31 * sem_ch6.adb (Analyze_Subprogram_Body_Helper, Mask_Type):
32 Refine the handling of freezing types for expression functions
33 that are not completions, when analyzing the generated body for

66 abstract progenitor operation requires subtype conformance;
67 requiring equality of return types in the case of a function is
68 too restrictive and leads to spurious errors when the return
69 type is a generic actual.

125 Perm_Error if there is any mismatch.
126 (Return_Declarations, Return_Globals, Return_The_Global): Check
127 the state of a given name at the end of the subprogram. These
128 procedures may change depending on how we shall finally deal
129 with globals and the rhs state in a move operation.
130 (Set_Perm_Extensions, Set_Perm_Prefixes_Borrow,
131 Set_Perm_Prefixes, Setup_Globals, Setup_Parameter_Or_Global,

637 outside of a subprogram body. This case was previously handled during
638 preanalysis; the frozen entities were remembered and left pending until
639 we continued freezeing entities outside of the subprogram. Now, when
640 climbing the parents chain to locate the correct placement for the
641 freezeing node, we check if the entity can be frozen and only when no

655 with an additional parameter which is used to specify if during
656 preanalysis we are allowed to freeze entities. If the new parameter is
657 True then the subtree root node is marked as Must_Not_Freeze and no
658 entities are frozen during preanalysis.
659 (Preanalyze_And_Resolve): Invokes the internal version of
660 Preanalyze_And_Resolve without entity freezing.

1585 expansion involves a modular index type of an array type, and the index
1586 type is not immediately visible.

1596 if the local raise statement includes a string expression. This
1597 expression might be picked up by an outer handler or discarded, but
1598 plays no role in this transformation.

1649 (Start_Search): Modify to use Start_Search_Internal
1650 (Start_Search_Internal): Add to break out an extra flag for searching
1651 case insensative due to the potential for directories within the same

1723 comment about the memset case.
1725 2018-05-30 Bob Duff <duff@adacore.com>
1727 * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
1728 to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
1729 We need to analyze it as part of analyzing the block, so that if the
1730 call to Element that initializes Elmt_Decl returns on the secondary
1731 stack, the block will ss_mark/ss_release. This block is inside the
1732 loop; we don't want to leak memory until the loop exits. The purpose
1733 of analyzing Elmt_Decl first was to catch the error of modifying it,
1734 which is illegal because it's a loop parameter. The above causes us to
1735 miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
1736 it on the Element entity, so we end up with an E_Variable node with the
1738 * einfo.ads, einfo.adb (Is_Loop_Parameter): New flag.
1739 * sem_ch5.adb (Diagnose_Non_Variable_Lhs): Give the "assignment to loop
1740 parameter not allowed" error if Is_Loop_Parameter.
1741 * sem_util.adb (Is_Variable): Return False if Is_Loop_Parameter, to
1742 trigger the call to Diagnose_Non_Variable_Lhs.
1744 2018-05-30 Arnaud Charlet <charlet@adacore.com>

1747 * sem_eval.adb (Check_Non_Static_Context, Out_Of_Range): Ignore out of
1748 range values for System.Priority in CodePeer mode since the actual
1749 target compiler may provide a wider range.

1753 * exp_unst.adb: Search specification of main unit as well, for
1756 2018-05-30 Ed Schonberg <schonberg@adacore.com>
1758 * exp_ch7.adb (Check_Unnesting_Elaboration_Code): The statement part of
1759 a package body that is a compilation unit may contain blocks that
1760 declare local subprograms. In Subprogram_Unnesting Mode such
1761 subprograms must be handled as nested inside the (implicit) elaboration
1762 procedure that executes that statement part. To handle properly uplevel
1763 references we construct that subprogram explicitly, to contain blocks
1764 and inner subprograms, The statement part of the compilation unit
1765 becomes a call to this subprogram. This is only done if blocks are
1766 present in the statement list of the body.
1768 2018-05-30 Bob Duff <duff@adacore.com>
1770 * exp_ch7.adb: Minor comment fix.

1778 for subprogram instantiations to enter callable entity into Subp table.

1785 package to account for the new secondary stack structure. Add types
1786 and subprograms for testing purposes. Add several documentation

1835 (Collect_Primitive_Operations): Handle untagged private types completed
1836 with a derivation of an untagged private type whose full view is a
1837 tagged type. In such case, collecting the list of primitives we may
1838 find two equality primitives: one associated with the untagged private
1839 and another associated with the ultimate tagged type (and we must
1840 remove from the returned list this latter one).

