size






size − list section sizes and total size.

     [objfile...]

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.

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









                             ‐3‐


    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.
