; RUN: llc -verify-machineinstrs -mtriple=powerpc64le-unknown-linux-gnu -mcpu=pwr8 -enable-shrink-wrap=true %s -o - | FileCheck %s
;
; Test the use of a non-R0 register to save/restore the LR in function 
; prologue/epilogue.
; This problem can occur as a result of shrink wrapping, where the function
; prologue and epilogue are moved from the beginning/ending of the function. If
; register R0 is used before the prologue/epilogue blocks, then it cannot be
; used to save/restore the LR.
;
; TODO: Convert this to an MIR test once the infrastructure can support it.
;       To convert this to an MIR pass, generate MIR after register allocation
;       but before shrink wrapping and verify that has been used in the body of
;       the function. This can be done with something like: 
;         llc -stop-after stack-slot-coloring BreakableToken-reduced.ll > BreakableToken-reduced.mir
;
;       The resulting MIR file can then be used as input to llc, and only run
;       shrink wrapping and Prologue/Epilogue insertion on it. For example:
;         llc -start-after stack-slot-coloring -stop-after prologepilog BreakableToken-reduced.mir
;       
;       Verify in the resulting code that R0 is not used in the prologue/epilogue.
;
;       This currently cannot be done because the PrologEpilogInserter pass has
;       a dependency on the TargetPassConfig and StackProtector classes, which
;       are currently not serialized when generating the MIR.
