It has a global view of the code base and support a lot of cross reference features, see [wiki/FAQ](../../wiki/FAQ).

ccls can index itself (~180MiB RSS when idle, noted on 2018-09-01), FreeBSD, glibc, Linux, LLVM (~1800MiB RSS), musl (~60MiB RSS), ... with decent memory footprint. See [wiki/Project-Setup](../../wiki/Project-Setup) for examples.
