(Process_Compile_Time_Warning_Or_Error): In parameterless

to cover the case of an instance within a generic unit.
(Process_Compile_Time_Warning_Or_Error): Rename the
two-parameter version to be
Validate_Compile_Time_Warning_Or_Error, and do not export it.
Issue a warning if the condition is not known at compile time.
The key point is that the warning must be given only for pragmas
deferred to the back end, because the back end discovers
additional values that are known at compile time. Previous
changes in this ticket have enabled this by deferring to the
back end without checking for special cases such as 'Size.
(Validate_Compile_Time_Warning_Or_Error): Rename to be
Defer_Compile_Time_Warning_Error_To_BE.
* warnsw.ads, warnsw.adb (Warn_On_Unknown_Compile_Time_Warning):

* inline.adb (Check_And_Split_Unconstrained_Function): Ignore

transformation done by this procedure triggers legality errors
in the generated code in this case.
2019-08-14 Bob Duff <duff@adacore.com>
* sem_prag.adb (Process_Compile_Time_Warning_Or_Error): Defer
processing to the back end in all cases where the pragma's
condition is not known at compile time during the front end
(except in generics), as opposed to detecting 'Size attributes
and the like. This ensures that we take advantage of whatever
can be compile-time known after running the back end, as opposed
to having the front end guess what the back end can do. Remove
a little duplicated code at the call site.
* gnat1drv.adb (Post_Compilation_Validation_Checks): Unlock the
Elists while in Validate_Compile_Time_Warning_Errors, because it
does analysis and name resolution, which sometimes involves
adding Elists.
2019-08-14 Eric Botcazou <ebotcazou@adacore.com>

(Node_Table_Size): New constant.
(Node_Header_Num): New subtype.
(Node_Hash): New function.
(To_Pending_Instantiations): New hash table.
(Add_Inlined_Body): Bail out early for subprograms in the main
unit or subunit. Likewise if the Is_Called flag is set. If the
subprogram is an instance, invoke Add_Inlined_Instance. Call
Set_Is_Called earlier. If the subrogram is within an instance,
invoke Add_Inlined_Instance. Also deal with the case where the
call itself is within an instance.
(Add_Inlined_Instance): New procedure.
(Add_Inlined_Subprogram): Remove conditions always fulfilled.
(Add_Pending_Instantiation): Move the defence against ludicruous
number of instantiations to here. When back-end inlining is
enabled, associate an instantiation with its index in table and
mark a few selected kinds of instantiations as always needed.
(Initialize): Set Backend_Instances to No_Elist.
(Instantiate_Body): New procedure doing the work extracted
from...
(Instantiate_Bodies): ...here. When back-end inlining is
enabled, loop over Called_Pending_Instantiations instead of
Pending_Instantiations.
(Is_Nested): Minor tweak.
(List_Inlining_Info): Also list the contents of
Backend_Instances.
* sem_ch12.adb (Might_Inline_Subp): Return early if Is_Inlined
is set and otherwise set it before returning true.
(Analyze_Package_Instantiation): Remove the defence against

Remove_Dead_Instance instead of doing the removal manually if
there is a guaranteed ABE.
2019-08-14 Gary Dismukes <dismukes@adacore.com>

False unconditionally at the start of the loop creating wrappers
for inherited operations.

* sem_prag.adb (Validate_Compile_Time_Warning_Error): Attach the
warning to the Sloc of the first pragma argument, rather than to
the pragma itself. This is to make pragmas processed after the
back end use the same Sloc as pragmas processed earlier, in the
front end. There's no reason for this discrepancy, and it
hinders further work on this ticket.

aliasing checks on components which are not visible in SPARK.

analysis. Error messages for failed aliasing checks are only
output in this case.
Additionally, errors on constructs not supported in SPARK are
removed as duplicates of marking errors. Components are stored
in the permission map using their original component to avoid
inconsistencies between components of different views of the
same type.
