Yes, the `DW_AT_location` was correct, so it was only the call site value that was incorrect.

In the attached test case the call site parameter entry would be printed as the following by llvm-dwardump:

  0x0000004c:       DW_TAG_GNU_call_site_parameter
                      DW_AT_location	(DW_OP_regx B0)
                      DW_AT_GNU_call_site_value	(DW_OP_GNU_entry_value(DW_OP_regx W0)

W0 has DWARF number 0, so presumably it just used the following End of Children mark for the `DW_OP_regx` operand.
