NAME:
ABI Dumper ($CmdName)
Dump ABI of an ELF object containing DWARF debug info
DESCRIPTION:
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.
This tool is free software: you can redistribute it and/or modify it
under the terms of the GNU LGPL or GNU GPL.
USAGE:
$CmdName [options] [object]
EXAMPLES:
$CmdName libTest.so -o ABI.dump
$CmdName Module.ko.debug -o ABI.dump
INFORMATION OPTIONS:
-h|-help
Print this help.
-v|-version
Print version information.
-dumpversion
Print the tool version ($TOOL_VERSION) 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.
-readelf
Path to readelf.
-gpp
Path to g++.
-objdump
Path to objdump.
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.
