Hi David,
Firstly, thanks for caring about ports architectures!
Other than generally not being the same processor, and landau having many more
threads (it uses parallel=32, since there are 4 concurrent builds over 128
threads), there is one potentially important difference; the UltraSparc T1 on
andi uses a 48-bit virtual address space (with any returned addresses being
sign-extended), whereas the T5 on landau has a 52-bit virtual address space. It
could also be something completely different, too, of course.
What machine were you trying to reproduce it on? The sparc64 porterbox, notker,
also uses a T1, so if this is the problem you won't be able to reproduce it
there.
Regards,
James
