Rename diagnostic_context's "printer" field to "m_printer",
for consistency with other fields, and to highlight places
where we currently use this, to help assess feasibility
of supporting multiple output sinks (PR other/116613).
No functional change intended.

Integrate diagnostic messages using the new implementation to the codebase.
New diagnostic implementation uses GNAT.Lists as a building
block. Tampering checks that were initially implemented

The parsing to compute the checksums of runtime files (within the
binder) was done using the default Ada version (Ada 2012 currently),
while the creation of the checksum, when the runtime files are
compiled, is performed in a more recent Ada version (Ada 2022
currently). This change forces the checksum computation for runtime
files to be done with the same Ada version as when they were created.

Some ancient 32-bit ABIs, most notably that of x86/Linux, misalign double

The change causes more temporaries to be created at call sites for unaligned

The initial implementation of the GNAT aspect/pragma Volatile_Full_Access
made it incompatible with Atomic, because it was not decided whether the
read-modify-write sequences generated by Volatile_Full_Access would need
to be implemented atomically when Atomic was also specified, which would
have required a compare-and-swap primitive from the target architecture.
But Ada 2022 introduced Full_Access_Only and retrofitted it into Atomic
in the process, answering the above question by the negative, so the
incompatibility between Volatile_Full_Access and Atomic was lifted in
Ada 2012 as well, unfortunately without adjusting the implementation.
gcc/ada/
* gcc-interface/trans.cc (get_atomic_access): Deal specifically with
nodes that are both Atomic and Volatile_Full_Access in Ada 2012.

This has historically been done only on platforms requiring the strict
alignment of memory references, but this can arguably be considered as

The non-strict overflow checking code does a better job of eliminating
overflow checks if given an expression consisting only of predefined
operators (including relationals), literals, identifiers, and conditional
expressions. If it is both feasible and useful, rewrite a
Length attribute reference as such an expression. "Feasible" means
"index type is same type as attribute reference type, so we can rewrite without
using type conversions". "Useful" means "Overflow_Mode is something other than
Strict, so there is value in making overflow check elimination easier".
gcc/ada/
* exp_attr.adb (Expand_N_Attribute_Reference): If it makes sense
to do so, then rewrite a Length attribute reference as an
equivalent conditional expression.

in the process, answering the above question by the negative, so the
incompatibility between Volatile_Full_Access and Atomic was lifted in
Ada 2012 as well, but the implementation was not entirely adjusted.
In Ada 2012, it does not make sense to warn for the partial access to an
Atomic object if the object is also declared Volatile_Full_Access, since
the object will be accessed as a whole in this case (like in Ada 2022).
gcc/ada/

Do not pass null for the Collection parameter when
Finalize_Storage_Only is in effect. If the collection
is null in that case, we will blow up later when we
deallocate the object.
gcc/ada/
* exp_ch6.adb (Add_Collection_Actual_To_Build_In_Place_Call):
Remove Finalize_Storage_Only from the code that checks whether to
pass null to the Collection parameter. Having done that, we don't
need to check for Is_Library_Level_Entity, because
No_Heap_Finalization requires that. And if we ever change
No_Heap_Finalization to allow nested access types, we will still
want to pass null. Note that the comment "Such a type lacks a
collection." is incorrect in the case of Finalize_Storage_Only;
such types have a collection.

When changing the scope for entities found in the entry body that is
mutated into a procedure, the compiler needs to look deeper than only
the top level entities as expansion may produce object declarations
which scopes are also the entry. For example, the tree after expansion
may look like:
procedure This_Is_An_Entry_Proc is
...
O1 : Typ := do
TMP1 : OTyp := ...;
...
in TMP1;
O1's scope needs to be reset to This_Is_An_Entry_Proc, but so does
TMP1's scope.
This change also fix a small oversight where
N_Implicit_Label_Declaration scope must be reset and its content
skipped.
gcc/ada/
* exp_ch9.adb (Reset_Scopes_To): Adjust comment.

function Has_Tagged_Limited_Partial_View whose implementation
includes a call to Incomplete_Or_Partial_View, which cannot be
easily be called from Is_Immutably_Limited_Type (because sem_aux,
which is in the closure of the binder, cannot easily "with"
sem_util).
* sem_aux.adb (Is_Immutably_Limited): Include
N_Derived_Type_Definition case when testing Limited_Present flag.

