gcc dwarf DW_OP_mod

[phi gcc]

Hi All,

In vmlinux dwarf debug info I can see this that was generacted by gcc

DW_OP_breg6 (rbp): -52;
DW_OP_deref_size: 4;
DW_OP_breg6 (rbp): -56;
DW_OP_deref_size: 4;
DW_OP_GNU_convert <0x41f117f>;
DW_OP_breg6 (rbp): -60;
DW_OP_deref_size: 4;
DW_OP_GNU_convert <0x41f117f>;
DW_OP_div;
DW_OP_GNU_convert <0x0>;
DW_OP_mod

I am not familiar with DW_OP_GNU_convert <0x0>; My feeling is that is
convert this to an integer ? that should be zero.

If so the question is, does generating a mod 0 is intentional ?

Any help appreciated.

There is still a possibilility that the convert don't give ZERO whin
then would mean the MOD is ok.

Cheers,
Phi
