@@ -74,11 +74,13 @@ Or, when using `cretonne` as a dependency (in Cargo.toml):
path = "..."
features = ["no_std"]
Currently, tests don't test the `no_std` feature:
`no_std` is currently "best effort". We won't try to break it, and we'll
accept patches fixing problems, however we don't expect all developers to
build and test with `no_std` when submitting patches. Accordingly, the
`./test-all.sh` script does not test `no_std`.
1. `cargo test --features no_std` won't compile.
2. `./test-all.sh` doesn't test the `no_std` feature.
There is a separate `./test-no_std.sh` script that tests the `no_std`
feature in packages which support it.
It's important to note that cretonne still needs liballoc to compile.
Thus, whatever environment is used must implement an allocator.
