41 * contracts.adb (Analyze_Entry_Or_Subprogram_Contract): The
42 analysis of preconditions specified by pragmas (rather than
43 aspects) is not delayed, and therefore expressions functions
44 that are completions do not need special handling during

129 * sem_ch6.adb (Analyze_Subprogram_Body_Helper, Mask_Type):
130 Refine the handling of freezing types for expression functions
131 that are not completions, when analyzing the generated body for
132 the function: the body is inserted at the end of the enclosing
133 declarative part, and its analysis may freeze types declared in
134 the same scope that have not been frozen yet.
136 2018-08-21 Ed Schonberg <schonberg@adacore.com>
138 * sem_ch6.adb: Remove Freeze_Expr_Types.

160 2018-08-21 Ed Schonberg <schonberg@adacore.com>
162 * sem_ch6.adb (Check_Synchronized_Overriding): The conformance
163 between an overriding protected operation and the overridden
164 abstract progenitor operation requires subtype conformance;
165 requiring equality of return types in the case of a function is
166 too restrictive and leads to spurious errors when the return
167 type is a generic actual.

222 (Process_Path): Given an operation and a current state, call
223 Perm_Error if there is any mismatch.
224 (Return_Declarations, Return_Globals, Return_The_Global): Check
225 the state of a given name at the end of the subprogram. These
226 procedures may change depending on how we shall finally deal
227 with globals and the rhs state in a move operation.
228 (Set_Perm_Extensions, Set_Perm_Prefixes_Borrow,
229 Set_Perm_Prefixes, Setup_Globals, Setup_Parameter_Or_Global,

732 * exp_ch13.adb (Expand_N_Freeze_Entity): Handle subtype declared for an
734 * freeze.adb (Freeze_Expression): Handle freeze of an entity defined
735 outside of a subprogram body. This case was previously handled during
736 preanalysis; the frozen entities were remembered and left pending until
737 we continued freezeing entities outside of the subprogram. Now, when
738 climbing the parents chain to locate the correct placement for the
739 freezeing node, we check if the entity can be frozen and only when no
740 enclosing node is marked as Must_Not_Freeze the entity is frozen.

743 * sem_ch3.adb (Preanalyze_Default_Expression): Code adjusted to invoke
744 the new subprogram Preanalyze_With_Freezing_And_Resolve.

746 (Analyze_Expression_Function, Process_Formals): Invoke
747 Preanalyze_Formal_Expression instead of Preanalyze_Spec_Expression
748 since the analysis of the formals may freeze entities.

750 class-wide clone for eliminated subprograms.
751 * sem_res.ads, sem_res.adb (Preanalyze_And_Resolve): New subprogram.
752 Its code is basically the previous version of this routine but extended
753 with an additional parameter which is used to specify if during
754 preanalysis we are allowed to freeze entities. If the new parameter is
755 True then the subtree root node is marked as Must_Not_Freeze and no
756 entities are frozen during preanalysis.
757 (Preanalyze_And_Resolve): Invokes the internal version of
758 Preanalyze_And_Resolve without entity freezing.
759 (Preanalyze_With_Freezing_And_Resolve): Invokes the internal version of
760 Prenalyze_And_Resolve with freezing enabled.

794 enclosing scope already handles the secondary stack, take into account
795 transient blocks nested in a block that do not manage the secondary
796 stack and are located within a loop.
798 2018-07-17 Ed Schonberg <schonberg@adacore.com>
800 * sem_util.adb (Enclosing_Subprogram): Protected entries and task
801 entries must be treated separately: task entries are within the

1676 and protected operations.
1678 2018-05-31 Ed Schonberg <schonberg@adacore.com>
1680 * exp_ch4.adb (Expand_Modular_Addition, Expand_Modular_Subtraction):
1681 Convert all operands of the generated code to Standard.Unsigned, to
1682 prevent spurious visibility errors. This is needed when the generated
1683 expansion involves a modular index type of an array type, and the index
1684 type is not immediately visible.

