6 ./miri install <flags>:
7 Installs the miri driver and cargo-miri. <flags> are passed to `cargo
8 install`. Sets up the rpath such that the installed binary should work in any
12 Just build miri. <flags> are passed to `cargo build`.
15 Just check miri. <flags> are passed to `cargo check`.
18 Build miri, set up a sysroot and then run the test suite. <flags> are passed
19 to the final `cargo test` invocation.
22 Build miri, set up a sysroot and then run the driver with the given <flags>.
24 The commands above also exist in a "-debug" variant (e.g. "./miri run-debug
25 <flags>") which uses debug builds instead of release builds, for faster build
26 times and slower execution times.
29 Format all sources and tests. <flags> are passed to `rustfmt`.
31 ./miri clippy <flags>:
32 Format all sources and tests. <flags> are passed to `cargo clippy`.
37 If already set, the "sysroot setup" step is skipped.
40 Pass extra flags to all cargo invocations.
