11 (Analyze_Package_Instantiation): Use it to decide whether to add
12 a pending instantiation for the body of the package.
14 2019-08-19 Olivier Hainque <hainque@adacore.com>
16 * gcc-interface/trans.c (Acc_Loop_to_gnu): Return the openacc
17 BIND_EXPR node we have constructed on purpose. Remove unused

26 2019-08-14 Joffrey Huguet <huguet@adacore.com>
28 * libgnat/a-cofuba.ads: Add a Length attribute to type
29 Container. Add a type Array_Base which replaces the previous
30 Elements attribute of Container.
31 (Content_Init): New subprogram. It is used to initialize the
32 Base attribute of Container.
33 * libgnat/a-cofuba.adb (Resize): New subprogram. It is used to
34 resize the underlying array of a container if necessary.
35 (=, <=, Find, Get, Intersection, Length, Num_Overlaps, Set,
36 Union): Update to match changes in type declarations.
37 (Add): Modify body to damp the time and space cost in a specific
39 (Content_Init): New subprogram. It is used to initialize the
40 Base attribute of Container.
41 (Remove): Modify body to damp the time and space cost in a
44 2019-08-14 Bob Duff <duff@adacore.com>
46 * sem_ch13.adb (Get_Alignment_Value): Return 1 for Alignment 0,
47 and do not give an error.

49 corresponding documentation.
50 * gnat_rm.texi: Regenerate.
52 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
54 * inline.adb (Add_Pending_Instantiation): Fix off-by-one error
55 in the comparison against the maximum number of instantiations.
57 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
59 * inline.adb (Add_Pending_Instantiation): Use greater-or-equal
60 in the comparison against the maximum number of instantiations.
62 2019-08-14 Ed Schonberg <schonberg@adacore.com>
64 * sem_aux.adb (Next_Rep_Item): If a node in the rep chain
65 involves a Ghost aspect it may have been replaced by a null
66 statement; use the original node to find next Rep_Item.
67 * repinfo.adb (List_Entities): Do not list an Ignored
68 Ghost_Entity, for which information may have been deleted.
70 2019-08-14 Bob Duff <duff@adacore.com>
72 * sem_prag.ads, sem_prag.adb
73 (Process_Compile_Time_Warning_Or_Error): In parameterless
74 version, improve detection of whether we are in a generic unit
75 to cover the case of an instance within a generic unit.
76 (Process_Compile_Time_Warning_Or_Error): Rename the
77 two-parameter version to be
78 Validate_Compile_Time_Warning_Or_Error, and do not export it.
79 Issue a warning if the condition is not known at compile time.
80 The key point is that the warning must be given only for pragmas
81 deferred to the back end, because the back end discovers
82 additional values that are known at compile time. Previous
83 changes in this ticket have enabled this by deferring to the
84 back end without checking for special cases such as 'Size.
85 (Validate_Compile_Time_Warning_Or_Error): Rename to be
86 Defer_Compile_Time_Warning_Error_To_BE.
87 * warnsw.ads, warnsw.adb (Warn_On_Unknown_Compile_Time_Warning):
88 Add new switches -gnatw_c and -gnatw_C to control the above
90 * doc/gnat_ugn/building_executable_programs_with_gnat.rst:

99 2019-08-14 Bob Duff <duff@adacore.com>
101 * inline.adb (Check_And_Split_Unconstrained_Function): Ignore
102 protected functions to get rid of spurious error. The
103 transformation done by this procedure triggers legality errors
104 in the generated code in this case.
106 2019-08-14 Bob Duff <duff@adacore.com>
108 * sem_prag.adb (Process_Compile_Time_Warning_Or_Error): Defer
109 processing to the back end in all cases where the pragma's
110 condition is not known at compile time during the front end
111 (except in generics), as opposed to detecting 'Size attributes
112 and the like. This ensures that we take advantage of whatever
113 can be compile-time known after running the back end, as opposed
114 to having the front end guess what the back end can do. Remove
115 a little duplicated code at the call site.
116 * gnat1drv.adb (Post_Compilation_Validation_Checks): Unlock the
117 Elists while in Validate_Compile_Time_Warning_Errors, because it
118 does analysis and name resolution, which sometimes involves

