[PULL 042/101] target/ppc: Use helper_todouble in do_frsp
Posted by Cédric Le Goater 4 years, 1 month ago
From: Richard Henderson <richard.henderson@linaro.org>

We only needed one ieee arithmetic operation to raise
exceptions.  To convert back to register form, we can
use our simpler non-arithmetic function.
