3 * sem_ch13.adb (Get_Alignment_Value): Return 1 for Alignment 0,
4 and do not give an error.
5 * doc/gnat_rm/representation_clauses_and_pragmas.rst: Update the
6 corresponding documentation.
7 * gnat_rm.texi: Regenerate.
9 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
11 * inline.adb (Add_Pending_Instantiation): Fix off-by-one error
12 in the comparison against the maximum number of instantiations.
14 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
16 * inline.adb (Add_Pending_Instantiation): Use greater-or-equal
17 in the comparison against the maximum number of instantiations.
19 2019-08-14 Ed Schonberg <schonberg@adacore.com>
21 * sem_aux.adb (Next_Rep_Item): If a node in the rep chain
22 involves a Ghost aspect it may have been replaced by a null
23 statement; use the original node to find next Rep_Item.
24 * repinfo.adb (List_Entities): Do not list an Ignored
25 Ghost_Entity, for which information may have been deleted.
27 2019-08-14 Bob Duff <duff@adacore.com>
29 * sem_prag.ads, sem_prag.adb
30 (Process_Compile_Time_Warning_Or_Error): In parameterless
31 version, improve detection of whether we are in a generic unit
32 to cover the case of an instance within a generic unit.
33 (Process_Compile_Time_Warning_Or_Error): Rename the
34 two-parameter version to be
35 Validate_Compile_Time_Warning_Or_Error, and do not export it.
36 Issue a warning if the condition is not known at compile time.
37 The key point is that the warning must be given only for pragmas
38 deferred to the back end, because the back end discovers
39 additional values that are known at compile time. Previous
40 changes in this ticket have enabled this by deferring to the
41 back end without checking for special cases such as 'Size.
42 (Validate_Compile_Time_Warning_Or_Error): Rename to be
43 Defer_Compile_Time_Warning_Error_To_BE.
44 * warnsw.ads, warnsw.adb (Warn_On_Unknown_Compile_Time_Warning):
45 Add new switches -gnatw_c and -gnatw_C to control the above

54 the shortcut based on Is_Inlined to the back-end inlining case.
56 2019-08-14 Bob Duff <duff@adacore.com>
58 * inline.adb (Check_And_Split_Unconstrained_Function): Ignore
59 protected functions to get rid of spurious error. The
60 transformation done by this procedure triggers legality errors
61 in the generated code in this case.
63 2019-08-14 Bob Duff <duff@adacore.com>
65 * sem_prag.adb (Process_Compile_Time_Warning_Or_Error): Defer
66 processing to the back end in all cases where the pragma's
67 condition is not known at compile time during the front end
68 (except in generics), as opposed to detecting 'Size attributes
69 and the like. This ensures that we take advantage of whatever
70 can be compile-time known after running the back end, as opposed
71 to having the front end guess what the back end can do. Remove
72 a little duplicated code at the call site.
73 * gnat1drv.adb (Post_Compilation_Validation_Checks): Unlock the
74 Elists while in Validate_Compile_Time_Warning_Errors, because it
75 does analysis and name resolution, which sometimes involves

93 (Node_Table_Size): New constant.
94 (Node_Header_Num): New subtype.
95 (Node_Hash): New function.
96 (To_Pending_Instantiations): New hash table.
97 (Add_Inlined_Body): Bail out early for subprograms in the main
98 unit or subunit. Likewise if the Is_Called flag is set. If the
99 subprogram is an instance, invoke Add_Inlined_Instance. Call
100 Set_Is_Called earlier. If the subrogram is within an instance,
101 invoke Add_Inlined_Instance. Also deal with the case where the
102 call itself is within an instance.
103 (Add_Inlined_Instance): New procedure.
104 (Add_Inlined_Subprogram): Remove conditions always fulfilled.
105 (Add_Pending_Instantiation): Move the defence against ludicruous
106 number of instantiations to here. When back-end inlining is
107 enabled, associate an instantiation with its index in table and
108 mark a few selected kinds of instantiations as always needed.
109 (Initialize): Set Backend_Instances to No_Elist.
110 (Instantiate_Body): New procedure doing the work extracted
112 (Instantiate_Bodies): ...here. When back-end inlining is
113 enabled, loop over Called_Pending_Instantiations instead of
114 Pending_Instantiations.
115 (Is_Nested): Minor tweak.
116 (List_Inlining_Info): Also list the contents of
118 * sem_ch12.adb (Might_Inline_Subp): Return early if Is_Inlined
119 is set and otherwise set it before returning true.
120 (Analyze_Package_Instantiation): Remove the defence against
121 ludicruous number of instantiations. Invoke
122 Remove_Dead_Instance instead of doing the removal manually if
123 there is a guaranteed ABE.
125 2019-08-14 Gary Dismukes <dismukes@adacore.com>
127 * exp_ch3.adb (Predef_Spec_Or_Body): For an equality operation
128 of an interface type, create an expression function (that
129 returns False) rather than declaring an abstract function.
130 * freeze.adb (Check_Inherited_Conditions): Set Needs_Wrapper to
131 False unconditionally at the start of the loop creating wrappers
132 for inherited operations.
134 2019-08-14 Bob Duff <duff@adacore.com>
136 * table.adb: Assert that the table is not locked when increasing
137 Last, even if it doesn't cause reallocation. In other words,
138 assert that on operations that MIGHT cause reallocation.
139 * table.ads: Fix comment accordingly.
141 2019-08-14 Arnaud Charlet <charlet@adacore.com>
143 * doc/gnat_ugn/gnat_and_program_execution.rst: Remove
144 documentation of gnatelim.
146 2019-08-14 Bob Duff <duff@adacore.com>
148 * sem_prag.adb (Validate_Compile_Time_Warning_Error): Attach the
149 warning to the Sloc of the first pragma argument, rather than to
150 the pragma itself. This is to make pragmas processed after the
151 back end use the same Sloc as pragmas processed earlier, in the
152 front end. There's no reason for this discrepancy, and it
153 hinders further work on this ticket.
155 2019-08-14 Bob Duff <duff@adacore.com>
157 * sem.ads (Inside_A_Generic): Remove the ??? comment.
159 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>

170 * exp_aggr.adb (Init_Hidden_Discriminants): Avoid processing the
171 wrong discriminant, which could be of the wrong type.

231 2019-08-14 Ed Schonberg <schonberg@adacore.com>
233 * sem_util.adb (New_Copy_Tree, Visit_Entity): A quantified
234 expression includes the implicit declaration of the loop
235 parameter. When a quantified expression is copied during
236 expansion, for example when building the precondition code from
237 the generated pragma, a new loop parameter must be created for
238 the new tree, to prevent duplicate declarations for the same

322 * sem_res.adb (Resolve_Selected_Component): When the type of the
323 component is an access to a class-wide type and the type of the
324 context is an access to a tagged type the relevant type is that
325 of the component (since in such case we may need to generate
326 implicit type conversions or dispatching calls).

476 derivations that have interface components located at fixed
477 positions and interface components located at variable offset.
478 The offset of components located at fixed positions is computed
479 using the dummy object (similar to the case where all the
480 interface components are located at fixed positions).

852 'Valid as a replacement for a range check on a discrete type
853 when the bounds of the range are given by type conversions,
854 because in such a case there are distinct types involved and the

921 libgnat/s-valwch.ads: Change categorization of packages that
922 implement attribute 'Value from Pure to Preelaborate, to prevent
923 undesirable optimizations when the evaluation of the attribute

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

1124 analysis. Error messages for failed aliasing checks are only
1125 output in this case.
