Hello,
This patch supports following MVE ACLE intrinsics with unary operand.
vctp16q, vctp32q, vctp64q, vctp8q, vpnot.
Please refer to M-profile Vector Extension (MVE) intrinsics [1] for more details.
[1] https://developer.arm.com/architectures/instruction-sets/simd-isas/helium/mve-intrinsics
There are few conflicts in defining the machine registers, resolved by re-ordering
VPR_REGNUM, APSRQ_REGNUM and APSRGE_REGNUM.
Regression tested on arm-none-eabi and found no regressions.
Ok for trunk?
Thanks,
Srinath.
