Standard preamble:
========================================================================

.. \*(C` and \*(C' are quotes in nroff, nothing in troff, for use with C<>.
. ds C` "" . ds C' "" 'br\} . ds C` . ds C' 'br\}
Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "SIZE 1" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
.nh size - list section sizes and total size of binary files Header "SYNOPSIS" size [-A|-B|-G|--format=compatibility] [--help] [-d|-o|-x|--radix=number] [--common] [-t|--totals] [--target=bfdname] [-V|--version] [-f] [objfile...] Header "DESCRIPTION" The GNU size utility lists the section sizes and the total size for each of the binary files objfile on its argument list. By default, one line of output is generated for each file or each module if the file is an archive.

\fIobjfile... are the files to be examined. If none are specified, the file \*(C`a.out\*(C' will be used instead.

Header "OPTIONS" The command-line options have the following meanings: Item "-A"

0

Item "-B" Item "-G" Item "--format=compatibility"

Using one of these options, you can choose whether the output from GNU \fBsize resembles output from System V size (using -A, or --format=sysv), or Berkeley size (using -B, or \fB--format=berkeley). The default is the one-line format similar to Berkeley\*(Aqs. Alternatively, you can choose the GNU format output (using -G, or --format=gnu), this is similar to Berkeley\*(Aqs output format, but sizes are counted differently. .Sp Here is an example of the Berkeley (default) format of output from \fBsize: .Sp .Vb 4 $ size --format=Berkeley ranlib size text data bss dec hex filename 294880 81920 11592 388392 5ed28 ranlib 294880 81920 11888 388688 5ee50 size .Ve .Sp The Berkeley style output counts read only data in the \*(C`text\*(C' column, not in the \*(C`data\*(C' column, the \*(C`dec\*(C' and \*(C`hex\*(C' columns both display the sum of the \*(C`text\*(C', \*(C`data\*(C', and \f(CW\*(C`bss\*(C' columns in decimal and hexadecimal respectively. .Sp The GNU format counts read only data in the \*(C`data\*(C' column, not the \*(C`text\*(C' column, and only displays the sum of the \*(C`text\*(C', \f(CW\*(C`data\*(C', and \*(C`bss\*(C' columns once, in the \*(C`total\*(C' column. The --radix option can be used to change the number base for all columns. Here is the same data displayed with GNU conventions: .Sp .Vb 4 $ size --format=GNU ranlib size text data bss total filename 279880 96920 11592 388392 ranlib 279880 96920 11888 388688 size .Ve .Sp This is the same data, but displayed closer to System V conventions: .Sp .Vb 7 $ 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 .Ve

Item "--help"

0

Item "-h" Item "-H" Item "-?"

Show a summary of acceptable arguments and options.

Item "-d"

0

Item "-o" Item "-x" Item "--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 \fB--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\*(Aqre using -o.

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

0

Item "--totals"

Show totals of all objects listed (Berkeley or GNU format mode only).

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

0

Item "-V" Item "--version"

Display the version number of size.

Item "-f" Ignored. This option is used by other versions of the size program, but it is not supported by the GNU Binutils version. Item "@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. .Sp 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. Header "SEE ALSO" \fBar\|(1), objdump\|(1), readelf\|(1), and the Info entries for binutils.
