If I run:
lcov --output-file $(BUILD_DIR)/coverage_all.info --capture --directory $(BUILD_DIR)
It appears to process each .gcda file one at a time instead of taking advantage of all my cores. Is it possible to rewrite this step so that I can produce the coverage_all.info file while using all my cores?
I'm thinking of something that I would put in a make file and run make with the -j option so it would spawn multiple jobs, each recording their results in a different file. Then when all the jobs complete, I would merge them together, perhaps using the lcov --add-tracefile option.
Does anyone know how to do something like this?
