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