                             classes

                             are the type tags and decl tags with the kind_flag
                             set to 1.
      --btf_base=PATH        Path to the base BTF file
      --btf_encode_detached=FILENAME
                             Encode as BTF in a detached file
      --btf_encode_force     Ignore those symbols found invalid when encoding
                             BTF.

Specify supported BTF features in FEATURE_LIST or
                             'default' for default set of supported features.
                             See the pahole manual page for the list of
                             supported, default features.