The call is legal because it is made from the body, which has visibility on

For consitency sake the main and continuation messages should
use the same warning characters.
gcc/ada/
* exp_aggr.adb (Expand_Range_Component): Remove extra warning
character. Use same conditional warning char.
* freeze.adb (Warn_Overlay): Use named warning character.
* restrict.adb (Id_Case): Use named warning character.
* sem_prag.adb (Rewrite_Assertion_Kind): Use default warning
character.
|
|
Continuation messages should have the same location
as the main message. If the goal is to point to a different
location then Error_Msg_Sloc should be used to change
the location of the continuation message.
gcc/ada/
* par-ch4.adb (P_Name): Use Error_Msg_Sloc for the location of the
continuation message.
|
|
Ensure that the primary and sub message point
to the same location in order to assure that the
submessages get pretty printed in the correct order.
gcc/ada/
* exp_prag.adb (Expand_Pragma_Inspection_Point): Improve sub
diagnostic generation.

The messages modified in this patch do not have a clear intended
parent. This causes a lot of issues when grouping continuation
messages together with their parent. This can be confusing as it
is not obvious what was the parent message that caused this
problem or in worst case scenarios the message not being printed
alltogether.
These modified messages do not seem to be related to any concrete
error message and thus should be treated as independent messages.
gcc/ada/
* sem_ch12.adb (Abandon_Instantiation): Remove continuation
characters from the error message.
* sem_ch13.adb (Check_False_Aspect_For_Derived_Type): Remove
continuation characters from the error message.
* sem_ch6.adb (Assert_False): Avoid creating a continuation
message without a parent. If no primary message is created then
the message is considered as primary.
gcc/testsuite/ChangeLog:
* gnat.dg/interface6.adb: Adjust test.
|
|
Currently unless pretty printing is enabled we avoid parsing
the message strings for continuation messages. This leads
to inconsistent state for the Error_Msg_Object-s that are
being created.
gcc/ada/
* erroutc.adb (Prescan_Message): Avoid not parsing all of the
message attributes.
* erroutc.ads: Update the documentation.
|
|
Avoid cases where the main message is an error and the
continuation is a warning.
gcc/ada/
* freeze.adb: Remove warning insertion characters from a
continuation message.
* sem_util.adb: Remove warning insertion characters from a
continuation message.
* sem_warn.adb: Use same warning character as the main message.
|
|
Separate the line fitting algorithm from the general line
printing algorithm.
gcc/ada/
* erroutc.ads: Add new method Output_Text_Within
* erroutc.adb: Move the line fitting code to a new method called
Output_Text_Within
|
|
To check validity of data values, we must strip privacy from their
types.
gcc/ada/
* checks.adb (Expr_Known_Valid): Use Validated_View, which strips
type derivation and privacy.
* exp_ch3.adb (Simple_Init_Private_Type): Kill checks inside
unchecked conversions, just like in Simple_Init_Scalar_Type.
|
|
gcc/ada/
* styleg.adb (Check_Line_Max_Length): Add the actual line length
to the diagnostic message.

The compiler was flagging type-mismatch errors on iterated component
associations in array aggregates of form "for C in <iterator_name>",
improperly requiring the type of the iterator to be the array index
type. The parser can't distinguish whether the association is one
involving an actual discrete choice vs. an iterator specification,
and creates an N_Iterated_Component_Association with a Defining_Identifer
and Discrete_Choices, and the analysis phase has to disambiguate this,
determining whether to create an N_Iterator_Specification node for
the association. A related change is to revise the similar code for
iterated associations of container aggregates, to allow forms of
iterator objects other than just function calls.
gcc/ada/
* sem_aggr.adb (Resolve_Array_Aggregate): Add loop over associations to locate
N_Iterated_Component_Associations that do not have an Iterator_Specification,
and if their Discrete_Choices list consists of a single choice, analyze it and
if it's the name of an iterator object, then create an Iterator_Specification
and associate it with the iterated component association.
(Resolve_Iterated_Association): Replace test for function call with test of
Is_Object_Reference, to handle other forms of iterator objects in container
aggregates.

This patch moves the documentation for conditional when constructs out of the
curated set (e.g. into -gnatX0).

In get_best_extraction_insn we use smallest_int_mode_for_size with
struct_bits as size argument. PR115495 has struct_bits = 256 and we
don't have a mode for that. This patch makes smallest_mode_for_size
and smallest_int_mode_for_size return opt modes so we can just skip
over the loop when there is no mode.