1747 (Start_Search): Modify to use Start_Search_Internal
1748 (Start_Search_Internal): Add to break out an extra flag for searching

1821 comment about the memset case.
1823 2018-05-30 Bob Duff <duff@adacore.com>
1825 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
1826 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
1827 We need to analyze it as part of analyzing the block, so that if the
1828 call to Element that initializes Elmt_Decl returns on the secondary
1829 stack, the block will ss_mark/ss_release. This block is inside the
1830 loop; we don't want to leak memory until the loop exits. The purpose
1831 of analyzing Elmt_Decl first was to catch the error of modifying it,
1832 which is illegal because it's a loop parameter. The above causes us to
1833 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
1834 it on the Element entity, so we end up with an E_Variable node with the
1836 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
1837 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
1838 parameter not allowed" error if Is_Loop_Parameter.
1839 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
1840 trigger the call to Diagnose_Non_Variable_Lhs.

1845 * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of
1846 range values for System.Priority in CodePeer mode since the actual
1847 target compiler may provide a wider range.
1849 2018-05-30 Ed Schonberg <schonberg@adacore.com>
1851 * exp_unst.adb: Search specification of main unit as well, for
1854 2018-05-30 Ed Schonberg <schonberg@adacore.com>
1856 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
1857 a package body that is a compilation unit may contain blocks that
1858 declare local subprograms. In Subprogram_Unnesting Mode such
1859 subprograms must be handled as nested inside the (implicit) elaboration
1860 procedure that executes that statement part. To handle properly uplevel
1861 references we construct that subprogram explicitly, to contain blocks
1862 and inner subprograms, The statement part of the compilation unit
1863 becomes a call to this subprogram. This is only done if blocks are
1864 present in the statement list of the body.
1866 2018-05-30 Bob Duff <duff@adacore.com>

1876 for subprogram instantiations to enter callable entity into Subp table.

1883 package to account for the new secondary stack structure. Add types
1884 and subprograms for testing purposes. Add several documentation

1934 with a derivation of an untagged private type whose full view is a
1935 tagged type. In such case, collecting the list of primitives we may
1936 find two equality primitives: one associated with the untagged private

2139 * libgnat/s-casuti.ads, libgnat/s-casuti.adb (To_Upper, To_Lower,
2140 To_Mixed): New functions.
2141 * osint.adb: Cleanup: use Is_Directory_Separator, which correctly
2142 allows both '\' and '/' on Windows.

2170 * exp_unst.adb (Visit_Node): For indexed components and attribute
2171 references, examine index expressions or associated expressions as well
2172 to record uplevel references.
2173 (Vist_Node): For function and procedure calls, if a formal is an
2174 unconstrained array and the actual is constrained, check whether bounds
2175 of actual have uplevel references.
2177 2018-05-28 Ed Schonberg <schonberg@adacore.com>
2179 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
2180 they can appear as components of activation records.

2187 depends on a discriminant manually instead of using the predicate
2188 Size_Depends_On_Discriminant in the array type case.
2190 2018-05-28 Ed Schonberg <schonberg@adacore.com>
2192 * exp_unst.adb (Check_Static_Type): For a record subtype, check
2193 discriminant constraints as well.
2194 (Visit_Node): For a selected component, check type of prefix, as is
2195 done for indexed components and slices.
2197 2018-05-28 Javier Miranda <miranda@adacore.com>
2199 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
2200 value when converting a float value to a fixed-point value. This is
2201 required for CCG because it handles fixed-point types by means of
2202 unsigned integer type variables. The range check is now performed using
2203 the integer value stored in this temporary.
2205 2018-05-28 Yannick Moy <moy@adacore.com>
2207 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and

2218 (Inherited_Subprograms): Instance of Generic_Inherited_Subprograms with
2219 Sem_Disp.Find_Dispatching_Type.
2220 (Is_Overriding_Subprogram): Instance of
2221 Generic_Is_Overriding_Subprogram with Sem_Disp.Find_Dispatching_Type.

