--- Comment #3 from dehao at gcc dot gnu.org ---
We need to rebuild frequency after vrp, otherwise the following code in
tree-ssa-threadupdate.c will make the frequency larger than upper-bound.
/* Excessive jump threading may make frequencies large enough so
the computation overflows. */
if (rd->dup_blocks[0]->frequency < BB_FREQ_MAX * 2)
rd->dup_blocks[0]->frequency += EDGE_FREQUENCY (e);
I'll send out a patch for this.
