.. llvm-readobj - LLVM Object Reader llvm-readobj [options] [input...] The llvm-readobj tool displays low-level format-specific information about one or more object files. If input is \(dq-\(dq, llvm-readobj reads from standard input. Otherwise, it will read from the specified filenames. llvm-readelf is an alias for the llvm-readobj tool with a slightly different command-line interface and output that is GNU compatible. Following is a list of differences between llvm-readelf and llvm-readobj: NDENT 0.0 llvm-readelf uses GNU for the \%--elf-output-style option by default. llvm-readobj uses LLVM. llvm-readelf allows single-letter grouped flags (e.g. llvm-readelf -SW is the same as llvm-readelf -S -W). llvm-readobj does not allow grouping. llvm-readelf provides \%-s as an alias for \%--symbols, for GNU readelf compatibility, whereas it is an alias for \%--section-headers in llvm-readobj. llvm-readobj provides -t as an alias for \%--symbols. llvm-readelf does not. llvm-readobj provides --sr, --sd, --st and --dt as aliases for \%--section-relocations, \%--section-data, \%--section-symbols and \%--dyn-symbols respectively. llvm-readelf does not provide these aliases, to avoid conflicting with grouped flags. NINDENT These options are applicable to more than one file format, or are unrelated to file formats. NDENT 0.0
