llvm-objdump - LLVM’s object file dumper

SYNOPSIS

llvm-objdump [commands] [options] [filenames…]

DESCRIPTION

The llvm-objdump utility prints the contents of object files and final linked images named on the command line. If no file name is specified, llvm-objdump will attempt to read from a.out. If - is used as a file name, llvm-objdump will process a file on its standard input stream.

COMMANDS

At least one of the following commands are required, and some commands can be combined with other commands:

-a, --archive-headers

Display the information contained within an archive’s headers.

-d, --disassemble

Disassemble all executable sections found in the input files. On some architectures (AArch64, PowerPC, x86), all known instructions are disassembled by default. On the others, --mcpu or --mattr is needed to enable some instruction sets. Disabled instructions are displayed as <unknown>.

-D, --disassemble-all

Disassemble all sections found in the input files.

--disassemble-symbols=<symbol1[,symbol2,...]>

Disassemble only the specified symbols. Takes demangled symbol names when --demangle is specified, otherwise takes mangled symbol names. Implies --disassemble.

Each argument is split on commas. To select a symbol whose name contains commas, use --disassemble with a symbol argument instead.

--disassemble=<symbol>

Disassemble only the specified symbol. Takes a demangled symbol name when --demangle is specified, otherwise takes a mangled symbol name. Implies --disassemble.

The argument is a single symbol name. To select multiple symbols, specify this option multiple times or use --disassemble-symbols.

--dwarf=<value>

Dump the specified DWARF debug sections. The supported values are:

frames - .debug_frame

-f, --file-headers

Display the contents of the overall file header.

--fault-map-section

Display the content of the fault map section.

-h, --headers