2070 2018-05-28 Ed Schonberg <schonberg@adacore.com>
2072 * exp_unst.adb (Visit_Node): For indexed components and attribute
2073 references, examine index expressions or associated expressions as well
2074 to record uplevel references.
2075 (Vist_Node): For function and procedure calls, if a formal is an
2076 unconstrained array and the actual is constrained, check whether bounds
2077 of actual have uplevel references.
2079 2018-05-28 Ed Schonberg <schonberg@adacore.com>
2081 * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus
2082 they can appear as components of activation records.
2083 * exp_unst.adb (Visit_Node): A reference to an exception may be an
2086 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
2088 * exp_ch4.adb (Expand_Composite_Equality): Compute whether the size
2089 depends on a discriminant manually instead of using the predicate
2090 Size_Depends_On_Discriminant in the array type case.
2092 2018-05-28 Ed Schonberg <schonberg@adacore.com>
2094 * exp_unst.adb (Check_Static_Type): For a record subtype, check
2095 discriminant constraints as well.
2096 (Visit_Node): For a selected component, check type of prefix, as is
2097 done for indexed components and slices.
2099 2018-05-28 Javier Miranda <miranda@adacore.com>
2101 * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer
2102 value when converting a float value to a fixed-point value. This is
2103 required for CCG because it handles fixed-point types by means of
2104 unsigned integer type variables. The range check is now performed using
2105 the integer value stored in this temporary.
2107 2018-05-28 Yannick Moy <moy@adacore.com>
2109 * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and

2119 Is_Overriding_Subprogram, generic in Find_Dispatching_Type function.
2120 (Inherited_Subprograms): Instance of Generic_Inherited_Subprograms with
2121 Sem_Disp.Find_Dispatching_Type.
2122 (Is_Overriding_Subprogram): Instance of
2123 Generic_Is_Overriding_Subprogram with Sem_Disp.Find_Dispatching_Type.
2124 (Inheritance_Utilities_Inst): Instance of Inheritance_Utilities
2125 with Sem_Disp.Find_Dispatching_Type.
2127 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
2129 * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP)
2130 component type, do not expand array equality using the unconstrained
2131 base type, except for the case where the bounds of the type depend on a
2134 2018-05-28 Ed Schonberg <schonberg@adacore.com>
2136 * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on
2137 access-to-subprogram types, to indicate that an indirect call through
2138 such a type requires an activation record when compiling for LLVM.
2139 * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed.
2141 2018-05-28 Ed Schonberg <schonberg@adacore.com>
2143 * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions
2144 when bounds of fixed type are static, to remove some spuerfluous
2145 implicit conversions and provide an accurate result when converting
2146 back and forth between the fixed point type and a floating point type.
2148 2018-05-28 Ed Schonberg <schonberg@adacore.com>
2150 * exp_unst.adb (Unnest_Subprogram): Prevent creation of empty
2153 2018-05-28 Richard Kenner <kenner@vlsi1.ultra.nyu.edu>
2155 * exp_unst.adb (Check_Static_Type): Add argument to indicate node to be
2156 replaced, if any; all callers changed.
2157 (Note_Uplevel_Ref): Likewise. Also replace reference to deferred
2158 constant with private view so we take the address of that entity.
2159 (Note_Uplevel_Bound): Add argument to indicate node to be replaced, if
2160 any; all callers changed. Handle N_Indexed_Component like
2161 N_Attribute_Reference. Add N_Type_Conversion case.
2162 (Visit_Node): Indexed references can be uplevel if the type isn't
2164 (Unnest_Subprograms): Don't rewrite if no reference given. If call has
2165 been relocated, set first_named pointer in original node as well.
2167 2018-05-28 Ed Schonberg <schonberg@adacore.com>
2169 * exp_aggr.adb (Flatten): Copy tree of expression in a component
2170 association with a range or a set of discrete choices, rather than
2171 relocating the node. This avoids inconsistencies in the tree when
2172 handling nested subprograms with uplevel references for LLVM.
2174 2018-05-28 Arnaud Charlet <charlet@adacore.com>
2176 * exp_util.adb (Possible_Bit_Aligned_Component): Always return False in

