"""
Generate build dependencies for Cargo.
The `build.py` script is invoked by cargo when building cranelift-codegen to
generate Rust code from the instruction descriptions. Cargo needs to know when
it is necessary to rerun the build script.
If the build script outputs lines of the form:
cargo:rerun-if-changed=/path/to/file
cargo will rerun the build script when those files have changed since the last
build.
