Changes v1->v2:
- Keep MAX_TUPLE_SIZE=0 and update accesses to acle_vector_types
accordingly.
- implement arm_array_mode in patch 4/4 instead of 2/4 to avoid
temporary regressions when running the testsuite at patch 2/4 (helps
future bisects)
This patch series re-implements the intrinscs for loads and stores of
2- and 4- tuples using the new framework.
Most of the code is very similar to the aarch64 counterpart.
Patch #1 adds new modes, similar to aarch64's Advanced SIMD ones for
q-registers.
Patch #2 updates and fixes support for tuple types in the MVE
intrinsics framework.
Patch #3 makes use of the fixes in patch #2 to include tuples in the
store shape description.
Patch #4 is the main one, which updates a few places in arm.cc where
we handled only VALID_NEON_STRUCT_MODE: since we now have a different
VALID_MVE_STRUCT_MODE, a couple of placed needed a fix.
The introduction of all these new modes instead of just OImode and
XImode makes a few parts more verbose though.
This patch series applies on top of the previous one "Rework
store_scatter and load_gather intrinsics".
