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
21 -a, --archive-headers
22 Display the information contained within an archive's headers.
23

27 -D, --disassemble-all
28 Disassemble all sections found in the input files.
29
30 --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
35 --dwarf=<value>
36 Dump the specified DWARF debug sections. The supported values
37 are:
