    True, in this case it's not reporting a missing register ADDR_REGS.

    True, in this case it's not reporting a missing register ADDR_REGS.

    It's a different bug, see: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=1
    22438

    The bug report for the scipy issue is: https://gcc.gnu.org/bugzilla/show_bu g.cgi?id=122479

    Thanks for clarifying, Adrian.
    Great to see they're both getting fixed.
