PROGRAM:

NAME

size - list section sizes and total size.

SYNOPSIS

size [-A|-B|--format=compatibility]
[--help]
[-d|-o|-x|--radix=number]
[--common]
[-t|--totals]
[--target=bfdname] [-V|--version]
[objfile...]

DESCRIPTION

The GNU size utility lists the section sizes---and the total size---for each of the object
or archive files objfile in its argument list. By default, one line of output is
generated for each object file or each module in an archive.

objfile... are the object files to be examined. If none are specified, the file "a.out"
will be used.

OPTIONS

The command line options have the following meanings:

-A
-B
--format=compatibility
Using one of these options, you can choose whether the output from GNU size resembles
output from System V size (using -A, or --format=sysv), or Berkeley size (using -B, or
--format=berkeley). The default is the one-line format similar to Berkeley's.

Here is an example of the Berkeley (default) format of output from size:

$ size --format=Berkeley ranlib size
text data bss dec hex filename
294880 81920 11592 388392 5ed28 ranlib
294880 81920 11888 388688 5ee50 size

This is the same data, but displayed closer to System V conventions:

$ size --format=SysV ranlib size
ranlib :
section size addr
.text 294880 8192
.data 81920 303104
.bss 11592 385024
Total 388392

size :
section size addr
.text 294880 8192
.data 81920 303104
.bss 11888 385024
Total 388688

--help
Show a summary of acceptable arguments and options.

-d
-o
-x
--radix=number
Using one of these options, you can control whether the size of each section is given
in decimal (-d, or --radix=10); octal (-o, or --radix=8); or hexadecimal (-x, or
--radix=16). In --radix=number, only the three values (8, 10, 16) are supported. The
total size is always given in two radices; decimal and hexadecimal for -d or -x
output, or octal and hexadecimal if you're using -o.

--common
Print total size of common symbols in each file. When using Berkeley format these are
included in the bss size.

-t
--totals
Show totals of all objects listed (Berkeley format listing mode only).

--target=bfdname
Specify that the object-code format for objfile is bfdname. This option may not be
necessary; size can automatically recognize many formats.

-V
--version
Display the version number of size.

@file
Read command-line options from file. The options read are inserted in place of the
original @file option. If file does not exist, or cannot be read, then the option
will be treated literally, and not removed.

Options in file are separated by whitespace. A whitespace character may be included
in an option by surrounding the entire option in either single or double quotes. Any
character (including a backslash) may be included by prefixing the character to be
included with a backslash. The file may itself contain additional @file options; any
such options will be processed recursively.
