[Qemu-devel] [PATCH v2 0/9] target-alpha exception improvements

[Richard Henderson]

I never got around to actually posting v1, although I sent a link to the
branch, buried in another thread.  I've rebased the branch and added 3
more patches to cover more issued raised by Al since the v1.

I've used this to clean up all of the errors in glibc mainline wrt
math/test-double.out, due to code that should have failed on real ev6
hw as well.

I still see a few spurrious underflow errors in math/test-float.out,
and I believe it to be an error in float64_to_float32 wrt FLT_MIN,
but I havn't had time to verify that.

Al and Peter, if you could run the mainline glibc math tests on real
hardware, I'd be most grateful.
