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 "-",	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 dif-
       ferent command-line interface and output	that is	GNU compatible.	  Fol-
       lowing is a list	of differences between llvm-readelf and	llvm-readobj:

       o llvm-readelf  uses  GNU for the --elf-output-style option by default.
	 llvm-readobj uses LLVM.

       o 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.

       o llvm-readelf provides -s as an	alias for --symbols, for  GNU  readelf
	 compatibility,	 whereas  it  is  an  alias  for  --section-headers in
	 llvm-readobj.

       o llvm-readobj provides -t as an	 alias	for  --symbols.	  llvm-readelf
	 does not.

       o 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.

GENERAL	AND MULTI-FORMAT OPTIONS
       These options are applicable to more than one file format, or are unre-
       lated to	file formats.

       --all  Equivalent  to  specifying all the main display options relevant
	      to the file format.

       --color
	      Use colors in the	output for warnings and	errors.

       --expand-relocs

	      panded multi-line	format.

       --file-headers, -h
	      Display file headers.

       --headers, -e
	      Equivalent  to  setting:	--file-headers,	--program-headers, and
	      --sections.

       --help Display a	summary	of command line	options.

       --help-list
	      Display an uncategorized summary of command line options.

       --hex-dump=<section[,section,...]>, -x

	      shown. This option has no	effect for GNU style output.

       --section-relocations, --sr

	      shown. This option has no	effect for GNU style output.

       --section-symbols, --st

	      shown.  This option has no effect	for GNU	style output.

       --stackmap
	      Display contents of the stackmap section.

       --string-dump=<section[,section,...]>, -p

ELF SPECIFIC OPTIONS
       The following options are implemented only for the ELF file format.

       --arch-specific,	-A
	      Display  architecture-specific  information,  e.g.  the  ARM at-
	      tributes section on ARM.

       --demangle, -C
	      Display demangled	symbol names in	the output.

       --dependent-libraries
