--- Comment #2 from LU Hongyi <hluaw at connect dot ust.hk> --- Oh, sorry I didn't read the standard carefully. But still, the code generated by GCC still looks a bit strange. There is a DW_OP_const2u between two composite location descriptor. The final DWARF generated by GCC is actually ``` DW_OP_const4u: 338810; DW_OP_stack_value; DW_OP_bit_piece: size: 25 offset: 0; DW_OP_bit_piece: size: 39 offset: 0 ``` where two DW_OP_bit_piece stacks side-by-side, but the standard specifies that it should each of them should preceding a single location? Perhaps that causes LLDB broken. I presume the correct should be: ``` DW_OP_const4u: 338810; DW_OP_stack_value; DW_OP_const2u: 4728 DW_OP_bit_piece: size: 25 offset: 0; DW_OP_bit_piece: size: 39 offset: 0 ```
