--- Comment #3 from ak at gcc dot gnu.org ---
With -fno-bit-tests -fno-jump-tables it compiles reasonably fast.
One bug is really that these two options are enabled by default even at -O0.
tree-switch-conversion has some logic for this, but it seems to be broken.
Second step would be to figure out how to improve the clustering algorithm
scaling.
