Ownership checking as done in SPARK should be applied only to SPARK
code, which requires GNATprove knowledge of the SPARK_Mode boundary.
Transform the checking unit into a generic to allow passing in the
knowledge from GNATprove to that unit in GNAT sources.
Keeping the code in GNAT sources makes it possible in the future to
adapt it further (or simply instantiate it differently) to be used on
Ada code, independently of GNATprove.
There is no impact on compilation.

* gnat1drv.adb: SPARK checking rules for pointer aliasing are
moved to GNATprove backend.
* sem_spark.ads, sem_spark.adb (Sem_SPARK): Is now a generic
unit. Takes as parameters:
- Retysp which is used to query the most underlying type
visible in SPARK. We do not introduce aliasing checks for
types which are not visibly deep.
- Component_Is_Visible_In_SPARK is used to avoid doing pointer
aliasing checks on components which are not visible in SPARK.
- Emit_Messages returns True in the second phase of 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.
(Check_Expression): Handle delta constraints.
(Is_Deep): Exported so that we can check for SPARK restrictions
on deep types inside SPARK semantic checkings.
(Is_Traversal_Function): Exported so that we can check for SPARK
restrictions on traversal functions inside SPARK semantic
checkings.
(Check_Call_Statement, Read_Indexes): Check wether we are

For some time the Repinfo unit has been able to output the
representation information in the JSON data interchange format in
addition to the usual text and binary formats.
The new Repinfo.Input unit makes it possible to read back this
information under this format and make it available to clients, the main
one being ASIS.
The big advantage of using this approach over manipulating a binary blob
is that the writer and the reader of the JSON representation need not be
binary compatible, i.e. in practice need not be the same version of the
compiler or ASIS for the same target.
The patch also adds a -gnatd_j switch to read back the information in
the compiler itself, which makes it easy to keep the writer and the
reader in sync using only one tool, namely the compiler. The typical
usage is:
gcc -c p.ads -gnatR4js
gcc -c p.ads -gnatd_j
to exercise respectively the writer and the reader from the compiler.

As a lexical element an integer literal has type Universal_Integer, i.e
is compatible with any integer type. This is semantically consistent and
simplifies type checking and subsequent constant folding when
applicable. An exception is caused by 64-bit modular types, whose upper
bound is not representable in a non-static context that will use 64-bit
integers at run-time. For such cases we need to preserve the information
that the analyzed literal has that modular type. For simplicity we
preseve the information for all integer literals that result from a
modular operation. This happens after prior analysis (or construction)
of the literal, and after type checking and resolution.

This patch fixes a compiler abort on an extended return statement whose
expression is an aggregate (to be built in place) for a discriminated
record with a limited component. The build-in-place mechanism creates an
access type and a renaming declaration through which individual
components are assigned. The renamed object is constrained because it is
limited, and the renaming declaration does not need to create a local
subtype indication for it, which may lead to type mismatches in the
back-end, and is in any case redundant. This patch extends this
optimization to the case of records that are limited only because of a
limitied component, and not because they are explicit declared limited.

This patch updates certain error messages to eliminate spelling
mistakes. No need for a test as this is a minor cosmetic fix.

This adds a new GNAT.Branch_Prediction package to make it possible to
tune the branch probability heuristics more finely. This package
contains the equivalent of __builtin_expect in C/C++ plus a couple of
specializations.
The following program gives a summary of the usage:
package Q is
I : Integer;
pragma Volatile (I);
end Q;
with GNAT.Branch_Prediction; use GNAT.Branch_Prediction;
with Text_IO; use Text_IO;
with Q; use Q;
procedure P is
begin
if Unlikely (I = 0) then
Put_Line ("Zero was passed");
return;
end if;
if Likely (I > 0) then
Put_Line ("A positive number was passed");
else
Put_Line ("A negative number was passed");
end if;
if Expect ((I rem 2) = 0, False) then
Put_Line ("An even number was passed");
else
Put_Line ("An odd number was passed");
end if;
end;

For analysis tools that rely on information generated in ALI files, but
do not generate object files, the frontend did not generate the special
extension names like file~2.ali for unit 2 in the file. This is needed
to be able to analyze files with multiple units. Now fixed.
There is no impact on compilation.

* osint-c.adb (Set_File_Name): Always add extension for multiple
units per file mode.

Some VxWorks headers are relying on types that are defined in
`vxWorks.h` but do not include it themselves, we move the include
directive for `vxWorks.h` at the top of the include directives.

gcc/ada/
* sysdep.c: Put include directive for 'vxWorks.h' before any
other VxWorks headers.

This patch modifies the expansion of case expressions to prevent a
spurious error caused by the use of assignment statements to capture the
result of the case expression when the associated type is limited.
2019-07-10 Hristian Kirtchev <kirtchev@adacore.com>
gcc/ada/
* exp_ch4.adb (Expand_N_Case_Expression): Mark the generated
assignments to the temporary result as being OK because the
expansion of case expressions is correct by construction.
(Is_Copy_Type): Update the predicate to match the comment
within.
gcc/testsuite/
* gnat.dg/limited2.adb, gnat.dg/limited2_pack_1.adb,
gnat.dg/limited2_pack_1.ads, gnat.dg/limited2_pack_2.adb,
gnat.dg/limited2_pack_2.ads: New testcase.
