[PATCH] D62678: [ARM] Add MVE vector instructions that take a scalar input.

[Simon Tatham via Phabricator via llvm-commits]

simon_tatham added a comment.

Revised the `VIDUP` immediate operand handling so as to draw a distinction between the general concept 'power of 2 which is encoded as a left-shift count in the instruction', and the specific case used in VIDUP which takes a fixed range of inputs and has a custom DiagnosticString as you suggested that explains what it's used for.

Also, while I was adding custom DiagnosticStrings, I realised there could usefully be one on the even- and odd-numbered GPR classes. So I've added those too, which meant changing a couple of existing test files.

Finally, fixed those `bits<5> Rx` fields, and a couple of others I spotted in a more thorough search (including one in the previous patch, ahem).