2185 * libgnat/a-convec.adb (Query_Element): Minor cleanup: remove an
2186 unnecessary use of 'Unrestricted_Access.
2188 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
2190 * repinfo.adb (Expr_Value_S): New routine.
2191 (List_Linker_Section): Properly extract the value of the section
2194 2018-05-28 Patrick Bernardi <bernardi@adacore.com>
2196 * doc/gnat_ugn/building_executable_programs_with_gnat.rst: Update the
2197 description of the -D binder switch to reflect current usage.
2198 * gnat_ugn.texi: Regenerate.
2200 2018-05-28 Gary Dismukes <dismukes@adacore.com>
2202 * exp_ch3.adb: Minor reformatting

2225 2018-05-28 Hristian Kirtchev <kirtchev@adacore.com>
2227 * sem_prag.adb (Process_Atomic_Independent_Shared_Volatile): Include
2228 the declarations of single concurrent types because they fall in the
2229 category of full type and object declarations.
2231 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
2233 * repinfo.adb (Compute_Max_Length): Skip _Parent component.

2236 2018-05-28 Ed Schonberg <schonberg@adacore.com>
2238 * sem_util.adb (Is_Function_Result): Add a warning if a postcondition
2239 includes a call to function to which it applies. This may mean an
2240 omission of an attribute reference 'Result, in particular if the
2241 function is pqrameterless.
2243 2018-05-28 Justin Squirek <squirek@adacore.com>
2245 * sem_ch8.adb (Find_Expanded_Name): Add extra guard to make sure the

2250 * sem_res.adb (Resolve_Range): Re-resolve the low bound of a range in
2251 GNATprove mode, as the order of resolution (low then high) means that

2255 2018-05-28 Eric Botcazou <ebotcazou@adacore.com>
2257 * repinfo.adb (List_Array_Info): Start with an explicit blank line and
2258 end with the linker section, if any.
2259 (List_Entities): Do not output the linker section for record types,
2260 array types and variables.
2261 (Print_Expr): Factor out common processing for unary operators and
2262 special values. Adjust and reorder the various cases.
2263 (List_Object_Info): End with the linker section, if any.
2264 (List_Record_Info): Likewise.
2265 (List_Type_Info): Do not start with a blank line.
2267 2018-05-25 Nicolas Roche <roche@adacore.com>
2269 * libgnat/s-valrea.adb (Scan_Real): Abort computation once it is sure
2270 that the result will be either -infinite or +infinite.
2272 2018-05-25 Patrick Bernardi <bernardi@adacore.com>
2274 * libgnat/s-parame.ads, libgnat/s-parame__vxworks.ads,

2277 (Task_Storage_Size): Remove unused type.
2279 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2281 * sem_res.adb (Set_Mixed_Mode_Operand): If the operand is an expression
2282 of a fixed point type and the parent is a multiplying operation,
2283 resolve the operand with its own type because the context will impose a
2284 resulting type on the result of the multiplication by means of
2285 approriate conversion.
2287 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2289 * exp_ch3.adb (Default_Initialize_Object): Ensure that the analysis of
2290 the in-place initialization aggregate created for pragmas
2291 Initialize_Scalars or Normalize_Scalars is performed with checks
2294 2018-05-25 Arnaud Charlet <charlet@adacore.com>
2296 * exp_aggr.adb (Convert_To_Positional): Bump default for
2297 Max_Others_Replicate to 32. Update comments.
2298 * osint.ads (Unknown_Attributes): No longer pretend this is a constant.
2299 (No_File_Info_Cache): Initialize separately.

2304 * sem_res.adb (Resolve_Membership_Op): Allow the use of the membership
2305 test when the left operand is a class-wide interface and the right
2306 operand is not a class-wide type.
2307 * exp_ch4.adb (Tagged_Membership): Adding support for interface as the
2310 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2312 * exp_aggr.adb (Flatten): A quantified expression cannot be duplicated
2313 in an others clause to prevent visibility issues with the generated

