; This used to be classified as a tail call because of a mismatch in the
; arguments seen by Analysis.cpp and ISelLowering. As seen by ISelLowering, they
; both return {i32, i32, i32} (since i64 is illegal) which is fine for a tail
; call.

; As seen by Analysis.cpp: i64 -> i32 is a valid trunc, second i32 passes
; straight through and the third is undef, also OK for a tail call.

; Analysis.cpp was wrong.

; FIXME: in principle we *could* support some tail calls involving truncations
; of illegal types: a single "trunc i64 %whatever to i32" is probably valid
; because of how the extra registers are laid out.
