137 .SH "DESCRIPTION"
138 .IX Header "DESCRIPTION"
139 \&\fBranlib\fR generates an index to the contents of an archive and
140 stores it in the archive. The index lists each symbol defined by a
141 member of an archive that is a relocatable object file.
142 .PP
143 You may use \fBnm \-s\fR or \fBnm \-\-print\-armap\fR to list this index.
144 .PP
145 An archive with such an index speeds up linking to the library and
146 allows routines in the library to call each other without regard to
147 their placement in the archive.
148 .PP
149 The \s-1GNU\s0 \fBranlib\fR program is another form of \s-1GNU\s0 \fBar\fR; running
150 \&\fBranlib\fR is completely equivalent to executing \fBar \-s\fR.

173 Operate in \fIdeterministic\fR mode. The symbol map archive member's
174 header will show zero for the \s-1UID\s0, \s-1GID\s0, and timestamp. When this
175 option is used, multiple runs will produce identical output files.
176 .Sp
177 If \fIbinutils\fR was configured with
178 \&\fB\-\-enable\-deterministic\-archives\fR, then this mode is on by
179 default. It can be disabled with the \fB\-U\fR option, described
180 below.
181 .IP "\fB\-t\fR" 4
182 .IX Item "-t"
183 Update the timestamp of the symbol map of an archive.
184 .IP "\fB\-U\fR" 4
185 .IX Item "-U"
186 Do \fInot\fR operate in \fIdeterministic\fR mode. This is the
187 inverse of the \fB\-D\fR option, above: the archive index will get
188 actual \s-1UID\s0, \s-1GID\s0, timestamp, and file mode values.
189 .Sp
190 If \fIbinutils\fR was configured \fIwithout\fR
191 \&\fB\-\-enable\-deterministic\-archives\fR, then this mode is on by
192 default.
193 .IP "\fB@\fR\fIfile\fR" 4
194 .IX Item "@file"
195 Read command-line options from \fIfile\fR. The options read are
196 inserted in place of the original @\fIfile\fR option. If \fIfile\fR
197 does not exist, or cannot be read, then the option will be treated
198 literally, and not removed.
199 .Sp
200 Options in \fIfile\fR are separated by whitespace. A whitespace
201 character may be included in an option by surrounding the entire
202 option in either single or double quotes. Any character (including a
203 backslash) may be included by prefixing the character to be included
204 with a backslash. The \fIfile\fR may itself contain additional
205 @\fIfile\fR options; any such options will be processed recursively.
