The modification to round time up to even second was added decades ago.
It was done to avoid unneeded recompilations when the project was built
on non-FAT filesystems and then moved to FAT filesystems. Such a
situation is now very rare and does not deserve time distortion.

When expanding a loop entry attribute for a while_loop we construct a

This patch fixes a spurious visibility error on a dispatching call to

* exp_disp.adb (Build_Class_Wide_Check, Replace_Formals): When a
dispatching call tp a subprogram with a class-wide precondition
occurrs in the same declarative part as the ancestor subprogram
being called, the`expression for the precondition has not been
analyzed yet. Such a call may appear, e.g. in an expression
function. In that case, the replacement of formals by actuals in
the call cannot use the formal entities of the subprogram being
called, and the occurrence of the formals in the expression must
be located by name (Chars fields) as would be done at a later
freeze point, when the expression is resolved in the context of
the subprogram itself.

If a variable has pragma Persistent_BSS, the compiler now automatically
suppresses implicit initializations caused by Initialize_Scalars and
Normalize_Scalars. Variables with Persistent_BSS cannot be initialized,
and previously a pragma Suppress_Initialization was required before the
pragma Persistent_BSS.

* sem_prag.adb (Persistent_BSS): If an initialization is present

It's illegal to call a function with a result of an immutably limited
type inside a type conversion that's used in one of the special contexts
that allow such a function call by itself (see RM 7.5 (2.1-2.10)), such
as in the initialization expression of an object declaration. The
compiler was recursively applying OK_For_Limited_Init_In_05 to the
expression inside of a rewritten type conversion, rather than directly
to the Original_Node itself (which is what was cased on to get to the
type conversion case alternative), which allowed such illegal
initialization, and that's corrected by this fix. However, when the
expression is not a rewriting of a user-written conversion, the
recursive call to OK_For_Limited_Init_In_05 must be applied to the
Expression of the conversion.

Where possible GNAT will store the binary representation of a record
aggregate in memory for space and performance reasons. This
configuration pragma changes this behaviour so that record aggregates
are instead always converted into individual assignment statements.
The following package pack.ads:
-- pack.ads
pragma Aggregate_Individually_Assign;
pragma Restrictions (No_Multiple_Elaboration);
package Pack is
type A_Rec is record
A, B, C, D : Boolean;
end record;
A : A_Rec := (True, False, True, True);
end Pack;
when compiled with
gcc -c -gnatdg pack.ads
should produce the following output:

This change is aimed at removing a couple of linear searches in the
units management code that can become problematic performance-wise when
the number of loaded units is in the several hundreds, which can happen
for large files even at -O0 without any inlining.
It introduces an auxiliary hash table to record a mapping between the
name of units and their entry in the units table, and then replaces the
linear searches by lookups in this names table. This can save up to 2%
of the compilation time spent in the front-end in some cases.
There should be no functional changes, except in the error message
issued for circular unit dependencies in very peculiar and convoluted
cases.

Years ago, we adapted Get_Kind_Of_Unit so that gnatprove could use it to
detect both bodies and specs of predefined units.
However, this wasn't really needed: gnatprove could simply reuse
Lib.In_Predefined_Unit and now it does. This patch simply reverts two
commits mentioned above.
No frontend test provided, because the removed comment is clear that this
doesn't affect the compiler. Other tools similarly should not be affected

This patch adds a flag that tells targets whether an argument

assign_parm_data_one::passed_pointer in function.c.
The flag is set automatically for places that call
apply_pass_by_reference_rules. Places that apply
pass-by-reference manually need to set it themselves.

manually. They all go through apply_pass_by_reference_rules.)

This patch adds a function_arg_info field to assign_parm_data_one,
so that:
- passed_type -> arg.type
- promoted_mode -> arg.mode
- named_arg -> arg.named
We can then pass this function_arg_info directly to the converted
hooks.
Between the initialisation of the assign_parm_data_one and the
application of promotion rules (which is a state internal to
assign_parm_find_data_types), arg.mode is equivalent to passed_mode
(i.e. to TYPE_MODE).

This patch adds a helper routine that applies pass-by-reference
semantics to an existing function_arg_info.
The c6x part means that c6x_function_arg and c6x_function_arg_advance
see the same "named" value as pass_by_reference did, rather than
pass_by_reference seeing "true" and the others seeing "false".
This doesn't matter because the c6x port doesn't care about namedness.
The rs6000.c patch removes an assignment to "type", but the only
later code to use it was the patched promote_mode line.
(The reason for patching these places despite the above is that
often target code gets used as a basis for new targets or changes
to existing ones.)

The hook is passed the promoted mode instead of the original type mode.
The expr.h reference in the documentation is no longer correct, but
pointing to calls.h or calls.c doesn't help much either. I just left
this as-is since it's not related to the point of the series.
After previous changes, most places already pass arg.mode and arg.type.

The hook is passed the unpromoted type mode instead of the promoted mode.
The aarch64 definition is redundant, but worth keeping for emphasis.

There seems to be a bit of confusion around this one. Almost all
callers pass the same arguments as TARGET_FUNCTION_ARG, meaning
that the mode is the promoted mode rather than the type mode.
But the calls.c handling for normal typed arguments instead passes
the unpromoted TYPE_MODE (despite passing the promoted mode to
TARGET_FUNCTION_ARG). I've kept this behaviour with a ??? comment.
(The calls.c handling of libgcc functions does pass the promoted
mode though, as does the function.c handling of incoming arguments.)
Also, a couple of the arm callers don't seem to be using the hook
correctly. Again I kept the current choices and added a ??? comment.

This patch makes both TARGET_FUNCTION_ARG and
TARGET_FUNCTION_INCOMING_ARG take a function_arg_info.
They have to be done together since many targets use the
same function for both.
The hooks are passed the promoted mode instead of the original type mode.

This patch adds the function_arg_info class and uses it for
TARGET_ARG_PARTIAL_BYTES.
The hook is passed the promoted mode instead of the original type mode.
The arguments aren't mentioned in the documentation, which is why the
target.def change is so small.
The patch changes "true" to "arg.named" in:
gcc_assert (!epiphany_pass_by_reference (cum, mode, type, /* named */ true));
but epiphany_pass_by_reference doesn't care about the named flag.

With CL 190599, along with what we do in greyobject, we ensure
that we only mark allocated heap objects. As a result we can be
more strict in GC:
- Enable "sweep increased allocation count" check, which checks
that the number of mark bits set are no more than the number of
allocation bits.
- Enable invalid pointer check on heap scan. We only trace
allocated heap objects, which should not contain invalid
pointer.
This also makes the libgo runtime more convergent with the gc
runtime.