135 (Called_Pending_Instantiations): New table.
136 (Node_Table_Size): New constant.
137 (Node_Header_Num): New subtype.
138 (Node_Hash): New function.
139 (To_Pending_Instantiations): New hash table.
140 (Add_Inlined_Body): Bail out early for subprograms in the main
141 unit or subunit. Likewise if the Is_Called flag is set. If the
142 subprogram is an instance, invoke Add_Inlined_Instance. Call
143 Set_Is_Called earlier. If the subrogram is within an instance,
144 invoke Add_Inlined_Instance. Also deal with the case where the
145 call itself is within an instance.
146 (Add_Inlined_Instance): New procedure.
147 (Add_Inlined_Subprogram): Remove conditions always fulfilled.
148 (Add_Pending_Instantiation): Move the defence against ludicruous
149 number of instantiations to here. When back-end inlining is
150 enabled, associate an instantiation with its index in table and
151 mark a few selected kinds of instantiations as always needed.
152 (Initialize): Set Backend_Instances to No_Elist.
153 (Instantiate_Body): New procedure doing the work extracted
155 (Instantiate_Bodies): ...here. When back-end inlining is
156 enabled, loop over Called_Pending_Instantiations instead of
157 Pending_Instantiations.
158 (Is_Nested): Minor tweak.
159 (List_Inlining_Info): Also list the contents of
161 * sem_ch12.adb (Might_Inline_Subp): Return early if Is_Inlined
162 is set and otherwise set it before returning true.
163 (Analyze_Package_Instantiation): Remove the defence against
164 ludicruous number of instantiations. Invoke
165 Remove_Dead_Instance instead of doing the removal manually if
166 there is a guaranteed ABE.
168 2019-08-14 Gary Dismukes <dismukes@adacore.com>
170 * exp_ch3.adb (Predef_Spec_Or_Body): For an equality operation
171 of an interface type, create an expression function (that
172 returns False) rather than declaring an abstract function.
173 * freeze.adb (Check_Inherited_Conditions): Set Needs_Wrapper to
174 False unconditionally at the start of the loop creating wrappers
175 for inherited operations.
177 2019-08-14 Bob Duff <duff@adacore.com>
179 * table.adb: Assert that the table is not locked when increasing
180 Last, even if it doesn't cause reallocation. In other words,
181 assert that on operations that MIGHT cause reallocation.
182 * table.ads: Fix comment accordingly.
184 2019-08-14 Arnaud Charlet <charlet@adacore.com>
186 * doc/gnat_ugn/gnat_and_program_execution.rst: Remove
187 documentation of gnatelim.
189 2019-08-14 Bob Duff <duff@adacore.com>
191 * sem_prag.adb (Validate_Compile_Time_Warning_Error): Attach the
192 warning to the Sloc of the first pragma argument, rather than to
193 the pragma itself. This is to make pragmas processed after the
194 back end use the same Sloc as pragmas processed earlier, in the
195 front end. There's no reason for this discrepancy, and it
196 hinders further work on this ticket.
198 2019-08-14 Bob Duff <duff@adacore.com>
200 * sem.ads (Inside_A_Generic): Remove the ??? comment.
202 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>

211 2019-08-14 Bob Duff <duff@adacore.com>
213 * exp_aggr.adb (Init_Hidden_Discriminants): Avoid processing the
214 wrong discriminant, which could be of the wrong type.

272 arrays with bounds not known at compile time.
274 2019-08-14 Ed Schonberg <schonberg@adacore.com>
276 * sem_util.adb (New_Copy_Tree, Visit_Entity): A quantified
277 expression includes the implicit declaration of the loop
278 parameter. When a quantified expression is copied during
279 expansion, for example when building the precondition code from
280 the generated pragma, a new loop parameter must be created for
281 the new tree, to prevent duplicate declarations for the same

366 component is an access to a class-wide type and the type of the
367 context is an access to a tagged type the relevant type is that

373 * exp_aggr.adb (Aggr_Assignment_OK_For_Backend): Preanalyze

518 * exp_disp.adb (Make_Secondary_DT): Handle record type
519 derivations that have interface components located at fixed
520 positions and interface components located at variable offset.
521 The offset of components located at fixed positions is computed
522 using the dummy object (similar to the case where all the
523 interface components are located at fixed positions).
524 (Make_DT): Build the dummy object for all tagged types that
525 implement interface types (that is, build it also for types with

896 when the bounds of the range are given by type conversions,

964 libgnat/s-valwch.ads: Change categorization of packages that
965 implement attribute 'Value from Pure to Preelaborate, to prevent
966 undesirable optimizations when the evaluation of the attribute
967 raises Constraint_Error, but subsequent use of the result of

990 result of this enhancement, the internal tables declared using
991 Index_Table have a length closer to the real needs, thus
