As well as being a powerful optimization in its own right, I am guessing
that that opens up a lot of opportunities for the stack-manipulation-
annihilation optimization you were talking about in your previous post.

That’s very impressive!

How confident are you that all 106 are correct?

This kind of thing seems like it could be a significant advantage for
RISC-V, if people find that the cost-benefit ratio for writing compilers
for it is better than for 8086, i386, or amd64 (not sure which ISA you
meant by “i86”).
