; Copied from codegen-prepare-addrmode-sext.ll -- for the twoArgsNoPromotion
; function, CGP attempts a type promotion transaction on the sext to replace
; it with %add, but then rolls it back. This involves re-inserting the sext
; instruction between two dbg.value intrinsics, and un-RAUWing the users of
; the sext.
; This test checks that this works correctly in both dbg.value mode, but also
; RemoveDIs non-intrinsic debug-info mode.
