To reduce test executable size and speed up compilation time, compile unit
tests into a single executable.
Here is a file size comparison of the unit test executable:
- Before applying the patch
$ du -h --exclude='*.o' --exclude='*.o.d' build/release/test/boost/ build/debug/test/boost/
11G build/release/test/boost/
29G build/debug/test/boost/
- After applying the patch
du -h --exclude='*.o' --exclude='*.o.d' build/release/test/boost/ build/debug/test/boost/
5.5G build/release/test/boost/
19G build/debug/test/boost/
It reduces executable sizes 5.5GB on release, and 10GB on debug.
