The guest code has to use a set of structure offsets and
sizes which is fixed by the virtio ABI -- how it implements
this is up to the guest (and if it misimplements it that is
a guest bug and not our problem). Note also that the ABI
is not defined by a set of C source struct definitions
(except in as far as they are accompanied by a set of
restrictions on alignment, padding, etc that completely
determine the numerical alignments and offsets).
How QEMU implemen...

On the other hand, encouraging both userspace and guest to reuse a
single set of headers means that the bad offset becomes a spec bug more
than a guest bug.

[LLVMdev] Leaks in PBQPBuilderWithCoalescing::build ?
Hi Lang,
In PBQPBuilderWithCoalescing::build, around line 360, we have code looking like:
…
PBQP::Vector newCosts(g.getNodeCosts(node));
addPhysRegCoalesce(newCosts, pregOpt, cBenefit);
g.setNodeCosts(node, newCosts);
…
I suspect the leak occurs around the setNodeCosts method, and I have trouble understanding how it handles the case where the node already has costs.
It seems to

It is not! You can fix __vmalloc now and you can convert the kernel to the
scope API in 4 years. It's not one way or

Per-Request View Paths
I haven''t had a chance to work on fixing multiple controller view paths
recently. My original patch attempt was:
http://dev.rubyonrails.org/ticket/8582
It was rejected due to the fact that it was fixing the symptom more than the
problem.
However, I think it''s critical that this problem get fixed, otherwise the
whole concept of view_paths is severely neutered and
