llvm-readelf - GNU-style LLVM Object Reader¶
SYNOPSIS¶
llvm-readelf [options] [input…]
DESCRIPTION¶
The llvm-readelf tool displays low-level format-specific information about one or more object files.
If input
is “-
”, llvm-readelf reads from standard
input. Otherwise, it will read from the specified filenames
.
OPTIONS¶
- --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
, andJSON
.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.
- --extra-sym-info¶
Display extra information (section name) when showing symbols.
- --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--sections
.
- --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.
- --memtag¶
Display information about memory tagging present in the binary. This includes various memtag-specific dynamic entries, decoded global descriptor sections, and decoded Android-specific ELF notes.
- --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
--sections
.
- --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>.
EXIT STATUS¶
llvm-readelf returns 0 under normal operation. It returns a non-zero exit code if there were any errors.
