Store nightly snapshot in rust-toolchain file, and use it in cargo.sh The rust-toolchain file can also store an exact nightly snapshot (instead of just "nightly"), so we can store whatever snapshot that rustc_codegen_cranelift is known to work with. This also lets us add a new feature to `cargo.sh` to let it use the exact same nightly snapshot as cg_clif. If there's a nightly compiler mismatch, you get a confusing error message like: error: couldn't load codegen backend "librustc_codegen_cranelift.so": "librustc_driver-681e2b4f66c73d3e.so: cannot open shared object file: No such file or directory" So doing this automatically in cargo.sh is useful. 2020-01-15 11:05:18 -06:00
