svn commit: r325212 - in projects/runtime-coverage: etc/mtree tests tests/tools

[Ngie Cooper]

Author: ngie
Date: Tue Oct 31 05:04:03 2017
New Revision: 325212
URL: https://svnweb.freebsd.org/changeset/base/325212

Log:
  Start adding in simple wrapper around lgov/genhtml called gather_coverage
  
  It will be installed to /usr/tests/tools for the time being
  
  Based loosely on make snippet seen in
  https://github.com/yaneurabeya/scratch/blob/master/demos/freebsd/runtime-coverage/Makefile .
  The real difference is that one needs to run a binary with coverage compiled
  in before running this script, so it can hoover up the .gcda's.

  projects/runtime-coverage/tests/tools/Makefile   (contents, props changed)
  projects/runtime-coverage/tests/tools/gather_coverage.sh   (contents, props changed)
