NAME         top

       abilint - validate an abigail ABI representation

       abilint parses the native XML representation of an ABI as emitted
       by abidw.  Once it has parsed the XML representation of the ABI,
       abilint builds and in-memory model from it.  It then tries to
       save it back to an XML form, to standard output.  If that
       read-write operation succeeds chances are the input XML ABI
       representation is meaningful.

       Note that the main intent of this tool to help debugging issues
       in the underlying Libabigail library.

       Note also that abilint can also read an ELF input file, build the
       in-memory model for its ABI, and serialize that model back into
       XML to standard output.  In that case, the ELF input file must be
       accompanied with its debug information in the DWARF format.

OPTIONS         top


            Annotate the ABIXML output with comments above most
            elements.  The comments are made of the pretty-printed form
            of types, declaration or even ELF symbols.  The purpose is
            to make the ABIXML output more human-readable for debugging
            or documenting purposes.

          • --ctf

            Extract ABI information from CTF debug information, if
            present in the given object.

          • --debug-info-dir <path>

            When reading an ELF input file which debug information is
            split out into a separate file, this options tells abilint
            where to find that separate debug information file.

            Note that path must point to the root directory under which
            the debug information is arranged in a tree-like manner.
            Under Red Hat based systems, that directory is usually

            Note also that this option is not mandatory for split debug
            information installed by your system's package manager
            because then abidiff knows where to find it.

          • --diff

            For XML inputs, perform a text diff between the input and
            the memory model saved back to disk.  This can help to spot
            issues in the handling of the XML format by the underlying
            Libabigail library.

          • --header-file | --hf <header-file-path>

            Specifies where to find one of the public headers of the abi
            file that the tool has to consider.  The tool will thus
            filter out types that are not defined in public headers.

          • --headers-dir | --hd <headers-directory-path-1>

            Specifies where to find the public headers of the first
            shared library that the tool has to consider.  The tool will
            thus filter out types that are not defined in public

          • --help

            Display a short help message and exits.

          • --noout

            Do not display anything on standard output.  The return code
            of the command is the only way to know if the command

          • --suppressions | suppr

            Use a suppression specification file located at
            path-to-suppression-specifications-file.  Note that this
            option can appear multiple times on the command line.  In
            that case, all of the provided suppression specification
            files are taken into account.  ABI artifacts matched by the
            suppression specifications are suppressed from the output of
            this tool.

          • --stdin | --

            Read the input content from standard input.

          • --tu

            Expect the input XML to represent a single translation unit.

          • --version | -v

            Display the version of the program and exit.
