objfile...

The GNU size utility lists the section sizesand the total sizefor 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.

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 Berkeleys.

The following 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 following example shows 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
Shows 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); in octal (-o, or --radix=8); or, in 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 youre using -o.

--target=bfdname
Specify that the object-code format for objfile is bfdname. This option may not be necessary; size can automatically recognize many formats. See Target Selection for more information.

-V
--version
Display the version number of size.
