[Qemu-devel] [PATCH v2 00/27] softfloat patch roundup |

This is my SNaN patch set, Alex's float-float refactor, and a couple
of other random outstanding fpu patches. This has been reordered so
as to be bisectable, since the float-float refactor requires the snan
work to avoid breakage.
It probably doesn't matter, but this was built on top of my arm fp16
patch set simply to make it easier to test. The whole tree is
