--- Comment #1 from Dragan Mladjenovic <dragan.mladjeno...@rt-rk.com> --- The issue seems to be that jump pass tail merges two blocks ending in indirect calls to mit_tsi.isra.2 and emit_branch.isra.5 ignoring the REG_CALL_DECL notes attached to them which messes up the resource info later on for delay slot filler.
