DW_OP_GNU_uninit emitted with -gstrict-dwarf
Stephen Illingworth questions the emission of DW_OP_GNU_uninit when compiling with -gstrict-dwarf for the arm-none-eabi toolchain. He observed this operator in the debug information of an object file and seeks confirmation on whether this behavior is correct or if he is misusing the flag.
