Hi,
this patch makes ipe-pure-const and ipa-type-escape to "tolerate" (ie work on
but not take advantage of) the SSA form. I've bootstrapped/regtested the change
on x86_64-linux with IPA-SSA and running routine bootstrap/regtest on clean
mainline i686-linux now. Will commit it as obvious once testing converge.


Uh, but your patch seems wrong.
How can a type escape through an ssa_name, which is purely local to a
function (IE non-escaping)?
