tools/dev/gcov.patch

   1 This patch can be used to generate a report showing what C source
   2 lines are executed when the testsuite is run.  gcc is required.  After
   3 applying this patch do:
   4
   5 $ ./configure --enable-gcov
   6 $ make check
   7 $ make gcov
   8
   9 Now look at gcov-report.html and the annotated source files it links
  10 to.

  12 See also gcov(1), gcc(1).
