As I understand it -O1 only turns on straightforward optimisations such
as keeping often used local variables in CPU registers.  On a CPU with
many registers, such as the Alpha, this gives a huge performance lift.

I presume you picked up the version of iceweasel I uploaded to the
unreleased distribution?

Now that we have a recent iceweasel/xulrunner built some of its
dependencies are also getting built.  A few more delicacies for people
to munch upon should appear at your favourite mirror within a day or two.
