NAME
       size - list section sizes and total size of binary files

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

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.

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

OPTIONS
       The command-line options have the following meanings:

       -A
       -B
       -G
       --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.  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 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
       -h
       -H
       -?  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 or GNU format these are included in the bss
	   size.

       -t
       --totals
	   Show totals of all objects listed (Berkeley or GNU format 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
       -V
       --version
	   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.

       @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.
