-FLAGS:
-    -b, --bad-tests    Include tests expected to fail (will cause a non-zero return code)
-    -f, --format       Enable formatting with `rustfmt`

 ### Filters

 ```bash
 # in the ci/svd2rust-regress folder
-cargo run --release -- -a RiscV
-    Finished release [optimized] target(s) in 0.0 secs
-     Running `target/release/svd2rust-regress -a RiscV`
-Passed: si_five_e310x - 7 seconds

 To run against any chip named `MB9AF12xK`:
 
 ```bash
-cargo run --release -- --long-test -c MB9AF12xK
-    Finished release [optimized] target(s) in 0.0 secs
-     Running `target/release/svd2rust-regress --long-test -c MB9AF12xK`

 To run against specifically the `Fujitsu` `MB9AF12xK`:
 ```bash
-cargo run --release -- --long-test -c MB9AF12xK -m Fujitsu
-    Finished release [optimized] target(s) in 0.0 secs

-Passed: fujitsu_mb9af12x_k - 19 seconds
+cargo regress test -c MB9AF12xK -m Fujitsu

-Note that you may have to pass `--long-test` to enable some chips as they are known to take a long time to compile.
