> Bug2: test case provided above. Please Lewis take a look at how this case can be fixed.

Isn't the issue just that the code is checking for PseudoTAIL, and not PseudoTAILIndirect?

----

What happens if a tail call has more than 8 arguments?

What happens for a musttail call?  A tailcc call?  (Not sure if either of those are actually supported on RISCV at the moment?)
