1 llvm-readelf - GNU-style LLVM Object Reader
2 ===========================================
4 .. program:: llvm-readelf
9 :program:`llvm-readelf` [*options*] [*input...*]
14 The :program:`llvm-readelf` tool displays low-level format-specific information
15 about one or more object files.
17 If ``input`` is "``-``" or omitted, :program:`llvm-readelf` reads from standard
18 input. Otherwise, it will read from the specified ``filenames``.
25 Equivalent to specifying all the main display options.
29 Display the address-significance table.
31 .. option:: --arm-attributes
33 Display the ARM attributes section. Only applicable for ARM architectures.
37 Use colors in the output for warnings and errors.
39 .. option:: --demangle, -C
41 Display demangled symbol names in the output.
43 .. option:: --dyn-relocations
45 Display the dynamic relocation entries.
47 .. option:: --dyn-symbols, --dyn-syms
49 Display the dynamic symbol table.
51 .. option:: --dynamic-table, --dynamic, -d
53 Display the dynamic table.
55 .. option:: --elf-cg-profile
57 Display the callgraph profile section.
59 .. option:: --elf-hash-histogram, --histogram, -I
61 Display a bucket list histogram for dynamic symbol hash tables.
63 .. option:: --elf-linker-options
65 Display the linker options section.
67 .. option:: --elf-output-style=<value>
69 Format ELF information in the specified style. Valid options are ``LLVM`` and
70 ``GNU``. ``LLVM`` output is an expanded and structured format, whilst ``GNU``
71 (the default) output mimics the equivalent GNU :program:`readelf` output.
73 .. option:: --elf-section-groups, --section-groups, -g
75 Display section groups.
77 .. option:: --expand-relocs
79 When used with :option:`--relocations`, display each relocation in an expanded
82 .. option:: --file-headers, -h
86 .. option:: --gnu-hash-table
88 Display the GNU hash table for dynamic symbols.
90 .. option:: --hash-symbols
92 Display the expanded hash table with dynamic symbol data.
94 .. option:: --hash-table
96 Display the hash table for dynamic symbols.
98 .. option:: --headers, -e
100 Equivalent to setting: :option:`--file-headers`, :option:`--program-headers`,
101 and :option:`--sections`.
105 Display a summary of command line options.
107 .. option:: --help-list
109 Display an uncategorized summary of command line options.
111 .. option:: --hex-dump=<section[,section,...]>, -x
113 Display the specified section(s) as hexadecimal bytes. ``section`` may be a
114 section index or section name.
116 .. option:: --needed-libs
118 Display the needed libraries.
120 .. option:: --notes, -n
124 .. option:: --program-headers, --segments, -l
126 Display the program headers.
128 .. option:: --raw-relr
130 Do not decode relocations in RELR relocation sections when displaying them.
132 .. option:: --relocations, --relocs, -r
134 Display the relocation entries in the file.
136 .. option:: --sections, --section-headers, -S
138 Display all sections.
140 .. option:: --section-data
142 When used with :option:`--sections`, display section data for each section
143 shown. This option has no effect for GNU style output.
145 .. option:: --section-mapping
147 Display the section to segment mapping.
149 .. option:: --section-relocations
151 When used with :option:`--sections`, display relocations for each section
152 shown. This option has no effect for GNU style output.
154 .. option:: --section-symbols
156 When used with :option:`--sections`, display symbols for each section shown.
157 This option has no effect for GNU style output.
159 .. option:: --stackmap
161 Display contents of the stackmap section.
163 .. option:: --stack-sizes
165 Display the contents of the stack sizes section(s), i.e. pairs of function
166 names and the size of their stack frames.
168 .. option:: --string-dump=<section[,section,...]>, -p
170 Display the specified section(s) as a list of strings. ``section`` may be a
171 section index or section name.
173 .. option:: --symbols, --syms, -s
175 Display the symbol table.
177 .. option:: --unwind, -u
179 Display unwind information.
181 .. option:: --version
183 Display the version of this program.
185 .. option:: --version-info, -V
187 Display version sections.
191 Read command-line options from response file `<FILE>`.
196 :program:`llvm-readelf` returns 0 under normal operation. It returns a non-zero
197 exit code if there were any errors.
