NAME
llvm-readobj - LLVM Object Reader
SYNOPSIS
llvm-readobj [options] [input...]
DESCRIPTION
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.
DIFFERENCES TO LLVM-READELF
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
\(bu 2
llvm-readelf uses GNU for the \%--elf-output-style option by default. llvm-readobj uses LLVM.
\(bu 2
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.
\(bu 2
llvm-readelf provides \%-s as an alias for \%--symbols, for GNU readelf compatibility, whereas it is an alias for \%--section-headers in llvm-readobj.
\(bu 2
llvm-readobj provides -t as an alias for \%--symbols. llvm-readelf does not.
\(bu 2
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
