[llvm-dev] Deprecating the experimental microMIPS64R6 backend

[Simon Dardis via llvm-dev]

Hi all,

I plan to deprecate the experimental microMIPS64R6 backend for the 5.0 release
and remove it after the release.

Currently there are no CPUs that use that particular sub-ISA which makes it difficult
to justify the maintenance and parallel development effort.

If there was a CPU design produced that did use microMIPS64R6, the backend could
be restored from the archive.

Any comments or objections?

Thanks,
Simon
