------- Comment #3 from matz at gcc dot gnu dot org 2009-10-03 22:49 -------
Found a nice testcase for exponential explosion. It's reduced from tree.c
(make_vector_type) when building with -fprofile-generate. The testcase needs
simply "-O2 -g" and takes a ridiculous amount of > 4GB RAM.
It's the tree-ssa-sink pass that triggers this in this case (with slight
variations in the testcase I can also make it blow up in RTL fwprop).
This means btw. that profiledbootstrap is broken.
