Possible fix |
||
I bisected this to LLVM r182062: 'Generate debug info for by-value struct args even if they are not used.' Enabling the DEBUG code in SelectionDAGISel::LowerArguments(), it complains that "LowerFormalArguments emitted a null value!". I suspect SITargetLowering::LowerFormalArguments() needs to be adapted for this, but I'm not sure how. Christian, can you take a look?
