In case of functions without a stack frame no "stack" field is serialized into MIR which leads to isCalleeSavedInfoValid being false when reading a MIR file back in. To fix this we should serialize MachineFrameInfo::isCalleeSavedInfoValid() into MIR.
This directory contains tests for the MIR file format parser and printer. It was necessary to split the tests across different targets as no single target covers all features available in machine IR. Tests for codegen passes should NOT be here but in test/CodeGen/sometarget. As a rule of thumb this directory should only contain tests using 'llc -run-pass none'.
