            Bug ID: 33501
           Summary: Don't instrument tools when compiling with coverage
           Product: Build scripts
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: cmake
          Assignee: unassignedbugs at nondot.org
          Reporter: vsk at apple.com
                CC: llvm-bugs at lists.llvm.org

Tools like llvm-config, count, not, and FileCheck shouldn't be instrumented for
coverage reporting. Doing so substantially slows down testing time, because
large profiles for each binary need to be written out every time they are
invoked.
