The idea is + that for a centralized testing lab where people have to share a + target between multiple developers. There are settings for both + remote targets and remote hosts. Here's an example of a Master + Config File (also called the Global config file) for a + <I +CLASS="EMPHASIS" +>canadian cross</I +>. A canadian cross is when + you build and test a cross compiler on a machine other than the + one it's to be hosted on.</P +><P +>Here we have the config settings for our California + office. Note that all config values are site dependant. Here we + have two sets of values that we use for testing m68k-aout cross + compilers. As both of these target boards has a different + debugging protocol, we test on both of them in sequence.</P +><DIV +CLASS="EXAMPLE" +><A +NAME="AEN921" +></A +><P +><B +>Example 4.

The simple settings, like for + <I +CLASS="EMPHASIS" +>sparc64-elf</I +> only require setting the name of + the single board config file. The <I +CLASS="EMPHASIS" +>mips-elf</I +> + target is more complicated. Here it sets the list to three target + boards. One is the default mips target, and both + <I +CLASS="EMPHASIS" +>wilma</I +> <I +CLASS="EMPHASIS" +>barney</I +> are + symbolic names for other mips boards. Symbolic names are covered + in the <A +HREF="x1214.html" +>Adding A New Board</A +> chapter. The more complicated + example is the one for <I +CLASS="EMPHASIS" +>mips-lsi-elf</I +>. This one + runs the tests with multiple iterations using all possible + combinations of the <TT +CLASS="OPTION" +>--soft-float</TT +> and the + <TT +CLASS="OPTION" +>--el</TT +> (little endian) option. Needless to say, + this last feature is mostly compiler specific.</P +></DIV +><DIV +CLASS="NAVFOOTER" +><HR +ALIGN="LEFT" +WIDTH="100%"><TABLE +SUMMARY="Footer navigation table" +WIDTH="100%" +BORDER="0" +CELLPADDING="0" +CELLSPACING="0" +><TR +><TD +WIDTH="33%" +ALIGN="left" +VALIGN="top" +><A +HREF="c848.html" +ACCESSKEY="P" +><<< Previous</A +></TD +><TD +WIDTH="34%" +ALIGN="center" +VALIGN="top" +><A +HREF="book1.html" +ACCESSKEY="H" +>Home</A +></TD +><TD +WIDTH="33%" +ALIGN="right" +VALIGN="top" +><A +HREF="x935.html" +ACCESSKEY="N" +>Next >>></A +></TD +></TR +><TR +><TD +WIDTH="33%" +ALIGN="left" +VALIGN="top" +>Customizing DejaGnu</TD +><TD +WIDTH="34%" +ALIGN="center" +VALIGN="top" +><A +HREF="c848.html" +ACCESSKEY="U" +>Up</A +></TD +><TD +WIDTH="33%" +ALIGN="right" +VALIGN="top" +>Board Config File</TD +></TR +></TABLE +></DIV +></BODY +></HTML +>