2318 2018-05-25 Hristian Kirtchev <kirtchev@adacore.com>
2320 * libgnat/s-secsta.adb (SS_Allocate): Reimplemented.
2321 (SS_Allocate_Dynamic): New routine. The allocation logic is now split
2322 into three distring cases rather than in one loop which attempts to
2323 handle all three cases. This rewrite eliminates an issue where the last
2324 frame of the stack cannot be freed, thus causing the memory range of a
2325 new frame to approach the overflow point of the memory index type.
2326 Since the overflow is logically treated as a
2327 too-much-memory-on-the-stack scenario, it causes a bogus Storage_Error.
2328 (SS_Allocate_Static): New routine. The routine factorizes the static
2329 secondary stack-related code from the former SS_Allocate.
2331 2018-05-25 Sergey Rybin <rybin@adacore.com>
2333 * doc/gnat_ugn/gnat_and_program_execution.rst: Add description of '-U'
2334 option for gnatelim.
2336 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2338 * sem_ch6.adb (Analyze_Subprogram_Body_Helper): Do not create
2339 Class_Wide_Clone_Body when analyzing a subprogram_body_stub: the clone
2340 is created when the proper body of the stub is analyzed.
2341 * sem_util.adb (ZBuild_Class_Wide_Clone_Body): If the subprogram body
2342 is the proper body of a subunit, the cloned body must be inserted in
2343 the declarative list that contains the stub.
2345 2018-05-25 Justin Squirek <squirek@adacore.com>
2347 * exp_ch6.adb (Expand_Simple_Function_Return): Add guard in check to
2348 generate code for 6.5(8-10) so that we don't get an assertion error
2349 when dealing with an incomplete return type.
2351 2018-05-25 Arnaud Charlet <charlet@adacore.com>
2353 * pprint.adb (Expression_Name): Strip too long expressions to avoid
2354 carrying very large strings.

2380 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2382 * sem_ch12.adb (Instance_Exists): New function, subsidiary of
2383 Validate_Derived_Type_Instance, to verify that all interfaces
2384 implemented by the formal type are also implemented by the actual. The
2385 verification is complicated when an interface of the formal is declared
2386 in a generic unit and the actual is declared in an instance of it.
2387 There is currently no mechanism to relate an interface declared within
2388 a generic to the corresponding interface in an instance, so we must
2389 traverse the list of interfaces of the actual, looking for a name
2390 match, and verifying that that interface is declared in an instance.
2392 2018-05-25 Piotr Trojanek <trojanek@adacore.com>
2394 * sem_util.adb (Iterate_Call_Parameters): Rewrite with extra
2395 assertions; replace function versions of Next_Formal/Next_Actual with
2396 their procedural versions (which are more concise).

2407 for incremental looping. Remove references to Rel_Time and
2408 Relative_Timed_Wait.
2409 * libgnat/s-osprim__posix.adb, libgnat/s-osprim__posix2008.adb

2430 boolean type with convention C.
2431 * libgnat/i-cexten.ads (bool): Change to boolean with convention C.
2432 * gcc-interface/decl.c (gnat_to_gnu_entity): Add new local variable
2433 FOREIGN and use it throughout the function.
2434 <E_Enumeration_Type>: Set precision 1 on boolean types with foreign
2436 <E_Enumeration_Subtype>: Likewise for subtypes.
2437 <E_Record_Type>: Force the size of a storage unit on empty classes.
2438 * gcc-interface/utils.c (make_type_from_size) <BOOLEAN_TYPE>: Skip
2439 boolean types with precision 1 if the size is the expected one.

2457 prefixes of array attributes, to prefixes that are entity names whose
2458 type is constrained.
2459 (Note_Uplevel_Bound): Verify that the bound is declared in an enclosing
2460 subprogram, as itype created for loops in pre/postcondition may appear
2461 in loops at the library level.
2463 2018-05-25 Ed Schonberg <schonberg@adacore.com>
2465 * sem_ch13.adb (Build_Predicate_Functions): The predicate function
2466 declaration is inserted into the tree and analyzed at that point, so
2467 should not be reinserted when the body is constructed. Inside a
2468 generic, ensure that the body is not inserted twice in the tree.
2470 2018-05-25 Yannick Moy <moy@adacore.com>

2503 2018-05-24 Javier Miranda <miranda@adacore.com>
2505 * exp_ch8.adb (Build_Body_For_Renaming): Adding support to build the

2547 * sem_ch8.adb (Analyze_Use_Type): Do not assign the Prev_Use_Clause
2548 link to a use_type clause if this would cause an infinite loop in the

3563 Address, and type of Low, High to Storage_Offset.
3564 (Low): Rename as Low_Address and convey that the return value is a
3565 runtime reference accounting for a load address.

3624 2018-05-21 Hristian Kirtchev <kirtchev@adacore.com>
3626 * exp_ch7.adb (Establish_Transient_Scope): Code cleanup. Do not
3627 delegate the secondary stack management when there is no suitable
3628 transient context, and the transient scope was intended to manage the
3629 secondary stack because this causes premature reclamation. Change the
3630 transient scope creation logic by special casing assignment statements
3631 of controlled components for type initialization procedures.

3633 the comment on usage.
3634 (Find_Transient_Context): Change the initinte loop into a while loop.

