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.
Display a short help message and exits.
• --version | -v
Display the version of the program and exit.
• --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.
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
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
• --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
• --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.
• --stdin | --
Read the input content from standard input.
Expect the input XML to represent a single translation unit.
