New Revision: 329093
URL: https://svnweb.freebsd.org/changeset/base/329093

Log:
  Promote llvm-cov to a standalone option
  
  Introduce WITH_/WITHOUT_LLVM_COV to match GCC's WITH_/WITHOUT_GCOV.
  It is intended to provide a superset of the interface and functionality
  of gcov.
  
  It is enabled by default when building Clang, similarly to gcov and GCC.
  
  This change moves one file in libllvm to be compiled unconditionally.
  Previously it was included only when WITH_CLANG_EXTRAS was set, but the
  complexity of a new special case for (CLANG_EXTRAS | LLVM_COV) is not
  worth avoiding a tiny increase in build time.
