Deterministic builds with LLVM's GN build
=========================================
Summary: Use the following args.gn.
use_relative_paths_in_debug_info = true
It is possible to produce [locally deterministic][1] builds of LLVM
with the GN build. It requires some configuration though.
1. Make debug info use relative paths by setting
`use_relative_paths_in_debug_info = true` in your `args.gn` file. With this
set, current debuggers need minor configuration to keep working. See
"Getting to local determinism" and "Getting debuggers to work well with
locally deterministic builds" in the [deterministic builds][1] documentation
for details.
