New Revision: 343713
URL: https://svnweb.freebsd.org/changeset/base/343713
Log:
Enable COVERAGE and KCOV by default on arm64 and amd64.
This allows userspace to trace the kernel using the coverage sanitizer
found in clang. It will also allow other coverage tools to be built as
modules and attach into the same framework.