2223 with Sem_Disp.Find_Dispatching_Type.
2225 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
2227 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
2228 component type, do not expand array equality using the unconstrained
2229 base type, except for the case where the bounds of the type depend on a
2232 2018-05-28 Ed Schonberg <schonberg@adacore.com>
2234 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
2235 access-to-subprogram types, to indicate that an indirect call through
2236 such a type requires an activation record when compiling for LLVM.
2237 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
2239 2018-05-28 Ed Schonberg <schonberg@adacore.com>
2241 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
2242 when bounds of fixed type are static, to remove some spuerfluous
2243 implicit conversions and provide an accurate result when converting
2244 back and forth between the fixed point type and a floating point type.
2246 2018-05-28 Ed Schonberg <schonberg@adacore.com>
2248 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
2251 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
2253 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
2254 replaced, if any; all callers changed.
2255 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
2256 constant with private view so we take the address of that entity.
2257 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
2258 any; all callers changed. Handle N_Indexed_Component like
2259 N_Attribute_Reference. Add N_Type_Conversion case.
2260 (Visit_Node): Indexed references can be uplevel if the type isn't
2262 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
2263 been relocated, set first_named pointer in original node as well.
2265 2018-05-28 Ed Schonberg <schonberg@adacore.com>
2267 * exp_aggr.adb (Flatten): Copy tree of expression in a component
2268 association with a range or a set of discrete choices, rather than
2269 relocating the node. This avoids inconsistencies in the tree when
2270 handling nested subprograms with uplevel references for LLVM.

2274 * exp_util.adb (Possible_Bit_Aligned_Component): Always return False in

2283 * libgnat/a-convec.adb (Query_Element): Minor cleanup: remove an
2284 unnecessary use of 'Unrestricted_Access.
2286 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
2288 * repinfo.adb (Expr_Value_S): New routine.
2289 (List_Linker_Section): Properly extract the value of the section
2292 2018-05-28 Patrick Bernardi <bernardi@adacore.com>
2294 * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Update the
2295 description of the -D binder switch to reflect current usage.
2296 * gnat_ugn.texi: Regenerate.
2298 2018-05-28 Gary Dismukes <dismukes@adacore.com>

2313 used to determine how to generate an Init_Proc for a given type.
2314 (Needs_Constant_Address): Minor reformatting
2316 (Resolve_Null): Add logic to generate a conditional check in certain cases

2323 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
2325 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
2326 the declarations of single concurrent types because they fall in the
2327 category of full type and object declarations.
2329 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
2331 * repinfo.adb (Compute_Max_Length): Skip _Parent component.

2334 2018-05-28 Ed Schonberg <schonberg@adacore.com>
2336 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
2337 includes a call to function to which it applies. This may mean an
2338 omission of an attribute reference 'Result, in particular if the
2339 function is pqrameterless.
2341 2018-05-28 Justin Squirek <squirek@adacore.com>
2343 * sem_ch8.adb (Find_Expanded_Name): Add extra guard to make sure the
2344 misresolved package name is not a case of mistaken identity.
2346 2018-05-28 Yannick Moy <moy@adacore.com>
2348 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
2349 GNATprove mode, as the order of resolution (low then high) means that
2350 all the information is not available when resolving the low bound the
2353 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
2355 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
2356 end with the linker section, if any.
2357 (List_Entities): Do not output the linker section for record types,
2358 array types and variables.
2359 (Print_Expr): Factor out common processing for unary operators and
2360 special values. Adjust and reorder the various cases.
2361 (List_Object_Info): End with the linker section, if any.
2362 (List_Record_Info): Likewise.
2363 (List_Type_Info): Do not start with a blank line.
2365 2018-05-25 Nicolas Roche <roche@adacore.com>
2367 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
2368 that the result will be either -infinite or +infinite.
2370 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
2372 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,

