llvm-readelf - GNU-style LLVM Object Reader

SYNOPSIS DESCRIPTION OPTIONS EXIT STATUS SEE ALSO AUTHOR COPYRIGHT

llvm-readelf [options] [input...]

The llvm-readelf tool displays low-level format-specific information about one or more object files.

If input is dq-dq, llvm-readelf reads from standard input. Otherwise, it will read from the specified filenamesamp;.

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

--addrsig
	Display the address-significance table.

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

--bb-addr-map
	Display the contents of the basic block address map section(s), which contain the address of each function, along with the relative offset of each basic block.

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

--dependent-libraries
	Display the dependent libraries section.

--dyn-relocations
	Display the dynamic relocation entries.

--dyn-symbols, --dyn-syms
	Display the dynamic symbol table.

--dynamic-table, --dynamic, -d
	Display the dynamic table.

--cg-profile
	Display the callgraph profile section.

--histogram, -I
	Display a bucket list histogram for dynamic symbol hash tables.

--elf-linker-options
	Display the linker options section.

--elf-output-style=<value>
	Format ELF information in the specified style. Valid options are LLVM, GNU, and JSONamp;. LLVM output is an expanded and structured format. GNU (the default) output mimics the equivalent GNU readelf output. JSON is JSON formatted output intended for machine consumption.

--section-groups, -g
	Display section groups.

--expand-relocs
	When used with  --relocations, display each relocation in an expanded multi-line format.

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

--gnu-hash-table
	Display the GNU hash table for dynamic symbols.

--hash-symbols
	Display the expanded hash table with dynamic symbol data.

--hash-table
	Display the hash table for dynamic symbols.

--headers, -e
	Equivalent to setting:  --file-header,  --program-headers, and  --sectionsamp;.

--help	Display a summary of command line options.

--hex-dump=<section[,section,...]>, -x
	Display the specified section(s) as hexadecimal bytes. section may be a section index or section name.

--needed-libs
	Display the needed libraries.

--no-demangle
	Do not display demangled symbol names in the output. On by default.

--notes, -n
	Display all notes.

--pretty-print
	When used with  --elf-output-style, JSON output will be formatted in a more readable format.

--program-headers, --segments, -l
	Display the program headers.

--raw-relr
	Do not decode relocations in RELR relocation sections when displaying them.

--relocations, --relocs, -r
	Display the relocation entries in the file.

--sections, --section-headers, -S
	Display all sections.

--section-data
	When used with  --sections, display section data for each section shown. This option has no effect for GNU style output.

--section-details, -t
	Display all section details. Used as an alternative to  --sectionsamp;.

--section-mapping
	Display the section to segment mapping.

--section-relocations
	When used with  --sections, display relocations for each section shown. This option has no effect for GNU style output.

--section-symbols
	When used with  --sections, display symbols for each section shown. This option has no effect for GNU style output.

--stackmap
	Display contents of the stackmap section.

--stack-sizes
	Display the contents of the stack sizes section(s), i.e. pairs of function names and the size of their stack frames. Currently only implemented for GNU style output.

--string-dump=<section[,section,...]>, -p
	Display the specified section(s) as a list of strings. section may be a section index or section name.

--symbols, --syms, -s
	Display the symbol table. Also display the dynamic symbol table when using GNU output style for ELF.

--unwind, -u
	Display unwind information.

--version
	Display the version of the llvm-readelf executable.

--version-info, -V
	Display version sections.

--wide, -W	Ignored for GNU readelf compatibility. The output is already similar to when using -W with GNU readelf.

@<FILE>	Read command-line options from response file <FILE>amp;.

llvm-readelf returns 0 under normal operation. It returns a non-zero exit code if there were any errors.
