[PATCH][ARM][GAS]: Assembler support to interpret MVE VMOV instruction correctly.
This patch make changes to the assembler to encode MVE VMOV instruction "a" same as "b".
a: VMOV<c><q> <Dd>, <Dm>
b: VMOV<c><q>.F64 <Dd>, <Dm>
gas/ChangeLog:
2019-08-30 Srinath Parvathaneni <srinath.parvathaneni@arm.com>
* config/tc-arm.c (do_neon_mov): Modify "if" statement.
* testsuite/gas/arm/mve-vmov-bad-3.d: New test.
* testsuite/gas/arm/mve-vmov-bad-3.l: Likewise.
* testsuite/gas/arm/mve-vmov-bad-3.s: Likewise.
