-- Elaboration checks --
------------------------
The dynamic ABE checks model now emits the same diagnostics as those of the
static ABE checks model.
The ABE checks mechanism has been redesigned and refactored in the face of
increasing requirements. Most of the functionality can now be toggled, thus
allowing for various combinations of behavior. The combinations are defined
as "initial states" and may be further altered.
Scenarios and targets have been distinctly separated at the higher level,
instead of directly working with nodes and entitites. Scenarios and targets
now carry a representation which removes the need to constantly recompute
relevant attributes, and offers a common interface for the various processors.
Most processing has now been refactored into "services" which perform a single
ABE-related function.
-----------------------
-- Elaboration order --
-----------------------
A new elaboration order mechanism based on the use of an invocation graph to
provide extra information about the flow of execution at elaboration time has
been introduced.
The ABE checks mechanism has been altered to encode pieces of the invocation
graph in the associated ALI files of units.
The new elaboration order mechanism reconstructs the full invocation graph at
bind time, and coupled with the library item graph, determines the elaboration
order of units.
The new elaboration order mechanism is currently inaccessible.

The -gnatw.z switch causes the compiler to issue a warning on record
types subject to both an alignment clause and a size clause, when the
specified size is not a multiple of the alignment in bits, because this
means that the Object_Size will be strictly larger than the specified
size.
It makes sense to extend this warning to array types, but not to the
cases of bit-packed arrays where the size is not a multiple of storage
unit and the specified alignment is the minimum one, because there would
be no way to get rid of it apart from explicitly silencing it.
The compiler must issue the warning:
p.ads:5:03: warning: size is not a multiple of alignment for "Triplet"
p.ads:5:03: warning: size of 24 specified at line 4
p.ads:5:03: warning: Object_Size will be increased to 32
on the following package:
package P is
type Triplet is new String (1 .. 3);
for Triplet'Size use 24;
for Triplet'Alignment use 4;
type Arr is array (1 .. 7) of Boolean;
pragma Pack (Arr);

Revamps the way the exporter tracks exported types and imported
packages that need to be mentioned in the export data.
The previous implementation wasn't properly handling the case where an
exported non-inlinable function refers to an imported type whose
method set includes an inlinable function whose body makes a call to a
function in another package that's not directly used in the original
package.
This patch integrates together two existing traversal helper classes,
"Collect_references_from_inline" and "Find_types_to_prepare" into a
single helper "Collect_export_references", so as to have common/shared
code that looks for indirectly imported packages.
Fixes golang/go#32778

scheduling for Cortex-A57
Some scheduling descriptions, like the Cortex-A57 one, are reused for multiple -mcpu options.
Sometimes those other -mcpu cores support more architecture features than the Armv8-A Cortex-A57.
For example, the Cortex-A75 and Cortex-A76 support Armv8.2-A as well as the Dot Product instructions.
These Dot Product instructions have the neon_dot and neon_dot_q scheduling type, but that type is not
handled in cortex-a57.md, since the Cortex-A57 itself doesn't need to care about these instructions.
But if we just ignore the neon_dot(_q) type at scheduling we get really terrible codegen when compiling
for -mcpu=cortex-a76, for example, because the scheduler just pools all the UDOT instructions at the end
of the basic block, since it doesn't assume anything about their behaviour.
This patch ameliorates the situation somewhat by telling the Cortex-A57 scheduling model to treat any
insn that doesn't get assigned a cortex_a57_neon_type but is actually a is_neon_type instruction as
a simple neon_arith_basic instruction. This allows us to treat post-Armv8-A SIMD instructions more sanely
without having to model each of them explicitly in cortex-a57.md.
