    Fix the Slow calling convention (#7192) · 4270d7e7
    Simon Marlow authored
    The Slow calling convention passes the closure in R1, but we were
    ignoring this and hoping it would work, which it often did.  However,
    this bug seems to have been the cause of #7192, because the
    graph-colouring allocator is more sensitive to having correct liveness
    information on jumps.
