NAME         top

       size - list section sizes and total size of binary files

SYNOPSIS         top

       size [-A|-B|-G|--format=compatibility]
            [--target=bfdname] [-V|--version]

DESCRIPTION         top

       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.

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

OPTIONS         top

       The command-line options have the following meanings:

           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.  Alternatively, you can choose the GNU
           format output (using -G, or --format=gnu), this is similar to
           Berkeley's output format, but sizes are counted differently.

           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

           The Berkeley style output counts read only data in the "text"
           column, not in the "data" column, the "dec" and "hex" columns
           both display the sum of the "text", "data", and "bss" columns
           in decimal and hexadecimal respectively.

           The GNU format counts read only data in the "data" column,
           not the "text" column, and only displays the sum of the
           "text", "data", and "bss" columns once, in the "total"
           column.  The --radix option can be used to change the number
           base for all columns.  Here is the same data displayed with
           GNU conventions:

                   $ size --format=GNU ranlib size
                         text       data        bss      total filename
                       279880      96920      11592     388392 ranlib
                       279880      96920      11888     388688 size

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

                   $ 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

       -?  Show a summary of acceptable arguments and options.

           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.

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

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

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

           Display the version number of size.

       -f  Ignored.  This option is used by other versions of the size
           program, but it is not supported by the GNU Binutils version.

           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.
