Part of https://lists.llvm.org/pipermail/llvm-dev/2021-July/151622.html "Binary utilities: switch command line parsing from llvm::cl to OptTable" * `--totals=false` and `--totals=0` cannot be used. Omit the option. * `--help-list` is removed. This is a `cl::` specific option. OptTable avoids global option collision if we decide to support multiplexing for binary utilities. Note: because the tool is simple, and its long options are uncommon, I just drop the one-dash forms except `-arch <value>` (Darwin style).

llvm-size - print size information
|
|
==================================
|
|
|
|
.. program:: llvm-size
|
|
|
|
SYNOPSIS
|
|
--------
|
|
|
|
:program:`llvm-size` [*options*] [*input...*]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
:program:`llvm-size` is a tool that prints size information for binary files.
|
|
It is intended to be a drop-in replacement for GNU's :program:`size`.
|
|
|
|
The tool prints size information for each ``input`` specified. If no input is
|
|
specified, the program prints size information for ``a.out``. If "``-``" is
|
|
specified as an input file, :program:`llvm-size` reads a file from the standard
|
|
input stream. If an input is an archive, size information will be displayed for
|
|
all its members.
|
|
|
|
OPTIONS
|
|
-------
|
|
|
|
.. option:: -A
|
|
|
|
Equivalent to :option:`--format` with a value of ``sysv``.
|
|
|
|
.. option:: --arch=<arch>
|
|
|
|
Architecture(s) from Mach-O universal binaries to display information for.
|
|
|
|
.. option:: -B
|
|
|
|
Equivalent to :option:`--format` with a value of ``berkeley``.
|
|
|
|
.. option:: --common
|
|
|
|
Include ELF common symbol sizes in bss size for ``berkeley`` output format, or
|
|
as a separate section entry for ``sysv`` output. If not specified, these
|
|
symbols are ignored.
|
|
|
|
.. option:: -d
|
|
|
|
Equivalent to :option:`--radix` with a value of ``10``.
|
|
|
|
.. option:: -l
|
|
|
|
Display verbose address and offset information for segments and sections in
|
|
Mach-O files in ``darwin`` format.
|
|
|
|
.. option:: --format=<format>
|
|
|
|
Set the output format to the ``<format>`` specified. Available ``<format>``
|
|
options are ``berkeley`` (the default), ``sysv`` and ``darwin``.
|
|
|
|
Berkeley output summarises text, data and bss sizes in each file, as shown
|
|
below for a typical pair of ELF files:
|
|
|
|
.. code-block:: console
|
|
|
|
$ llvm-size --format=berkeley test.o test2.o
|
|
text data bss dec hex filename
|
|
182 16 5 203 cb test.elf
|
|
82 8 1 91 5b test2.o
|
|
|
|
For Mach-O files, the output format is slightly different:
|
|
|
|
.. code-block:: console
|
|
|
|
$ llvm-size --format=berkeley macho.obj macho2.obj
|
|
__TEXT __DATA __OBJC others dec hex
|
|
4 8 0 0 12 c macho.obj
|
|
16 32 0 0 48 30 macho2.obj
|
|
|
|
Sysv output displays size and address information for most sections, with each
|
|
file being listed separately:
|
|
|
|
.. code-block:: console
|
|
|
|
$ llvm-size --format=sysv test.elf test2.o
|
|
test.elf :
|
|
section size addr
|
|
.eh_frame 92 2097496
|
|
.text 90 2101248
|
|
.data 16 2105344
|
|
.bss 5 2105360
|
|
.comment 209 0
|
|
Total 412
|
|
|
|
test2.o :
|
|
section size addr
|
|
.text 26 0
|
|
.data 8 0
|
|
.bss 1 0
|
|
.comment 106 0
|
|
.note.GNU-stack 0 0
|
|
.eh_frame 56 0
|
|
.llvm_addrsig 2 0
|
|
Total 199
|
|
|
|
``darwin`` format only affects Mach-O input files. If an input of a different
|
|
file format is specified, :program:`llvm-size` falls back to ``berkeley``
|
|
format. When producing ``darwin`` format, the tool displays information about
|
|
segments and sections:
|
|
|
|
.. code-block:: console
|
|
|
|
$ llvm-size --format=darwin macho.obj macho2.obj
|
|
macho.obj:
|
|
Segment : 12
|
|
Section (__TEXT, __text): 4
|
|
Section (__DATA, __data): 8
|
|
total 12
|
|
total 12
|
|
macho2.obj:
|
|
Segment : 48
|
|
Section (__TEXT, __text): 16
|
|
Section (__DATA, __data): 32
|
|
total 48
|
|
total 48
|
|
|
|
.. option:: --help, -h
|
|
|
|
Display a summary of command line options.
|
|
|
|
.. option:: -m
|
|
|
|
Equivalent to :option:`--format` with a value of ``darwin``.
|
|
|
|
.. option:: -o
|
|
|
|
Equivalent to :option:`--radix` with a value of ``8``.
|
|
|
|
.. option:: --radix=<value>
|
|
|
|
Display size information in the specified radix. Permitted values are ``8``,
|
|
``10`` (the default) and ``16`` for octal, decimal and hexadecimal output
|
|
respectively.
|
|
|
|
Example:
|
|
|
|
.. code-block:: console
|
|
|
|
$ llvm-size --radix=8 test.o
|
|
text data bss oct hex filename
|
|
0152 04 04 162 72 test.o
|
|
|
|
$ llvm-size --radix=10 test.o
|
|
text data bss dec hex filename
|
|

|
|
0x6a 0x4 0x4 114 72 test.o
|
|
|
|
.. option:: --totals, -t
|
|
|
|
Applies only to ``berkeley`` output format. Display the totals for all listed
|
|
fields, in addition to the individual file listings.
|
|
|
|
Example:
|
|
|
|
.. code-block:: console
|
|
|
|
