Wasmtime GitHub notifications bot (Mar 10 2021 at 08:01): Wasmtime GitHub notifications bot (Mar 10 2021 at 08:01):cfallin opened PR #2718 from new-backend to main:
(Note 1: This PR depends on #2710 and includes its commits for CI purposes for now.)
(Note 2: I plan to write an RFC to more fully describe and get consensus on the process of switching over. This is mostly a PR for CI-experimentation and to get some data/confirmation on what's actually left to be done.)
This PR switches the default backend on x86, for both the
cranelift-codegencrate and for Wasmtime, to the new
(MachInst-style,VCode-based) backend that has been under
development and testing for some time now.The old backend is still available by default in builds with the
old-x86-backendfeature, or by requestingBackendVariant::Legacy
from the appropriate APIs.As part of that switch, it adds some more runtime-configurable plumbing
to the testing infrastructure so that tests can be run using the
appropriate backend.clif-util testis now capable of parsing a
backend selector option from filetests and instantiating the correct
backend.I has been updated so that the old x86 backend continues to run its
tests, just as we used to run the new x64 backend separately.At some point, we will remove the old x86 backend entirely, once we are
satisfied that the new backend has not caused any unforeseen issues and
we do not need to revert.

not merge this until we reach consensus on the process described therein
and merge the RFC.

What do the new file test targets (machinst and legacy) mean?

Is this still needed or was this a temporary addition?

or rather, if it's still needed, mind adding a comment as to why?
