Is csel really better than a branch? true and false are not trivial values and
it probably needs 4 instructions to load each.

[zra, 2014/04/25 21:28:28]

Loading true and false are one instruction each from the start of the object
pool. I'll leave it like this for now, and see what gcc does later.
