[PATCH] D38315: [ARM] Armv8.2-A FP16 code generation (part 1/2)

[Sjoerd Meijer via Phabricator via llvm-commits]

SjoerdMeijer updated this revision to Diff 131289.
SjoerdMeijer added a comment.

This addressing the straightforward comments:

- the unnecessary calling conv change,
- the mask for the imm8

I agree that the bitcast optimisation is generic, but for now I prefer to have
it working locally first, and we can address this in a follow-up patch.

I am now looking into the SOFTFP-FP16 case which looks like to be doing 
default legalisation for bitcasts.
