If 7; register R0 is used before the prologue/epilogue blocks, then it cannot be 8; used to save/restore the LR. 9; 10; TODO: Convert this to an MIR test once the infrastructure can support it. 11; To convert this to an MIR pass, generate MIR after register allocation 12; but before shrink wrapping and verify that has been used in the body of 13; the function. This can be done with something like: 14; llc -stop-after stack-slot-coloring BreakableToken-reduced.ll > BreakableToken-reduced.mir 15; 16; The resulting MIR file can then be used as input to llc, and only run 17; shrink wrapping and Prologue/Epilogue insertion on it. For example: 18; llc -start-after stack-slot-coloring -stop-after prologepilog BreakableToken-reduced.mir 19; 20; Verify in the resulting code that R0 is not used in the prologue/epilogue. 21; 22; This currently cannot be done because the PrologEpilogInserter pass has 23; a dependency on the TargetPassConfig and StackProtector classes, which 24; are currently not serialized when generating the
