[LLVMdev] Debug with DW_OP_piece and DW_OP_bit_piece

[Villmow, Micah]

We are running into trouble with debug information in that we have registers along with sub registers, and they both point to the same dwarf register. Does LLVM support the DW_OP_piece/bit_piece debug information when allocating a sub-register from a super register? If not, is there any plan to add it? If not, would it be difficult to add?

Thanks,
Micah
