Hi Arnaldo,
<0><c>: Abbrev Number: 3 (DW_TAG_unspecified_type) <--- the problematic TAG
<1><29>: Abbrev Number: 2 (DW_TAG_subprogram) <2a> DW_AT_name : (indirect string, offset: 0x2e): entry_ibpb <2e> DW_AT_type : <0xc>
If it helps the tag is used to tell consumers like GDB that the return type of specific functions (eg entry_ibpb in the above example) is unknown. Cheers Nick
