arm: Fix an incorrect warning when -mcpu=cortex-a55 is used with -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.
(cortex-a55, cortex-a75, cortex-a76, cortex-a76ae): Remove redundant
+simd from architecture specification.

When a type descriptor is needed (for e.g. interface conversion),

Fix libdecnumber handling of non-canonical BID significands (PR middle-end/91226).
As reported in bug 91226, the libdecnumber code used on the host to
interpret DFP values in the BID encoding fails, for _Decimal64 and
_Decimal128, to check for the case where a significand is too large
and so specified in IEEE 754 to be a non-canonical encoding of the
zero significand. This patch adds the required handling of that case,
together with tests both using -O2 (testing this host code) and -O0
(testing libgcc code, which already worked before the patch); the
tests also cover _Decimal32, which already had the required check.
In the _Decimal128 case, where the code previously completely ignored
the case where the first four bits of the combination field are 1100,
1101 or 1110, the logic for determining the correct quantum exponent
in that case is also newly added by this patch, so tests are added for
that as well (again, libgcc already handled it correctly when the
conversion was done at runtime rather than at compile time).
Bootstrapped with no regressions for x86_64-pc-linux-gnu.

[mid-end] Add notes to dataflow insn info when re-emitting (PR92410)
In scheduling passes, notes are removed with `remove_notes` before the
scheduling is done, and added back in with `reemit_notes` once the
scheduling has been decided.
This process leaves the notes in the RTL chain with different insn uid's
than were there before. Having different UID's (larger than the
previous ones) means that DF_INSN_INFO_GET(insn) will access outside of
the allocated array.
This has been seen in the `regstat_bb_compute_calls_crossed` function.
This patch adds an assert to the `regstat_bb_compute_calls_crossed`
function so that bad accesses here are caught instead of going
unnoticed, and then avoids the problem.
We avoid the problem by ensuring that new notes added by `reemit_notes` have an
insn record given to them. This is done by adding a call to
`df_insn_create_insn_record` on each note added in `reemit_notes`.
`df_insn_create_insn_record` leaves this new record zeroed out, which appears
to be fine for notes (e.g. `df_bb_refs_record` already does not set
anything except the luid for notes, and notes have no dataflow information to
record).
We add the testcase that Martin found here
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92410#c2 .
This testcase fails with the "regstat.c" change, and then succeeds with the
"haifa-sched.c" change.
There is a similar problem with labels, that the `gcc_assert` catches
when running regression tests in gcc.dg/fold-eqandshift-1.c and
gcc.c-torture/compile/pr32482.c.
This is due to the `cfg_layout_finalize` call in `bb-reorder.c` emitting
new labels, and these labels not having a dataflow df_insn_info member.
We solve this by manually calling `df_recompute_luids` on each basic
block once this pass has finished.
Testing done:
Ran regression tests on aarch64-none-linux-gnu cross compiler.
Bootstrapped and ran tests on aarch64-none-linux-gnu native.

[GCC, Vect] Fix costing for vector shifts
While looking at the vectorization for following example, we realized that
even though vectorizable_shift function was distinguishing vector shifted
by vector from vector shifted by scalar, while modelling the cost it would
always add the cost of building a vector constant despite not needing it for
vector shifted by scalar.
This patch fixes this by using scalar_shift_arg to determine whether we need
to build a vector for the second operand or not. This causes the test case
below to now vectorize.
