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
9 working directory. However, the rustup toolchain when invoking `cargo miri`
10 needs to be the same one used for `./miri install`.
13 Just build miri. <flags> are passed to `cargo build`.
16 Just check miri. <flags> are passed to `cargo check`.
19 Build miri, set up a sysroot and then run the test suite. <flags> are passed
20 to the final `cargo test` invocation.
23 Build miri, set up a sysroot and then run the driver with the given <flags>.
24 (Also respects MIRIFLAGS environment variable.)
27 Format all sources and tests. <flags> are passed to `rustfmt`.
29 ./miri clippy <flags>:
30 Runs clippy on all sources. <flags> are passed to `cargo clippy`.
32 ./miri many-seeds <command>:
33 Runs <command> over and over again with different seeds for Miri. The MIRIFLAGS
34 variable is set to its original value appended with ` -Zmiri-seed=$SEED` for
37 ./miri bench <benches>:
38 Runs the benchmarks from bench-cargo-miri in hyperfine. hyperfine needs to be installed.
39 <benches> can explicitly list the benchmarks to run; by default, all of them are run.
44 If already set, the "sysroot setup" step is skipped.
47 Pass extra flags to all cargo invocations.
