# Checking conditional configurations

`rustc` accepts the `--check-cfg` option, which specifies whether to check conditions and how to

check them. The `--check-cfg` option takes a value, called the _check cfg specification_.

enables this per default because it is needed for [Stacked Borrows] and [Tree Borrows].

Moreover, Miri recognizes some environment variables (unless noted otherwise, these are supported

by all intended entry points, i.e. `cargo miri` and `./miri {test,run}`):
|
||||
|
||||
* `MIRI_AUTO_OPS` indicates whether the automatic execution of rustfmt, clippy and toolchain setup
|
||||
should be skipped. If it is set to `no`, they are skipped. This is used to allow automated IDE
|
||||
actions to avoid the auto ops.
|
||||
* `MIRI_LOG`, `MIRI_BACKTRACE` control logging and backtrace printing during
|
||||
Miri executions, also [see "Testing the Miri driver" in `CONTRIBUTING.md`][testing-miri].
|
||||
* `MIRIFLAGS` (recognized by `cargo miri` and the test suite) defines extra
|
||||
flags to be passed to Miri.
|
||||
* `MIRI_LIB_SRC` defines the directory where Miri expects the sources of the
|
||||
standard library that it will build and use for interpretation. This directory
|
||||
must point to the `library` subdirectory of a `rust-lang/rust` repository
|
||||
checkout.
|
||||
* `MIRI_SYSROOT` (recognized by `cargo miri` and the Miri driver) indicates the sysroot to use. When
|
||||
using `cargo miri`, this skips the automatic setup -- only set this if you do not want to use the
|
||||
automatically created sysroot. For directly invoking the Miri driver, this variable (or a
|
||||
`--sysroot` flag) is mandatory. When invoking `cargo miri setup`, this indicates where the sysroot
|
||||
will be put.

`cargo miri setup`, this indicates where the sysroot will be put.

|
||||
architecture to test against. `miri` and `cargo miri` accept the `--target` flag for the same
|
||||
purpose.
|
||||
* `MIRI_TEST_THREADS` (recognized by the test suite): set the number of threads to use for running tests.
|
||||
By default the number of cores is used.
|
||||
* `MIRI_NO_STD` (recognized by `cargo miri`) makes sure that the target's sysroot is built without
|

libstd. This allows testing and running no_std programs.
|

(Miri has a heuristic to detect no-std targets based on the target name; this environment variable
|

is only needed when that heuristic fails.)
