NAME

6       llvm-readelf - GNU-style LLVM Object Reader
7

SYNOPSIS

9       llvm-readelf [options] [input...]
10

DESCRIPTION

12       The  llvm-readelf  tool  displays low-level format-specific information
13       about one or more object files.
14
15       If input is "-", llvm-readelf reads from standard input. Otherwise,  it
16       will read from the specified filenames.
17

OPTIONS

19       --all  Equivalent  to  specifying all the main display options relevant
20              to the file format.
21
22       --addrsig
23              Display the address-significance table.
24
25       --arch-specific, -A
26              Display architecture-specific  information,  e.g.  the  ARM  at‐
27              tributes section on ARM.
28
29       --bb-addr-map
30              Display  the contents of the basic block address map section(s),
31              which contain the address of each function, along with the rela‐
32              tive offset of each basic block.
33
34       --demangle, -C
35              Display demangled symbol names in the output.
36
37       --dyn-relocations
38              Display the dynamic relocation entries.
39
40       --dyn-symbols, --dyn-syms
41              Display the dynamic symbol table.
42
43       --dynamic-table, --dynamic, -d
44              Display the dynamic table.
45
46       --cg-profile

54
55       --elf-output-style=<value>
56              Format ELF information in the specified style. Valid options are
57              LLVM and GNU. LLVM output is an expanded and structured  format,
58              whilst  GNU (the default) output mimics the equivalent GNU read‐
59              elf output.

133              of  function names and the size of their stack frames. Currently
134              only implemented for GNU style output.
135
136       --string-dump=<section[,section,...]>, -p
137              Display the specified section(s) as a list of  strings.  section
138              may be a section index or section name.
