21 2019-08-14 Joffrey Huguet <huguet@adacore.com>
23 * libgnat/a-cofuba.ads: Add a Length attribute to type
24 Container. Add a type Array_Base which replaces the previous
25 Elements attribute of Container.
26 (Content_Init): New subprogram. It is used to initialize the
27 Base attribute of Container.
28 * libgnat/a-cofuba.adb (Resize): New subprogram. It is used to
29 resize the underlying array of a container if necessary.
30 (=, <=, Find, Get, Intersection, Length, Num_Overlaps, Set,
31 Union): Update to match changes in type declarations.
32 (Add): Modify body to damp the time and space cost in a specific

44 corresponding documentation.
45 * gnat_rm.texi: Regenerate.
47 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
49 * inline.adb (Add_Pending_Instantiation): Fix off-by-one error
50 in the comparison against the maximum number of instantiations.
52 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>
54 * inline.adb (Add_Pending_Instantiation): Use greater-or-equal
55 in the comparison against the maximum number of instantiations.
57 2019-08-14 Ed Schonberg <schonberg@adacore.com>
59 * sem_aux.adb (Next_Rep_Item): If a node in the rep chain
60 involves a Ghost aspect it may have been replaced by a null
61 statement; use the original node to find next Rep_Item.
62 * repinfo.adb (List_Entities): Do not list an Ignored
63 Ghost_Entity, for which information may have been deleted.
65 2019-08-14 Bob Duff <duff@adacore.com>
67 * sem_prag.ads, sem_prag.adb
68 (Process_Compile_Time_Warning_Or_Error): In parameterless
69 version, improve detection of whether we are in a generic unit
70 to cover the case of an instance within a generic unit.
71 (Process_Compile_Time_Warning_Or_Error): Rename the
72 two-parameter version to be
73 Validate_Compile_Time_Warning_Or_Error, and do not export it.
74 Issue a warning if the condition is not known at compile time.
75 The key point is that the warning must be given only for pragmas
76 deferred to the back end, because the back end discovers
77 additional values that are known at compile time. Previous
78 changes in this ticket have enabled this by deferring to the
79 back end without checking for special cases such as 'Size.
80 (Validate_Compile_Time_Warning_Or_Error): Rename to be
81 Defer_Compile_Time_Warning_Error_To_BE.
82 * warnsw.ads, warnsw.adb (Warn_On_Unknown_Compile_Time_Warning):

94 2019-08-14 Bob Duff <duff@adacore.com>
96 * inline.adb (Check_And_Split_Unconstrained_Function): Ignore
97 protected functions to get rid of spurious error. The
98 transformation done by this procedure triggers legality errors
99 in the generated code in this case.
101 2019-08-14 Bob Duff <duff@adacore.com>
103 * sem_prag.adb (Process_Compile_Time_Warning_Or_Error): Defer
104 processing to the back end in all cases where the pragma's
105 condition is not known at compile time during the front end
106 (except in generics), as opposed to detecting 'Size attributes
107 and the like. This ensures that we take advantage of whatever
108 can be compile-time known after running the back end, as opposed
109 to having the front end guess what the back end can do. Remove
110 a little duplicated code at the call site.
111 * gnat1drv.adb (Post_Compilation_Validation_Checks): Unlock the
112 Elists while in Validate_Compile_Time_Warning_Errors, because it
113 does analysis and name resolution, which sometimes involves

131 (Node_Table_Size): New constant.
132 (Node_Header_Num): New subtype.
133 (Node_Hash): New function.
134 (To_Pending_Instantiations): New hash table.
135 (Add_Inlined_Body): Bail out early for subprograms in the main
136 unit or subunit. Likewise if the Is_Called flag is set. If the
137 subprogram is an instance, invoke Add_Inlined_Instance. Call
138 Set_Is_Called earlier. If the subrogram is within an instance,
139 invoke Add_Inlined_Instance. Also deal with the case where the
140 call itself is within an instance.
141 (Add_Inlined_Instance): New procedure.
142 (Add_Inlined_Subprogram): Remove conditions always fulfilled.
143 (Add_Pending_Instantiation): Move the defence against ludicruous
144 number of instantiations to here. When back-end inlining is
145 enabled, associate an instantiation with its index in table and
146 mark a few selected kinds of instantiations as always needed.
147 (Initialize): Set Backend_Instances to No_Elist.
148 (Instantiate_Body): New procedure doing the work extracted
150 (Instantiate_Bodies): ...here. When back-end inlining is
151 enabled, loop over Called_Pending_Instantiations instead of
152 Pending_Instantiations.
153 (Is_Nested): Minor tweak.
154 (List_Inlining_Info): Also list the contents of
156 * sem_ch12.adb (Might_Inline_Subp): Return early if Is_Inlined
157 is set and otherwise set it before returning true.
158 (Analyze_Package_Instantiation): Remove the defence against
159 ludicruous number of instantiations. Invoke
160 Remove_Dead_Instance instead of doing the removal manually if
161 there is a guaranteed ABE.
163 2019-08-14 Gary Dismukes <dismukes@adacore.com>
165 * exp_ch3.adb (Predef_Spec_Or_Body): For an equality operation
166 of an interface type, create an expression function (that
167 returns False) rather than declaring an abstract function.
168 * freeze.adb (Check_Inherited_Conditions): Set Needs_Wrapper to
169 False unconditionally at the start of the loop creating wrappers
170 for inherited operations.
172 2019-08-14 Bob Duff <duff@adacore.com>
174 * table.adb: Assert that the table is not locked when increasing
175 Last, even if it doesn't cause reallocation. In other words,

181 * doc/gnat_ugn/gnat_and_program_execution.rst: Remove
182 documentation of gnatelim.
184 2019-08-14 Bob Duff <duff@adacore.com>
186 * sem_prag.adb (Validate_Compile_Time_Warning_Error): Attach the
187 warning to the Sloc of the first pragma argument, rather than to
188 the pragma itself. This is to make pragmas processed after the
189 back end use the same Sloc as pragmas processed earlier, in the
190 front end. There's no reason for this discrepancy, and it
191 hinders further work on this ticket.
193 2019-08-14 Bob Duff <duff@adacore.com>
195 * sem.ads (Inside_A_Generic): Remove the ??? comment.
197 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>

269 2019-08-14 Ed Schonberg <schonberg@adacore.com>
271 * sem_util.adb (New_Copy_Tree, Visit_Entity): A quantified
272 expression includes the implicit declaration of the loop
273 parameter. When a quantified expression is copied during
274 expansion, for example when building the precondition code from
275 the generated pragma, a new loop parameter must be created for
276 the new tree, to prevent duplicate declarations for the same

513 * exp_disp.adb (Make_Secondary_DT): Handle record type
514 derivations that have interface components located at fixed
515 positions and interface components located at variable offset.
516 The offset of components located at fixed positions is computed
517 using the dummy object (similar to the case where all the

890 'Valid as a replacement for a range check on a discrete type
891 when the bounds of the range are given by type conversions,

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

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