18 The GNU size utility lists the section sizes and the total size for
19 each of the binary files objfile on its argument list. By default, one
20 line of output is generated for each file or each module if the file is
21 an archive.
22 objfile... are the files to be examined. If none are specified, the
24 file "a.out" will be used instead.
25
27 The command-line options have the following meanings:
28 -A
30 -B
31 -G
32 --format=compatibility
33 Using one of these options, you can choose whether the output from
34 GNU size resembles output from System V size (using -A, or
35 --format=sysv), or Berkeley size (using -B, or --format=berkeley).
36 The default is the one-line format similar to Berkeley's.
37 Alternatively, you can choose the GNU format output (using -G, or
38 --format=gnu), this is similar to Berkeley's output format, but
39 sizes are counted differently.
40 Here is an example of the Berkeley (default) format of output from
42 size:
43 $ size --format=Berkeley ranlib size
45 text data bss dec hex filename
46 294880 81920 11592 388392 5ed28 ranlib
47 294880 81920 11888 388688 5ee50 size
48 The Berkeley style output counts read only data in the "text"
50 column, not in the "data" column, the "dec" and "hex" columns both
51 display the sum of the "text", "data", and "bss" columns in decimal
52 and hexadecimal respectively.
53 The GNU format counts read only data in the "data" column, not the
55 "text" column, and only displays the sum of the "text", "data", and
56 "bss" columns once, in the "total" column. The --radix option can
57 be used to change the number base for all columns. Here is the
58 same data displayed with GNU conventions:
59 $ size --format=GNU ranlib size
61 text data bss total filename
62 279880 96920 11592 388392 ranlib
63 279880 96920 11888 388688 size
64 This is the same data, but displayed closer to System V
66 conventions:
67 $ size --format=SysV ranlib size
69 ranlib :
70 section size addr
71 .text 294880 8192
72 .data 81920 303104
73 .bss 11592 385024
74 Total 388392
75 size :
78 section size addr
79 .text 294880 8192
80 .data 81920 303104
81 .bss 11888 385024
82 Total 388688
83 --help
85 Show a summary of acceptable arguments and options.
86 -d
88 -o
89 -x
90 --radix=number
91 Using one of these options, you can control whether the size of
92 each section is given in decimal (-d, or --radix=10); octal (-o, or
93 --radix=8); or hexadecimal (-x, or --radix=16). In --radix=number,
94 only the three values (8, 10, 16) are supported. The total size is
95 always given in two radices; decimal and hexadecimal for -d or -x
96 output, or octal and hexadecimal if you're using -o.
97 --common
99 Print total size of common symbols in each file. When using
100 Berkeley or GNU format these are included in the bss size.
101 -t
103 --totals
104 Show totals of all objects listed (Berkeley or GNU format mode
105 only).
106 --target=bfdname
108 Specify that the object-code format for objfile is bfdname. This
109 option may not be necessary; size can automatically recognize many
110 formats.
111 -V
113 --version
114 Display the version number of size.
115 @file
117 Read command-line options from file. The options read are inserted
118 in place of the original @file option. If file does not exist, or
119 cannot be read, then the option will be treated literally, and not
120 removed.
121 Options in file are separated by whitespace. A whitespace
123 character may be included in an option by surrounding the entire
124 option in either single or double quotes. Any character (including
125 a backslash) may be included by prefixing the character to be
126 included with a backslash. The file may itself contain additional
127 @file options; any such options will be processed recursively.
