[PATCH] D47482: [AArch64][SVE] Asm: Support for FDUP_ZI (copy fp immediate) instruction.

[Florian Hahn via Phabricator via llvm-commits]

fhahn added a comment.

> I think the difference with other immediates that have a limited set, is that these immediates have a non-trivial parsing/decoding/printing. Rather than just allowing a given range of integer values the string is first parsed as FP value and then encoded as integer value between 0-255. And the opposite for the decode. I think it makes sense to test these cases individually, although I can see how doing this for the FMOV alias as well could be a bit excessive, so I'll reduce those.

Thanks, that makes sense.