2375 (Task_Storage_Size): Remove unused type.
2377 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2379 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
2380 of a fixed point type and the parent is a multiplying operation,
2381 resolve the operand with its own type because the context will impose a
2382 resulting type on the result of the multiplication by means of
2383 approriate conversion.
2385 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2387 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
2388 the in-place initialization aggregate created for pragmas
2389 Initialize_Scalars or Normalize_Scalars is performed with checks
2392 2018-05-25 Arnaud Charlet <charlet@adacore.com>
2394 * exp_aggr.adb (Convert_To_Positional): Bump default for
2395 Max_Others_Replicate to 32. Update comments.
2396 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
2397 (No_File_Info_Cache): Initialize separately.
2398 * osint.adb (No_File_Info_Cache): Update initializer.
2400 2018-05-25 Javier Miranda <miranda@adacore.com>
2402 * sem_res.adb (Resolve_Membership_Op): Allow the use of the membership
2403 test when the left operand is a class-wide interface and the right
2404 operand is not a class-wide type.
2405 * exp_ch4.adb (Tagged_Membership): Adding support for interface as the
2408 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2410 * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated
2411 in an others clause to prevent visibility issues with the generated
2413 (Component_OK_For_Backend): Return false for a quantified expression.
2414 (Check_Static_Component): Ditto.
2416 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2418 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
2419 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
2420 into three distring cases rather than in one loop which attempts to
2421 handle all three cases. This rewrite eliminates an issue where the last
2422 frame of the stack cannot be freed, thus causing the memory range of a
2423 new frame to approach the overflow point of the memory index type.
2424 Since the overflow is logically treated as a
2425 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
2426 (SS_Allocate_Static): New routine. The routine factorizes the static
2427 secondary stack-related code from the former SS_Allocate.
2429 2018-05-25 Sergey Rybin <rybin@adacore.com>
2431 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
2432 option for gnatelim.
2434 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2436 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
2437 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
2438 is created when the proper body of the stub is analyzed.
2439 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
2440 is the proper body of a subunit, the cloned body must be inserted in
2441 the declarative list that contains the stub.
2443 2018-05-25 Justin Squirek <squirek@adacore.com>
2445 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
2446 generate code for 6.5(8-10) so that we don't get an assertion error
2447 when dealing with an incomplete return type.
2449 2018-05-25 Arnaud Charlet <charlet@adacore.com>
2451 * pprint.adb (Expression_Name): Strip too long expressions to avoid
2452 carrying very large strings.
2454 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
2456 * switch-b.adb (Scan_Binder_Switches): binder switch -Q accepts Natural
2459 2018-05-25 Doug Rupp <rupp@adacore.com>

2478 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2480 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
2481 Validate_Derived_Type_Instance, to verify that all interfaces
2482 implemented by the formal type are also implemented by the actual. The
2483 verification is complicated when an interface of the formal is declared
2484 in a generic unit and the actual is declared in an instance of it.
2485 There is currently no mechanism to relate an interface declared within
2486 a generic to the corresponding interface in an instance, so we must
2487 traverse the list of interfaces of the actual, looking for a name
2488 match, and verifying that that interface is declared in an instance.
2490 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
2492 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
2493 assertions; replace function versions of Next_Formal/Next_Actual with
2494 their procedural versions (which are more concise).

2528 boolean type with convention C.
2529 * libgnat/i-cexten.ads (bool): Change to boolean with convention C.
2530 * gcc-interface/decl.c (gnat_to_gnu_entity): Add new local variable
2531 FOREIGN and use it throughout the function.
2532 <E_Enumeration_Type>: Set precision 1 on boolean types with foreign
2534 <E_Enumeration_Subtype>: Likewise for subtypes.
2535 <E_Record_Type>: Force the size of a storage unit on empty classes.
2536 * gcc-interface/utils.c (make_type_from_size) <BOOLEAN_TYPE>: Skip
2537 boolean types with precision 1 if the size is the expected one.

2554 * exp_unst.adb (Visit_Node): Restrict check for uplevel references in
2555 prefixes of array attributes, to prefixes that are entity names whose
2556 type is constrained.
2557 (Note_Uplevel_Bound): Verify that the bound is declared in an enclosing
2558 subprogram, as itype created for loops in pre/postcondition may appear
2559 in loops at the library level.
2561 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2563 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
2564 declaration is inserted into the tree and analyzed at that point, so
2565 should not be reinserted when the body is constructed. Inside a
2566 generic, ensure that the body is not inserted twice in the tree.

3601 * sem_prag.adb (Analyze_Pragma): Reimplement the handling of pragma
3602 Elaboration_Checks. The analysis now ensures that the pragma appears at
3603 the configuration level, and on the initial declaration of a unit.
3604 Other placements are either flagged as illegal, or ignored.

3724 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
3725 delegate the secondary stack management when there is no suitable
3726 transient context, and the transient scope was intended to manage the

3728 transient scope creation logic by special casing assignment statements
3729 of controlled components for type initialization procedures.

3731 the comment on usage.
3732 (Find_Transient_Context): Change the initinte loop into a while loop.

