Hi John, configure still exits, when checking for uint64_t. I've attached a patch, that properly will fix it.

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
