--- Comment #5 from ktkachov at gcc dot gnu.org ---
The problem is exacerbated by my patch, but the root cause for the state-space
explosion seems to be the extremely large reservation duration for the floating
point div reservations.
I'll see if we can reduce them without any negative impact on codegen quality.