3734 contexts because they rely on special processing. Assignment statements
3735 are now treated as a normal transient context, special cases are
3736 handled by the caller. Add special processing for pragma Check.

3738 routine Find_Transient_Context.
3739 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly

3944 suitable construct to wrap, and the transient scope was intended to
3945 manage the secondary stack.
3946 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
3947 is a valid boundary for a transient expression which comes from the
3948 statements of the alternative, otherwise alternatives cannot be

3950 actions suppressed now stop the traversal as there is no point in
3951 looking for an enclosing construct. Add several N_xxx_Body choices to

3959 (Resolve_Actuals): Account for additional cases where finalization
3960 actions are required by utilizing predicate Needs_Finalization rather
3962 (Resolve_Call): Type initialization procedures can now utilize
3963 transient scopes to manage the secondary stack, thus preventing leaks
3964 during initialization. Remove the previous kludgy algorithm which
3965 attempts to manage the secondary stack at the object creation site.

4068 2018-01-11 Doug Rupp <rupp@adacore.com>
4070 * init.c (vxworks): Add macro checks for __aarch64__.
4072 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4074 * exp_util.adb (Add_Failure_Expression): New routine.
4075 (Make_Predicate_Check): Reimplement the handling of Predicate_Failure.
4076 * sem_util.adb (Is_Current_Instance): Code cleanup.
4078 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
4080 * libgnat/s-parame*.adb, libgnat/s-parame*.ads: Remove unneeded
4081 Default_Sec_Stack_Size.
4082 * libgnat/s-secsta.adb (SS_Allocate): Handle the fixed secondary stack
4083 limit check so that the integer index does not overflow. Check the
4084 dynamic stack allocation does not cause the secondary stack pointer to
4086 (SS_Info): Align colons.
4087 (SS_Init): Cover the case when bootstraping with an old compiler that
4088 does not set Default_SS_Size.
4090 2018-01-11 Ed Schonberg <schonberg@adacore.com>
4092 * sem_ch3.adb (Add_Internal_Interface_Entities): When checking the
4093 legality of an inherited operation that may require overriding, ignore
4094 primitive_wrappers that correspond to explicit operations that override
4095 an interface primitive.
4096 * exp_util.adb (Build_Class_Wide_Expression, Replace_Entity): If the
4097 operation to which the class-wide expression applies is a protected op.
4098 with a primitive_wrapper, verify that the updated inherited expression
4099 does not contain an internal call to a protected function. This
4100 completes the implementation of AI12-0166.
4102 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4104 * ali.adb: Document the remaining letters available for ALI lines.
4105 (Scan_ALI): A with clause is internal when it is encoded on a 'Z' line.
4106 * ali.ads: Update type With_Record. Field
4107 Implicit_With_From_Instantiation is no longer in use. Add field
4109 * csinfo.adb (CSinfo): Remove the setup for attribute
4110 Implicit_With_From_Instantiation.
4111 * lib-writ.adb (Collect_Withs): Correct the logic which marks a unit as
4112 either implicitly or explicitly withed.
4113 (Is_Implicit_With_Clause): New routine.
4114 (Write_ALI): Rename array Implicit_With to Has_Implicit_With to avoid
4115 confusion with the with clause attribute by the same name.
4116 (Write_With_Lines): Update the emission of 'W', 'Y', and 'Z' headers.
4117 * rtsfind.adb (Maybe_Add_With): Code cleanup.
4118 * sem_ch8.adb (Present_System_Aux): Code cleanup.
4119 * sem_ch10.adb (Expand_With_Clause): Mark the with clause as generated
4121 (Implicit_With_On_Parent): Mark the with clause as generated for a
4123 * sem_ch12.adb (Inherit_Context): With clauses inherited by an
4124 instantiation are no longer marked as Implicit_With_From_Instantiation
4125 because they are already marked as implicit.
4126 * sem_elab.adb (Ensure_Prior_Elaboration_Static): Remove the kludge
4127 which marks implicit with clauses as related to an instantiation.
4128 * sinfo.adb (Implicit_With_From_Instantiation): Removed.
4129 (Parent_With): New routine.
4130 (Set_Implicit_With_From_Instantiation): Removed.
4131 (Set_Parent_With): New routine.
4132 * sinfo.ads: Update the documentation of attribute Implicit_With.
4133 Remove attribute Implicit_With_From_Instantiation along with
4134 occurrences in nodes. Add attribute Parent_With along with occurrences
