Hello, The following patch series enables LLVM coverage support for the Xen hypervisor. This first patches are a re-organization of the gcov support, in order to make the support generic for all coverage technologies. This is mostly a name change from gcov -> cov in several places and files, together with the addition of a Kconfig option in order to enable LLVM coverage. Patch 7 introduces

Hi all, I think using code coverage on baremetal has come up once or twice on llvmdev, but I don't think anyone has actually written up how the workflow works, or what issues come up.  This description is based on work done together with my colleague Weiming Zhao. By "baremetal" here, I mean an embedded environment without an operating system.  We specifically used a ARM target
