[RFC PATCH v5 0/6] target/mips: Translate MSA vector load/store opcodes

Posted by Philippe Mathieu-Daudé 2 weeks ago

Since v4:
- No algorithm change
- Split to ease review

Hi Richard,

I tried to implement your suggestion from v3 [*]. Unfortunately
the box where I had the MSA test suite got erased, so it will
take me some time to restore the setup. I was surprised these
patches pass our CI tests so I added a pair of abort() which
didn't fire, so this code path isn't tested at all there.
Anyhow, do you mind having a quick look to see this is going
in the right direction?

Thanks!

Phil.
