DESCRIPTION

19       The GNU size utility lists the section sizes and the total size for
20       each of the binary files objfile on its argument list.  By default, one
21       line of output is generated for each file or each module if the file is
22       an archive.
23
24       objfile... are the files to be examined.  If none are specified, the
25       file "a.out" will be used instead.
26

OPTIONS

28       The command-line options have the following meanings:
29
30       -A
31       -B
32       -G
33       --format=compatibility
34           Using one of these options, you can choose whether the output from
35           GNU size resembles output from System V size (using -A, or
36           --format=sysv), or Berkeley size (using -B, or --format=berkeley).
37           The default is the one-line format similar to Berkeley's.
38           Alternatively, you can choose the GNU format output (using -G, or
39           --format=gnu), this is similar to Berkeley's output format, but
40           sizes are counted differently.
41
42           Here is an example of the Berkeley (default) format of output from
43           size:
44
45                   $ size --format=Berkeley ranlib size
46                      text    data     bss     dec     hex filename
47                    294880   81920   11592  388392   5ed28 ranlib
48                    294880   81920   11888  388688   5ee50 size
49
50           The Berkeley style output counts read only data in the "text"
51           column, not in the "data" column, the "dec" and "hex" columns both
52           display the sum of the "text", "data", and "bss" columns in decimal
53           and hexadecimal respectively.
54
55           The GNU format counts read only data in the "data" column, not the
56           "text" column, and only displays the sum of the "text", "data", and
57           "bss" columns once, in the "total" column.  The --radix option can
58           be used to change the number base for all columns.  Here is the
59           same data displayed with GNU conventions:
60
61                   $ size --format=GNU ranlib size
62                         text       data        bss      total filename
63                       279880      96920      11592     388392 ranlib
64                       279880      96920      11888     388688 size
65
66           This is the same data, but displayed closer to System V
67           conventions:
68
69                   $ size --format=SysV ranlib size
70                   ranlib  :
71                   section         size         addr
72                   .text         294880         8192
73                   .data          81920       303104
74                   .bss           11592       385024
75                   Total         388392
76
77
78                   size  :
79                   section         size         addr
80                   .text         294880         8192
81                   .data          81920       303104
82                   .bss           11888       385024
83                   Total         388688
84
85       --help
86       -h
87       -H
88       -?  Show a summary of acceptable arguments and options.
89
90       -d
91       -o
92       -x
93       --radix=number
94           Using one of these options, you can control whether the size of
95           each section is given in decimal (-d, or --radix=10); octal (-o, or
96           --radix=8); or hexadecimal (-x, or --radix=16).  In --radix=number,
97           only the three values (8, 10, 16) are supported.  The total size is
98           always given in two radices; decimal and hexadecimal for -d or -x
99           output, or octal and hexadecimal if you're using -o.
100
101       --common
102           Print total size of common symbols in each file.  When using
103           Berkeley or GNU format these are included in the bss size.
104
105       -t
106       --totals
107           Show totals of all objects listed (Berkeley or GNU format mode
108           only).
109
110       --target=bfdname
111           Specify that the object-code format for objfile is bfdname.  This
112           option may not be necessary; size can automatically recognize many
113           formats.
114
115       -v
116       -V
117       --version
118           Display the version number of size.
119
120       -f  Ignored.  This option is used by other versions of the size
121           program, but it is not supported by the GNU Binutils version.
122
123       @file
124           Read command-line options from file.  The options read are inserted
125           in place of the original @file option.  If file does not exist, or
126           cannot be read, then the option will be treated literally, and not
127           removed.
128
129           Options in file are separated by whitespace.  A whitespace
130           character may be included in an option by surrounding the entire
131           option in either single or double quotes.  Any character (including
132           a backslash) may be included by prefixing the character to be
133           included with a backslash.  The file may itself contain additional
134           @file options; any such options will be processed recursively.
