ABI Dumper (abi-dumper.pl) Dump ABI of an ELF object containing DWARF debug info


ABI Dumper is a tool for dumping ABI information of an ELF object containing DWARF debug info.

The tool is intended to be used with ABI Compliance Checker tool for tracking ABI changes of a C/C++ library or kernel module.

abi-dumper.pl libTest.so -o ABI.dump abi-dumper.pl Module.ko.debug -o ABI.dump

Information Options

-h|-help Print this help.

-v|-version Print version information.

-dumpversion Print the tool version (0.99.19) and don't do anything else.

General Options

-o|-output PATH Path to the output ABI dump file. Default: ./ABI.dump

-sort Sort data in ABI dump.

-stdout Print ABI dump to stdout.

-loud Print all warnings.

-vnum NUM Set version of the library to NUM.

-extra-info DIR Dump extra analysis info to DIR.

-bin-only Do not dump information about inline functions, pure virtual functions and non-exported global data.

-all-types Dump unused data types.

-all-symbols Dump symbols not exported by the object.

-symbols-list PATH Specify a file with a list of symbols that should be dumped.

-skip-cxx Do not dump stdc++ and gnu c++ symbols.

-all Equal to: -all-types -all-symbols.

-dump-static Dump static (local) symbols.

-compare OLD.dump NEW.dump Show added/removed symbols between two ABI dumps.

-alt PATH Path to the alternate debug info (Fedora). It is detected automatically from gnu_debugaltlink section of the input object if not specified.

-dir Show full paths of source files.

-vt-dumper PATH Path to the vtable-dumper executable if it is installed to non-default location (not in PATH).

-public-headers PATH Path to directory with public header files or to file with the list of header files. This option allows to filter out private symbols from the ABI dump.

-ignore-tags PATH Path to ignore.tags file to help ctags tool to read symbols in header files.

-reimplement-std Do nothing.

-mixed-headers This option should be specified if you are using -public-headers option and the names of public headers intersect with the internal headers.

-kernel-export Dump symbols exported by the Linux kernel and modules, i.e. symbols declared in the ksymtab section of the object and system calls.

-search-debuginfo DIR Search for debug-info files referenced from gnu_debuglink section of the object in DIR.

-keep-registers-and-offsets Dump used registers and stack offsets even if incompatible build options detected.

-quiet Do not warn about incompatible build options.

-debug Enable debug messages.

Extra Options

-use-tu-dump Use g++ -fdump-translation-unit instead of ctags to list symbols in headers. This may be useful if all functions are declared via macros in headers and ctags can't recognize them.

-include-preamble PATHS Specify header files (separated by semicolon) that should be included before others to compile without errors.

-include-paths DIRS Specify include directories (separated by semicolon) that should be passed to the compiler by -I option in order to compile headers without errors. If this option is not set then the tool will try to generate include paths automatically.

-cache-headers DIR Cache headers analysis results to reuse later.