4136 (Implicit_With_From_Instantiation): Removed along with pragma Inline.
4137 (Parent_With): New routine along with pragma Inline.
4138 (Set_Implicit_With_From_Instantiation): Removed along with pragma Inline.
4139 (Set_Parent_With): New routine along with pragma Inline.
4141 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4143 * sem_util.adb (Find_Enclosing_Scope): Return the unique defining
4144 entity when the enclosing construct is a body.
4146 2018-01-11 Patrick Bernardi <bernardi@adacore.com>
4148 * exp_ch9.adb (Expand_N_Task_Type_Declaration): Simplified
4149 Secondary_Stack_Size handling as a pragma is now generated for the
4150 corresponding aspect instead of an attribute. Pragma expression is
4151 relocated instead of evaluated. Discriminant of the corresponding
4152 record type is referenced rather than the type discriminant.
4153 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
4154 Secondary_Stack_Size rep item checks to only look for the pragma rep.
4155 * sem_ch13.adb (Analyze_One_Aspect): Transform
4156 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
4157 because the attribute does not have visibility on a task type's
4158 discriminants when the type's definition is expanded.
4159 (Analyze_Attribute_Definition_Clause): Remove handling of
4160 Attribute_Secondary_Stack_Size.
4161 * snames.adb-tmpl, snames.ads-tmpl: Remove
4162 Attribute_Secondary_Stack_Size, no longer used.
4164 2018-01-11 Justin Squirek <squirek@adacore.com>
4166 * sem_ch8.adb: Minor comment fix.
4168 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4170 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
4171 individual action because the action may denote a complex expression,
4172 such as a case statement, which in turn may contain additional
4175 2018-01-11 Ed Schonberg <schonberg@adacore.com>
4177 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
4178 analysis on a copy of the expression with a copy of the index variable,
4179 because full expansion will rewrite construct into a loop with the
4180 original loop variable.
4181 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
4182 expression is an iterated component association. Full analysis takes
4183 place when construct is rewritten as a loop.
4184 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
4185 is not safe for in-place assignment.
4186 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
4187 entity with no homonym and no other entity in the scope.
4189 2018-01-11 Justin Squirek <squirek@adacore.com>
4191 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
4192 message to be printed on the pragma argument identifier.
4194 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4196 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
4197 entity of the generated invariant procedure in order to construct a
4198 proper entity chain.
4200 2018-01-11 Piotr Trojanek <trojanek@adacore.com>
4202 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
4205 2018-01-11 Arnaud Charlet <charlet@adacore.com>
4207 * einfo.ads, einfo.adb (Activation_Record_Component,
4208 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
4209 Allow E_Discriminant.
4211 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
4213 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
4214 for atomic access once the component size is taken into account and
4215 also do it if the component type is Atomic or Volatile_Full_Access.
4217 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
4219 * gnatvsn.ads: Bump copyright year.
4221 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
4222 Alan Hayward <alan.hayward@arm.com>
4223 David Sherwood <david.sherwood@arm.com>
4225 * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_BITSIZE
4228 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
4229 Alan Hayward <alan.hayward@arm.com>
4230 David Sherwood <david.sherwood@arm.com>
4232 * gcc-interface/misc.c (enumerate_modes): Treat GET_MODE_PRECISION

4236 Alan Hayward <alan.hayward@arm.com>
4237 David Sherwood <david.sherwood@arm.com>
4239 * gcc-interface/utils.c (gnat_types_compatible_p): Handle
4240 polynomial TYPE_VECTOR_SUBPARTS.
4242 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org>
4243 Alan Hayward <alan.hayward@arm.com>
4244 David Sherwood <david.sherwood@arm.com>
4246 * gcc-interface/misc.c (enumerate_modes): Handle polynomial
4249 2018-01-03 Jakub Jelinek <jakub@redhat.com>
4251 Update copyright years.
4253 * gnat_ugn.texi: Bump @copying's copyright year.
4254 * gnat_rm.texi: Likewise.
