Hi -

The fact that simple userland programs like regress/lib/libc/ieeefp/except
crashed my DECstation made me nervous, so I've looked into the issue and
found 2 serious problems: incomplete siginfo adaption and lacking FPU status
clearing.
I don't know much about MIPS processors beyond absolutely basic things,
particulary I don't have any idea how 64-bit issues are dealt with, and
what all that coprocessor emulation and softfp stuff is about.
So please check whether I broke something, and forgive me if I did;-)

best regards
Matthias
