These are no longer used in favor of clang-coverage-based solutions.

# -----------------------------------------------------------------

# Make target for line coverage. This target generates a zip file

# called `line_coverage_profiles.zip` that contains a large set of

# zip files one for each fuzz target/critical component. Each zip

# file contains a set of profile files (*.gcno) that we will use

# to generate line coverage reports. Furthermore, target compiles

# all fuzz targets with line coverage instrumentation enabled and

# packs them into another zip file called `line_coverage_profiles.zip`.

#

# To run the make target set the coverage related envvars first:

# 	NATIVE_COVERAGE=true NATIVE_COVERAGE_PATHS=* make haiku-line-coverage

# -----------------------------------------------------------------



# TODO(b/148306195): Due this issue some fuzz targets cannot be built with

# line coverage instrumentation. For now we just block them.
