[rs6000] Adjust vectorization cost for scalar COND_EXPR
We found that the vectorization cost modeling on scalar COND_EXPR is a bit off
on rs6000. One typical case is 548.exchange2_r, -Ofast -mcpu=power9 -mrecip
-fvect-cost-model=unlimited is better than -Ofast -mcpu=power9 -mrecip (the
default is -fvect-cost-model=dynamic) by 1.94%. Scalar COND_EXPR is expanded
into compare + branch or compare + isel normally, either of them should be
priced more than the simple FXU operation. This patch is to add additional
vectorization cost onto scalar COND_EXPR on top of builtin_vectorization_cost.
The idea to use additional cost value 2 instead of the others: 1) try various
possible value candidates from 1 to 5, 2 is the best measured on Power9. 2)
from latency view, compare takes 3 cycles and isel takes 2 on Power9, it's
2.5 times of simple FXU instruction which takes cost 1 in the current
modeling, it's close. 3) get fine SPEC2017 ratio on Power8 as well.
gcc/ChangeLog
* config/rs6000/rs6000.c (adjust_vectorization_cost): New function.
(rs6000_add_stmt_cost): Call adjust_vectorization_cost and update
stmt_cost.

My change was valid for targets that have a vector/scalar shift/rotate optabs

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.

A call as the immediate operand of decltype is handled differently; we don't

[AArch64] Don't allow partial SVE modes in GPRs
With -msve-vector-bits=N, the payload of some partial SVE modes can
be 16 bytes or smaller, which makes them small enough to fit in a
pair of GPRs. We specifically don't want that, because the payload
is distributed evenly across the SVE register rather than collected
at one end. Marshalling it into a GPR via register operations would
be expensive.
