* exp_ch9.adb (Build_Protected_Entry): Analyze the block created
to hold the declarations and statements of the protected entry
body right after it's created, and then call Reset_Scopes_To on
that block to reset the Scope of nested entities to the block
scope.
(Reset_Scope): Add handling for N_Freeze_Entity nodes, calling
Reset_Scopes recursively on the Actions of such nodes. Also, for
subprogram bodies that are encountered that might not have a
separate declaration (such as type init procedures), reset the
Scope of the subprogram's entity.

PR 92846:
ARC gcc generates FDCMP instructions which raises Invalid operation for
signaling NaN only. This causes glibc iseqsig() primitives to fail (in
the current ongoing glibc port to ARC)
So break up the hard float compares into tw categories and for unordered
compares generate the FDCMPF instructions which raised exception for
either NaNs.
With this fix testsuite/gcc.dg/torture/pr52451.c passes for ARC.
Also no regressions for the glibc math testsuite, only 6 additional
passes for test*iseqsig

This patch provides a way to clone a pretty_printer.
This is needed so that we can capture text in a label_text and make
layout decisions based on it, using the policy of global_dc's printer,

the pretty_printer itself within a call to diagnostic_show_locus since
it has partly-buffered content.

Ville pointed out that our paren init of aggregates doesn't work for
auto a = new A(1, 2, 3);
and I think it should:
A new-expression that creates an object of type T initializes that object
as follows:
...
-- Otherwise, the new-initializer is interpreted according to the
initialization rules of [dcl.init] for direct-initialization.
so I think it follows that we should perform dcl.init#17.6.2.2.
This doesn't work with new[]; we have:

-mfloat-abi=soft
When a CPU such as cortex-a55 is used with the soft-float ABI variant,
the compiler is incorrectly issuing a warning about a mismatch between
the architecture (generated internally) and the CPU. This is not
expected or intended.
The problem stems from the fact that we generate (correctly) an
architecture for a soft-float compilation, but then try to compare it
against the one recorded for the CPU. Normally we strip out the
floating point information before doing that comparison, but we
currently only do that for the features that can be affected by the
-mfpu option. For a soft-float environment we also need to strip out
any bits that depend on having floating-point present.
So this patch implements that and does a bit of housekeeping at the
same time:
- in arm-cpus.in it is not necessary for a CPU to specify both
+dotprod and +simd in its architecture specification, since +dotprod
implies +simd.
- I've refactored the ALL_SIMD fgroup in arm-cpus.in to create a new
subgroup ALL_SIMD_EXTERNAL and containing the bits that were
previously added directly to ALL_SIMD. Similarly, I've added an
ALL_FPU_EXTERNAL subgroup.
- in arm.c rename fpu_bitlist and all_fpubits to fpu_bitlist_internal
and all_fpubits_internal for consistency with the fgroup bits which
they contain.
* config/arm/arm-cpus.in (ALL_SIMD_EXTERNAL): New fgroup.
(ALL_SIMD): Use it.
(ALL_FPU_EXTERNAL): New fgroup.
(ALL_FP): Use it.

+simd from architecture specification.

(isa_all_fpbits): New bitmap.

package
When a type descriptor is needed (for e.g. interface conversion),
if the type is a pointer to a named type defined in another
package, we don't generate the definition of the type descriptor
because it is generated in the package where the type is defined.
However, if the named type is an alias to an unnamed type, its
descriptor is not generated in the other package, and we need to
generate it.
