Alexandre Oliva [Sun, 18 Oct 2020 20:19:53 +0000 (17:19 -0300)]
revamp ada.numerics.aux

Instead of mapping elementary functions for all types to a single
type, use the intrinsics available for the various base types.

A new Ada.Numerics.Aux_Generic_Float is introduced to explicitly
dispatch, based on the 'Digits attribute of the base type, to the
various newly-added Aux_Short_Float, Aux_Float, Aux_Long_Float, or
Aux_Long_Long_Float.

The Aux_Short_Float unit is implemented in terms of the Aux_Float one,
and the others rely on the elementary functions from the C Math
library for float, double and long double types, respectively.

An Aux_Linker_Options is added, and units that import intrinsics from
libm/libc depend on it to provide the "-lm" linker option if needed.
The option is provided by default, but there is an alternate version
that doesn't, that is used for vxworks targets.

The Aux variant that used to open-code Sin and Cos for the ancient
ppc-darwin, because of insufficient precision in libc, is dropped,
along with the alternate dummy body for Aux.  Both are presumed no
longer needed.

The original Ada.Numerics.Aux is retained, for backward compatibility,
as a wrapper for a newly-added Aux_Compat, that renames
Aux_Long_Float, except on x86, in which an alternate version renames
Aux_Long_Long_Float.

Generic_Elementary_Functions and Generic_Complex_Types are adjusted to
use Aux_Generic_Float, avoiding the type conversions and inefficiencies of
computing results in higher precision than requested.

Generic_Complex_Elementary_Functions is adjusted to enable an
additional instance of the sincos optimization, even without -gnatn.

tree-optimization/97428 - split SLP groups for loop vectorization

This enables SLP store group splitting also for loop vectorization.
For the existing testcase gcc.dg/vect/vect-complex-5.c this then
generates much better code, likewise for the PR97428 testcase.

Both of those have a splitting opportunity splitting the group
into two equal (vector-sized) halves, still the patch enables
quite arbitrary splitting since generally the interleaving scheme
results in quite awkward code for even small groups.  If any
problems surface with this it's easy to restrict the splitting
to known-good cases.

compiler: don't export function type parameter names

When hashing a function type the parameter names are ignored.
Therefore, we should not write them into the export data.
Otherwise, minor changes in the order in which we process the
types can cause the export data to change uselessly, leading to
unnecessary rebuilds.
