--- Comment #6 from Tom de Vries <vries at gcc dot gnu.org> ---
There's a call to compute_outgoing_frequencies in find_many_sub_basic_blocks.
But it's not reached for bb4, because STATE(bb4) == BLOCK_TO_SPLIT, and we
trigger the continue here:
...
else
/* If nothing changed, there is no need to create new BBs. */
if (EDGE_COUNT (bb->succs) == n_succs[bb->index])
continue;
compute_outgoing_frequencies (bb);
}
...
Commenting out the else clause gets rid of the ICE.
