--- Comment #6 from Richard Guenther <rguenth at gcc dot gnu.org> 2011-03-22 10:13:49 UTC --- Btw, the minimal partition size is quite small (1000), 10 times smaller than our large-unit-insns inline limit and 2.7 times smaller than our large function inline limit. Upping that limit by a factor of 10 magically solves this problem by only using a single partition automagically (it looks to me that it should be similar to large-unit-insns anyway).