3636 contexts because they rely on special processing. Assignment statements
3637 are now treated as a normal transient context, special cases are
3638 handled by the caller. Add special processing for pragma Check.
3639 (Is_OK_Construct): Removed. Its functionality has been merged in
3640 routine Find_Transient_Context.
3641 * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly
3642 retrieve the subprogram being invoked. Use a more accurate predicate
3643 (Requires_Transient_Scope) to determine that the function will emply
3644 the secondary stack.

3846 suitable construct to wrap, and the transient scope was intended to
3847 manage the secondary stack.
3848 (Find_Node_To_Be_Wrapped): Restructured. A case_statement_alternative
3849 is a valid boundary for a transient expression which comes from the
3850 statements of the alternative, otherwise alternatives cannot be
3851 wrapped. Assignments of controlled objects which have controlled
3852 actions suppressed now stop the traversal as there is no point in
3853 looking for an enclosing construct. Add several N_xxx_Body choices to
3854 the termination conditions for completeness.

3861 (Resolve_Actuals): Account for additional cases where finalization
3862 actions are required by utilizing predicate Needs_Finalization rather
3864 (Resolve_Call): Type initialization procedures can now utilize
3865 transient scopes to manage the secondary stack, thus preventing leaks
3866 during initialization. Remove the previous kludgy algorithm which
3867 attempts to manage the secondary stack at the object creation site.

3915 in the generic unless they reference a formal subprogram. Clarify

4053 relocated instead of evaluated. Discriminant of the corresponding
4054 record type is referenced rather than the type discriminant.
4055 (Create_Secondary_Stack_For_Task, Make_Task_Create_Call): Update
4056 Secondary_Stack_Size rep item checks to only look for the pragma rep.
4057 * sem_ch13.adb (Analyze_One_Aspect): Transform
4058 Aspect_Secondary_Stack_Size into a pragma instead of an attribute
4059 because the attribute does not have visibility on a task type's
4060 discriminants when the type's definition is expanded.
4061 (Analyze_Attribute_Definition_Clause): Remove handling of
4062 Attribute_Secondary_Stack_Size.
4063 * snames.adb-tmpl, snames.ads-tmpl: Remove
4064 Attribute_Secondary_Stack_Size, no longer used.

4068 * sem_ch8.adb: Minor comment fix.
4070 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4072 * exp_ch4.adb (Process_Action): Do not abandon the inspection of an
4073 individual action because the action may denote a complex expression,
4074 such as a case statement, which in turn may contain additional
4077 2018-01-11 Ed Schonberg <schonberg@adacore.com>
4079 * sem_aggr.adb (Resolve_Iterated_Component_Association): Perform
4080 analysis on a copy of the expression with a copy of the index variable,
4081 because full expansion will rewrite construct into a loop with the
4082 original loop variable.
4083 * exp_aggr.adb (Gen_Assign): Defer analysis and resolution if the
4084 expression is an iterated component association. Full analysis takes
4085 place when construct is rewritten as a loop.
4086 (In_Place_Assign_OK, Safe_Component): An iterated_component_association
4087 is not safe for in-place assignment.
4088 * sem_util.adb (Remove_Entity): Handle properly the case of an isolated
4089 entity with no homonym and no other entity in the scope.
4091 2018-01-11 Justin Squirek <squirek@adacore.com>
4093 * sem_prag.adb (Analyze_Pragma:Pragma_Loop_Variant): Modify error
4094 message to be printed on the pragma argument identifier.
4096 2018-01-11 Hristian Kirtchev <kirtchev@adacore.com>
4098 * exp_util.adb (Build_Invariant_Procedure_Declaration): Set the last
4099 entity of the generated invariant procedure in order to construct a
4100 proper entity chain.

4104 * sem_ch13.adb (Build_Predicate_Functions): Fix minor issues in
4107 2018-01-11 Arnaud Charlet <charlet@adacore.com>
4109 * einfo.ads, einfo.adb (Activation_Record_Component,
4110 Set_Activation_Record_Component, Set_Is_Uplevel_Referenced_Entity):
4111 Allow E_Discriminant.
4113 2018-01-10 Eric Botcazou <ebotcazou@adacore.com>
4115 * gcc-interface/decl.c (gnat_to_gnu_component_type): Apply the check
4116 for atomic access once the component size is taken into account and
4117 also do it if the component type is Atomic or Volatile_Full_Access.
4119 2018-01-04 Eric Botcazou <ebotcazou@adacore.com>
4121 * gnatvsn.ads: Bump copyright year.
