for functions
2150 returning class-wide types since it requires generating code using
2151 'reference and the CCG target has no secondary stack.
2152 * gnat1drv.adb: Disable building static dispatch tables when generating

2163 * libgnat/s-os_lib.adb (Normalize_Pathname): New implementation.
2165 2018-01-11 Bob Duff <duff@adacore.com>
2167 * doc/gnat_ugn/gnat_utility_programs.rst: Rewrite gnatpp documentation
2168 to match what the Libadalang-based version does.
2169 * doc/gnat_ugn/about_this_guide.rst: Update reference.
2171 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2173 * sem_res.adb (Uses_SS): A controlled type requires the secondary stack
2174 if it contains at least one component declaration employing a function
2175 call returning on the secondary stack.

2192 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2194 * sem_prag.adb (Analyze_Pragma, case Predicate): Indicate that the type
2195 has a delayed aspect which must be processed at the point the type is
2196 frozen. This mimics what is done when the predicate is provided by a

2212 Default_Sec_Stack_Size.
2213 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
2214 limit check so that the integer index does not overflow. Check the
2215 dynamic stack allocation does not cause the secondary stack pointer to
2217 (SS_Info): Align colons.
2218 (SS_Init): Cover the case when bootstraping with an old compiler that
2219 does not set Default_SS_Size.
2221 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2223 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
2224 legality of an inherited operation that may require overriding, ignore
2225 primitive_wrappers that correspond to explicit operations that override
2226 an interface primitive.
2227 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
2228 operation to which the class-wide expression applies is a protected op.
2229 with a primitive_wrapper, verify that the updated inherited expression
2230 does not contain an internal call to a protected function. This
2231 completes the implementation of AI12-0166.
2233 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2235 * ali.adb: Document the remaining letters available for ALI lines.
2236 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
2237 * ali.ads: Update type With_Record. Field
2238 Implicit_With_From_Instantiation is no longer in use. Add field
2240 * csinfo.adb (CSinfo): Remove the setup for attribute
2241 Implicit_With_From_Instantiation.
2242 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
2243 either implicitly or explicitly withed.
2244 (Is_Implicit_With_Clause): New routine.
2245 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
2246 confusion with the with clause attribute by the same name.
2247 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
2248 * rtsfind.adb (Maybe_Add_With): Code cleanup.
2249 * sem_ch8.adb (Present_System_Aux): Code cleanup.
2250 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
2252 (Implicit_With_On_Parent): Mark the with clause as generated for a
2254 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
2255 instantiation are no longer marked as Implicit_With_From_Instantiation
2256 because they are already marked as implicit.
2257 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
2258 which marks implicit with clauses as related to an instantiation.
2259 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
2260 (Parent_With): New routine.
2261 (Set_Implicit_With_From_Instantiation): Removed.
2262 (Set_Parent_With): New routine.
2263 * sinfo.ads: Update the documentation of attribute Implicit_With.
2264 Remove attribute Implicit_With_From_Instantiation along with

2275 entity when the enclosing construct is a body.
2277 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
2279 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
2280 Secondary_Stack_Size handling as a pragma is now generated for the
2281 corresponding aspect instead of an attribute. Pragma expression is
2282 relocated instead of evaluated. Discriminant of the corresponding
2283 record type is referenced rather than the type discriminant.
2284 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
2285 Secondary_Stack_Size rep item checks to only look for the pragma rep.
2286 * sem_ch13.adb (Analyze_One_Aspect): Transform
2287 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
2288 because the attribute does not have visibility on a task type's

2290 (Analyze_Attribute_Definition_Clause): Remove handling of
2291 Attribute_Secondary_Stack_Size.
2292 * snames.adb-tmpl, snames.ads-tmpl: Remove
2293 Attribute_Secondary_Stack_Size, no longer used.

2299 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2301 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
2302 individual action because the action may denote a complex expression,
2303 such as a case statement, which in turn may contain additional
2306 2018-01-11 Ed Schonberg <schonberg@adacore.com>
2308 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
2309 analysis on a copy of the expression with a copy of the index variable,
2310 because full expansion will rewrite construct into a loop with the
2311 original loop variable.
2312 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
2313 expression is an iterated component association. Full analysis takes
2314 place when construct is rewritten as a loop.
2315 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
2316 is not safe for in-place assignment.
2317 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
2318 entity with no homonym and no other entity in the scope.
2320 2018-01-11 Justin Squirek <squirek@adacore.com>
2322 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
2323 message to be printed on the pragma argument identifier.
2325 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
2327 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
2328 entity of the generated invariant procedure in order to construct a
2329 proper entity chain.

2338 * einfo.ads, einfo.adb (Activation_Record_Component,
2339 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
2340 Allow E_Discriminant.
2342 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
2344 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
2345 for atomic access once the component size is taken into account and
2346 also do it if the component type is Atomic or Volatile_Full_Access.
2348 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
