It seems the old one was just broken (see mailing list discussion.)
This new one was built from the generic one, but it was done using
a trunk build of Clang 8 with tuned optimization flags, and is
smaller (101 instructions) than GCC 8's (134 instructions) and
the old hand-optimized one (~125 instructions?) as well as being
targeted for ARMv7 instead of ARMv6 like the old one was.
