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14 involves a Ghost aspect it may have been replaced by a null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

46 the shortcut based on Is_Inlined to the back-end inlining case.
48 2019-08-14 Bob Duff <duff@adacore.com>
50 * inline.adb (Check_And_Split_Unconstrained_Function): Ignore
51 protected functions to get rid of spurious error. The
52 transformation done by this procedure triggers legality errors
53 in the generated code in this case.
55 2019-08-14 Bob Duff <duff@adacore.com>
57 * sem_prag.adb (Process_Compile_Time_Warning_Or_Error): Defer
58 processing to the back end in all cases where the pragma's
59 condition is not known at compile time during the front end
60 (except in generics), as opposed to detecting 'Size attributes
61 and the like. This ensures that we take advantage of whatever
62 can be compile-time known after running the back end, as opposed
63 to having the front end guess what the back end can do. Remove
64 a little duplicated code at the call site.
65 * gnat1drv.adb (Post_Compilation_Validation_Checks): Unlock the
66 Elists while in Validate_Compile_Time_Warning_Errors, because it
67 does analysis and name resolution, which sometimes involves

85 (Node_Table_Size): New constant.
86 (Node_Header_Num): New subtype.
87 (Node_Hash): New function.
88 (To_Pending_Instantiations): New hash table.
89 (Add_Inlined_Body): Bail out early for subprograms in the main
90 unit or subunit. Likewise if the Is_Called flag is set. If the
91 subprogram is an instance, invoke Add_Inlined_Instance. Call
92 Set_Is_Called earlier. If the subrogram is within an instance,
93 invoke Add_Inlined_Instance. Also deal with the case where the
94 call itself is within an instance.
95 (Add_Inlined_Instance): New procedure.
96 (Add_Inlined_Subprogram): Remove conditions always fulfilled.
97 (Add_Pending_Instantiation): Move the defence against ludicruous
98 number of instantiations to here. When back-end inlining is
99 enabled, associate an instantiation with its index in table and
100 mark a few selected kinds of instantiations as always needed.
101 (Initialize): Set Backend_Instances to No_Elist.
102 (Instantiate_Body): New procedure doing the work extracted
104 (Instantiate_Bodies): ...here. When back-end inlining is
105 enabled, loop over Called_Pending_Instantiations instead of
106 Pending_Instantiations.
107 (Is_Nested): Minor tweak.
108 (List_Inlining_Info): Also list the contents of
110 * sem_ch12.adb (Might_Inline_Subp): Return early if Is_Inlined
111 is set and otherwise set it before returning true.
112 (Analyze_Package_Instantiation): Remove the defence against
113 ludicruous number of instantiations. Invoke
114 Remove_Dead_Instance instead of doing the removal manually if
115 there is a guaranteed ABE.
117 2019-08-14 Gary Dismukes <dismukes@adacore.com>
119 * exp_ch3.adb (Predef_Spec_Or_Body): For an equality operation
120 of an interface type, create an expression function (that
121 returns False) rather than declaring an abstract function.
122 * freeze.adb (Check_Inherited_Conditions): Set Needs_Wrapper to
123 False unconditionally at the start of the loop creating wrappers
124 for inherited operations.
126 2019-08-14 Bob Duff <duff@adacore.com>
128 * table.adb: Assert that the table is not locked when increasing
129 Last, even if it doesn't cause reallocation. In other words,
130 assert that on operations that MIGHT cause reallocation.
131 * table.ads: Fix comment accordingly.
133 2019-08-14 Arnaud Charlet <charlet@adacore.com>
135 * doc/gnat_ugn/gnat_and_program_execution.rst: Remove
136 documentation of gnatelim.
138 2019-08-14 Bob Duff <duff@adacore.com>
140 * sem_prag.adb (Validate_Compile_Time_Warning_Error): Attach the
141 warning to the Sloc of the first pragma argument, rather than to
142 the pragma itself. This is to make pragmas processed after the
143 back end use the same Sloc as pragmas processed earlier, in the
144 front end. There's no reason for this discrepancy, and it
145 hinders further work on this ticket.
147 2019-08-14 Bob Duff <duff@adacore.com>
149 * sem.ads (Inside_A_Generic): Remove the ??? comment.
151 2019-08-14 Eric Botcazou <ebotcazou@adacore.com>

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

223 2019-08-14 Ed Schonberg <schonberg@adacore.com>
225 * sem_util.adb (New_Copy_Tree, Visit_Entity): A quantified
226 expression includes the implicit declaration of the loop
227 parameter. When a quantified expression is copied during
228 expansion, for example when building the precondition code from
229 the generated pragma, a new loop parameter must be created for
230 the new tree, to prevent duplicate declarations for the same

315 component is an access to a class-wide type and the type of the
316 context is an access to a tagged type the relevant type is that
317 of the component (since in such case we may need to generate

468 derivations that have interface components located at fixed
469 positions and interface components located at variable offset.

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

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

1116 analysis. Error messages for failed aliasing checks are only
1117 output in this case.
