llvm-readelf - GNU-style LLVM Object Reader

:::{program} llvm-readelf :::

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

::::{option} –addrsig Display the address-significance table.

:::{option} –all, -a :::

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

:::{option} –arch-specific, -A Display architecture-specific information, e.g. the ARM attributes section on ARM. :::

:::{option} –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. :::

:::{option} –call-graph-info Display the call graph section entries i.e. for each function its identifying information, each of its direct callees’ information and for each indirect callee a 64-bit number representing the callee’s function signature. This information can be used to reconstruct the program call graph. The output format is described in .llvm.callgraph Section Layout. :::

:::{option} –cg-profile Display the callgraph profile section. :::

:::{option} –decompress, -z Dump decompressed section content when used with -x or -p. If the section(s) are not compressed, they are displayed as is. :::

:::{option} –demangle, -C Display demangled symbol names in the output. :::

:::{option} –dependent-libraries Display the dependent libraries section. :::

:::{option} –dynamic-table, –dynamic, -d Display the dynamic table. :::

:::{option} –dyn-relocations Display the dynamic relocation entries. :::

:::{option} –dyn-symbols, –dyn-syms Display the dynamic symbol table. :::

:::{option} –elf-linker-options Display the linker options section. :::

:::{option} –elf-output-style= Format ELF information in the specified style. Valid options are LLVM, GNU, and JSON. 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. :::

:::{option} –extra-sym-info Display extra information (section name) when showing symbols. :::

:::{option} –expand-relocs When used with --relocations, display each relocation in an expanded multi-line format. :::

:::{option} –file-header, -h Display file headers. :::

:::{option} –gnu-hash-table Display the GNU hash table for dynamic symbols. :::

:::{option} –hash-symbols Display the expanded hash table with dynamic symbol data. :::

:::{option} –hash-table Display the hash table for dynamic symbols. :::

:::{option} –headers, -e Equivalent to setting: --file-header, --program-headers, and --sections. :::

:::{option} –help Display a summary of command line options. :::

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

:::{option} –histogram, -I Display a bucket list histogram for dynamic symbol hash tables. :::

:::{option} –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. :::

:::{option} –needed-libs Display the needed libraries. :::

:::{option} –no-demangle Do not display demangled symbol names in the output. On by default. :::

:::{option} –notes, -n Display all notes. :::

:::{option} –offloading Display list of HIP offload bundles. :::

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

:::{option} –program-headers, –segments, -l Display the program headers. :::

:::{option} –relocations, –relocs, -r Display the relocation entries in the file. :::

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

:::{option} –section-details, -t Display all section details. Used as an alternative to --sections. :::

:::{option} –section-groups, -g Display section groups. :::

:::{option} –section-mapping Display the section to segment mapping. :::

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

:::{option} –sections, –section-headers, -S Display all sections. :::

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

:::{option} –stackmap Display contents of the stackmap section. :::

:::{option} –stack-sizes Display the contents of the stack sizes section(s), i.e. pairs of function names and the size of their stack frames. In LLVM and JSON output (see --elf-output-style), each entry in a linked file also includes the function’s address. :::

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

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

:::{option} –unwind, -u Display unwind information. :::

:::{option} –version Display the version of the llvm-readelf executable. :::

:::{option} –version-info, -V Display version sections. :::

:::{option} –wide, -W Ignored for GNU readelf compatibility. The output is already similar to when using -W with GNU readelf. :::

:::{option} @ 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.
