Hi,
The final (!!!) patch in the series making types equivalent between
AArch64 and ARM backends deals with insns in the AArch64 backend
which generate ldp and stp. We could invent a new type for these and
add that type to all the pipeline descriptions, but I think the types
neon_ldm_2 and neon_stm_2 describe them adequately.
Tested on aarch64-none-elf with no regressions.
OK?
Thanks,
James

* config/aarch64/aarch64.md
(*movtf_aarch64): Use neon_<ls>dm_2 as type where v8type
is fpsimd_<load/store>2.
(load_pair<mode>): Likewise.
(store_pair<mode>): Likewise.
