I saw phase2/3 mismatches that seem concerning. Are these the only
platforms that encountered them?
I can open a bug, let me know if there's particular data beyond the
logs I should gather.
Can you attach 2 of the binary files the are different?
Attached a few from each impacted platform. Additional notes below.

The difference in ubuntu 10.0.1-rc4 are in the '__nv_module_id'
section of binaries, which contains a GUID that is unique to the
binary, so this is expected.

Do you get these same failures on sles with rc4?
It looks like the difference in the objects on sles is because
the compiler ID string in phase 2 and phase 3 have a different
git commit hash. The git hash in the phase 3 binaries is
acd921f02c39fa5cf7aa055b6062bfe9025e3781, which I don't see in
the llvm git tree.
