...ir actual stack locations. In X86FrameLowering's emitCalleeSavedFrameMoves, when emitting DWARF information, this discrepancy gets fixed up by subtracting the offset reported by MFI->getObjectOffset from the minimum offset for any CSR (this is done by the "Offset = MaxOffset - Offset + saveAreaOffset;" line). Is there a reason why llvm doesn't keep around the offsets in the right order from very beginning, by pushing the CSRs in increasing order of FrameIdxs? [1]: in fact, the way X86FrameLowering's spillCalleeSavedRegisters and PEI's calculateCalleeSavedRegisters are set up,...
