"make clean" does not work for me; it doesn't remove the .gcda and .gcno
files. Apparently the problem is that $(enable_coverage) is not
defined, so that part of common.mk is not called.
Note: one thing to keep in mind is directories like src/port. There are
some .gcda and .gcno files in there too, but even if common.mk is fixed,
they will not be cleaned because src/port does not seem to use
common.mk.
Another thing that I'm unsure about is the coverage_out target. It does
work, but is it running the coverage target each time it is invoked?
Because if so, it's removing all of ./coverage and creating it again ...
is this the desired behavior?
This patch is missing a installation.sgml patch, at a minimum. I think
it would be useful to mention that we support gcov, and the make targets
we have, in some other part of the documentation. I can't readily find
a good spot, but I think a new file to be inserted in the internals
chapter would be appropriate.
Two hunks no longer apply, but that's OK because they were working
around a problem that no longer exists. Other than the minor gripes
above, the patch looks OK to me.
