[PATCH RISU] arm.risu, thumb.risu: Add v8.2 DP and FHM insns |
Date: |
Mon, 18 May 2020 16:47:19 +0100 |
Add coverage for the v8.2 DP and v8.2 FHM insns in the Neon extension
space. (We already had the v8.1 VQRDMLAH/VQRDLSH and the v8.3
VCADD/VCMLA, so this brings the risu coverage into line with what
QEMU has implemented so far.)

I added these patterns as part of testing for the first part
of the Neon decodetree conversion and forgot I'd never sent out the
risu patch for review.
