As explained in the comments, matchSwap matches: // mov t, x // mov x, y // mov y, t and turns it into: // mov t, x (t is potentially dead and move eliminated) // v_swap_b32 x, y On physical registers we don't have full use-def chains so the check for T being live-out was not working properly with subregs/superregs.
