# Object file size

The object file size utility lists the sizes of ELF sections (and optionally the total size) in the specified files. The files can be object files, archive files, or core dumps.

If no input files are specified, the utility attempts to read from `a.out`.

Note

This utility returns zero on success, or greater than zero if an error occurs.

## Command

To start the object file size utility from the command line:

hexagon-size [<option...>] [<file...>]
    Copy to clipboard

Where `<option>` is one or more of the following:

--format=<format>
    -A
    -B
    --help    | -h
    --radix=<radix>
    -d
    -o
    -x
    --version | -V
    Copy to clipboard

## Options

--format=<format>
    Copy to clipboard

Display the output using the specified format (System V or Berkeley). Possible values are `sysv` and `berkeley` (default).

For more information on the display formats, see  [Output formats](https://docs.qualcomm.com/doc/80-N3040-23/topic/object-file-size.html#hu-obj-file-size-output-formats).

-A
    Copy to clipboard

Equivalent to `--format=sysv`.

-B
    Copy to clipboard

Equivalent to `--format=berkeley`.

--help
    -h
    Copy to clipboard

Display command usage information and then exit.

--radix=<radix>
    Copy to clipboard

Display numeric values using the specified radix. The possible values are 8, 10, or 16. The default value is 10.

-o
    Copy to clipboard

Equivalent to `--radix=8`.

-d
    Copy to clipboard

Equivalent to `--radix=10`.

-x
    
    Equivalent to ``--radix=16``.
    Copy to clipboard

--version
    -V
    Copy to clipboard

Display the utility version identifier and then exit.

## Output formats

The object file size utility can display its output in one of two formats: Berkeley-style or System V-style.

### Berkeley-style output

Berkeley-style output consists of an initial header line (labeling the individual fields), followed by one line of output for each ELF object that is either specified directly on the command line or is contained in a specified archive.

Each line contain the following fields:

- Size of the `text` segment in the object
- Size of the `data` segment in the object
- Size of the `bss` segment in the object
- Total size of the object, in decimal or octal format

    - Decimal is used if the specified output radix for numeric values is 10 or 16
    - Octal is used if the radix is 8
- Total size of the object, in hexadecimal format
- Name of the object file

If `--totals` is specified, the output includes an additional line (in the same format) that contains the sum of the respective fields. The file name field for this line contains the string, (`TOTALS`).

### System V-style output

System V-style output consists of the following information for each ELF object that is either specified directly on the command line or is contained in a specified archive:

- Name of the object followed by a colon character.
- One header line containing the field labels for the subsequent lines.
- One line for each section contained in the object. Each line has three fields:

    - Section name
    - Section size in the specified radix
    - Section address in the selected radix
- An additional line with the section name set to `Total`, and a `size` field set to the sum of all the reported section sizes.

## Examples

Section sizes for `/bin/ls`:

$ hexagon-size /bin/ls
    text       data       bss        dec        hex        filename
    20975      540        392        21907      5593        /bin/ls
    Copy to clipboard

Sizes and total for `/bin/ls` and `/bin/dd` in hexadecimal:

$ hexagon-size -tx /bin/ls /bin/dd
    text       data       bss        dec        hex        filename
    0x51ef     0x21c      0x188      21907      5593        /bin/ls
    0x3df5     0x170      0x200      16741      4165        /bin/dd
    0x8fe4     0x38c      0x388      38648      96f8       (TOTALS)
    Copy to clipboard

Section sizes for `/bin/ls` in System V format:

$ hexagon-size -A /bin/ls
    /bin/ls  :
    section            size       addr
