COMMANDS
./miri install <flags>:
Installs the miri driver and cargo-miri. <flags> are passed to `cargo
-install`. Sets up the rpath such that the installed binary should work in any
+install`. Sets up the rpath such that the installed binary should work in any
working directory.
./miri build <flags>:
-Just build miri. <flags> are passed to `cargo build`.
+Just build miri. <flags> are passed to `cargo build`.
+
+./miri check <flags>:
+Just check miri. <flags> are passed to `cargo check`.
./miri test <flags>:
Build miri, set up a sysroot and then run the test suite. <flags> are passed
./miri run <flags>:
Build miri, set up a sysroot and then run the driver with the given <flags>.
+(Also respects MIRIFLAGS environment variable.)
-All commands also exist in a "-debug" variant (e.g. "./miri run-debug
+The commands above also exist in a "-debug" variant (e.g. "./miri run-debug
<flags>") which uses debug builds instead of release builds, for faster build
times and slower execution times.
+./miri fmt <flags>:
+Format all sources and tests. <flags> are passed to `rustfmt`.
+
+./miri clippy <flags>:
+Format all sources and tests. <flags> are passed to `cargo clippy`.
+
+./miri many-seeds <command>:
+Runs <command> over and over again with different seeds for Miri. The MIRIFLAGS
+variable is set to its original value appended with ` -Zmiri-seed=$SEED` for
+many different seeds.
