Bernd Schmidt <bernds at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |bernds at gcc dot gnu.org --- Comment #2 from Bernd Schmidt <bernds at gcc dot gnu.org> --- -freorder-blocks-algorithm=simple makes the bb-reorder time go down to an insignificant fraction. Probably worth trying to see if we can determine from the CFG whether the STC algorithm is likely to be too expensive.
