Hi Alex. The patch has been updated. The codgen result in calling-conv.ll:caller_many_scalars function with FP has changed due to we override the hasReservedCallFrame function. According to the logic in determineFrameLayout, the SP adjustment will change from 32 to 16. It seems that we could also remove the logic in determineFrameLayout relative to variable size objects because eliminateCallFramePseudoInstr could handle it, right?
