And with that, half of the problematic tests appearing with --regalloc=fast flag started working. Unfortunately the second half started to miscompile :( Also, I now s...

But with r103488, I get a:

I just changed the default register allocator for -O0 builds to the fast allocator. This means that the local register allocator is not used anymore, and since it does more or less the same as the fast allocator, there is no reason to keep it around. I am going to delete it in a week or two. If you are using the local register allocator, please try switching to the fast allocator and report any

This switches virtio to use the DMA API unconditionally. I'm sure it breaks things, but it seems to work on x86 using virtio-pci, with and without Xen, and using both the modern 1.0 variant and the legacy variant. This appears to work on native and Xen x86_64 using both modern and legacy virtio-pci. It also appears to work on arm and arm64. It definitely won't work as-is on s390x, and
