     size - list section sizes and total size.

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

     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:

         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

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

GNU Development Tools                                     SIZE(1)

                 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 format these are included in the bss

         Show totals of all objects listed (Berkeley format
         listing 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.

         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
