[Qemu-devel] [PULL 2/7] fp-bench: remove wrong exponent raise in fill_random

[Alex Bennée]

From: "Emilio G. Cota" <address@hidden>

At this point random_ops[] only contains normals, so there's
no need to do anything to them. In fact, raising the exponent
here can make the output !normal, which is precisely
what the comment says we want to avoid.
