6 llvm-objdump - LLVM's object file dumper
7
9 llvm-objdump [commands] [options] [filenames...]
10
12 The llvm-objdump utility prints the contents of object files and final
13 linked images named on the command line. If no file name is specified,
14 llvm-objdump will attempt to read from a.out. If - is used as a file
15 name, llvm-objdump will process a file on its standard input stream.
16
18 At least one of the following commands are required, and some commands
19 can be combined with other commands:
20 -a, --archive-headers
22 Display the information contained within an archive's headers.
23 -d, --disassemble
25 Disassemble all text sections found in the input files.
26 -D, --disassemble-all
28 Disassemble all sections found in the input files.
29 --disassemble-functions=<symbol1[,symbol2,...]>
31 Disassemble only the specified symbols. Takes demangled symbol
32 names when --demangle is specified, otherwise takes mangled sym‐
33 bol names. Implies --disassemble.
34 --dwarf=<value>
36 Dump the specified DWARF debug sections. The supported values
37 are:
38 frames - .debug_frame
40 -f, --file-headers

45 Display the content of the fault map section.
46 -h, --headers, --section-headers

75 Display the version of the llvm-objdump executable. Does not
76 stack with other commands.
77 -x, --all-headers
79 Display all available header information. Equivalent to specify‐
80 ing --archive-headers, --file-headers, --private-headers,
81 --reloc, --section-headers, and --syms.
82
84 llvm-objdump supports the following options:
85 --adjust-vma=<offset>
87 Increase the displayed address in disassembly or section header
88 printing by the specified offset.
89 --arch-name=<string>
91 Specify the target architecture when disassembling. Use
92 --version for a list of available targets.
93 -C, --demangle
95 Demangle symbol names in the output.
96 -j, --section=<section1[,section2,...]>
98 Perform commands on the specified sections only. For Mach-O use
99 segment,section to specify the section name.
100 -l, --line-numbers
102 When disassembling, display source line numbers. Implies
103 --disassemble.
104 -M, --disassembler-options=<opt1[,opt2,...]>
106 Pass target-specific disassembler options. Currently supported
107 for ARM targets only. Available options are reg-names-std and
108 reg-names-raw.
109 --mcpu=<cpu-name>
111 Target a specific CPU type for disassembly. Specify --mcpu=help
112 to display available CPUs.
113 --mattr=<a1,+a2,-a3,...>
115 Enable/disable target-specific attributes. Specify --mcpu=help
116 to display the available attributes.

119 When disassembling, do not print leading addresses.
120 --no-show-raw-insn
122 When disassembling, do not print the raw bytes of each instruc‐
123 tion.

126 Use hex format when printing immediate values in disassembly
127 output.

130 When disassembling, display source interleaved with the disas‐
131 sembly. Implies --disassemble.
