Following up a bit late here:
I am curious about what would cause the slowdown. What kind of operations does that 1.8% slowdown benchmark perform. Does it use the same stack slot a lot? Or is is the generated code a bit bigger after this PR?
That was when using Cranelift in Spidermonkey (see instructions to know how to use a local Cranelift clone in Spidermonkey), and on the Embenchen suite, if you'd like to investigate and give it a try by yourself. Unfortunately, I don't have time to look into this, since I'm focusing on the new isel/regalloc backends right now. It'd be nice that new encodings for machine instructions be added to the new isel backend, in general.
