Subject: target/arm: Handle FPROUNDING_ODD in arm_rmode_to_sf
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ab9ced73fa6679791c61d45768414cec578b6053;p=qemu.git

target/arm: Handle FPROUNDING_ODD in arm_rmode_to_sf

While this enumerator has been present since the first commit,
it isn't ever used.  The first actual use of round-to-odd came
with SVE, which currently uses float_round_to_odd instead of
the arm-specific enumerator.

Amusingly, the comment about unhandled TIEAWAY has been
out of date since the initial commit of translate-a64.c.
