14 This document is a reference manual for the Machine IR (MIR) serialization
15 format. MIR is a human readable serialization format that is used to represent

25 The MIR serialization format uses a YAML container. YAML is a standard

39 You can use the MIR format for testing in two different ways:
41 - You can write MIR tests that invoke a single code generation pass using the
45   tests and check the MIR output of a specific code generation pass.
50 The ``run-pass`` option in llc allows you to create MIR tests that invoke
52 an input MIR file, run the specified code generation pass, and print the
53 resulting MIR to the standard output stream.
55 You can generate an input MIR file for the test by using the ``stop-after``
63 After generating the input MIR file, you'll have to add a run line that uses

92 These limitations impose restrictions on what you can test with the MIR format.
