[Xen-devel] [PATCH v3 0/7] LLVM coverage support for Xen

[Roger Pau Monne <roger.pau@xxxxxxxxxx>]

Hello,

The following patch series enables LLVM coverage support for the Xen
hypervisor. A sample coverage report obtained after booting a PVHv2 Dom0
can be found at:

http://xenbits.xen.org/people/royger/xen_profile/

I know the time is not the most appropriate given all the security work
going on, but it seems like the series is quite close, and I would ike
to avoid it bitrotting.

Thanks, Roger.
