I tried leslie3d on PPC. The alias-improvements branch does indeed seem to fix
the issue. The version of leslie3d built with the alias-improvements branch is
about 10% faster than a version built with trunk, and

This is btw very likely fixed on the alias-improvements branch. SPEC testing
that for PPC would be much appreciated.
OTOH I agree with Paolo, so ... FIXED for 4.4, WONTFIX for 4.3.

Btw, on x86_64 leslie3d performance is now above that from before r126326.
The differences you mention can be seen on x86_64 as well, but they are
not related to aliasing or partitioning but due to differences in

Missing jump-threading causes quite a number of missed FRE opportunities, we
have
if (i2 = 0)
{
... = load X
}
if (i2 = 0)
{
... = load X
}
where we figure out the redundancy

Yes, the perfect pass problem is what concerns me too. For example, if we
try to do dynamic reordering of passes, or allow users to specify that, we have
to worry that, in practice, the compiler will crash or

We are putting the HEAP tag for D.914_385 and wav in the same partition:
bb 198:

D.1264_629 = i_25 + -1;

Just following up with comments posted on irc. The patch does fix the problem
I was seeing. Spec ratio improved from 5.18 to 9.07 with the patch (75%), not
quite the full 100% improvement I was seeing with
