# The automake manual recommends thinking of DIST_SUBDIRS as the list of all
# *configured* subdirectories.  The normal autotools model involves
# unconditional configure steps for all/most directories with conditional make
# steps (i.e., conditional inclusion in SUBDIRS).  But in the MPICH case we
# almost always configure exactly the directories that will be included in
# SUBDIRS.  So most additions to DIST_SUBDIRS should be conditional on the same
# condition as the corresponding SUBDIRS addition.

# $(lib_lib@MPILIBNAME@_la_SOURCES) already contains $(mpi_sources)

# local var meaning (for profiling foo/bar/baz.c):
#   dir=foo/bar

#
# Note that we delete all extra ".gcov" files that were not the direct goal,
# even though they contain useful information.  A more robust solution is needed
# in the long run, probably one that uses "--long-file-names --preserve-paths"
# and some postprocessing in a perl script.
#
# Gcov has no good way to deal with source files that have been compiled twice
# into two different object files, such as
#   bcast.c --> {bcast.o,lib_libpmpi_la-bcast.o}
# It still generates a bcast.c.gcov output for each object file.  Long file
# names and preserved paths do not help with this problem.
# What we can do in this case is to move the second files to a separate
# directory, rename name, and run gcov on the new files.
# For the web-based coverage reports, the gcov output for the two files
# needs to be merged; see maint/gcovmerge .
# To make it easier to re-run the coverage generation, we copy, rather than
# move, when there are two object files for each source file.
# A change to the build procedure broke this target.  This is a partial though
# nearly complete fix to the broken build process.  The generated coverage
# files after the fix appear mostly correct, though there appear to also be
# errors in the gcov output itself (the format of this output changes
# frequently).  However, the coverage analysis is still valuable and has
# identified missing tests.
#
# The problem:
#   The source file is foo.c
#   gcov expects foo.o, foo.gcno, and foo.gcda files
#   The MPICH build process, unfortunately, does not produce a foo.o file;
#   instead, it produces a .libs/lib_lib@MPILIBNAME@_la-foo.o file (and
#   similarly .libs/lib_lib@MPILIBNAME@_la_foo.gcno etc.
#   This change broke this coverage target.  If further changes to the
#   naming conventions for object files are made, make sure that the
#   coverage target is also modified to correspond to those changes.
