Each line in the mapping file is of the form
<synopsis>
-testname/platformpattern=comparisonfilename
+testname:output:platformpattern=comparisonfilename
</synopsis>
The test name is just the name of the particular regression test
- module. The platform pattern is a pattern in the style of the Unix
+ module. The output value indicates which output file to check. For the
+ standard regression tests, this is always <literal>out</literal>. The
+ value corresponds to the file extension of the output file.
+ The platform pattern is a pattern in the style of the Unix
tool <command>expr</> (that is, a regular expression with an implicit
<literal>^</literal> anchor at the start). It is matched against the
platform name as printed by <command>config.guess</command>.
<quote>failure</quote> message on <systemitem>OpenBSD</systemitem>
platforms, <filename>resultmap</filename> includes:
<programlisting>
-float8/i.86-.*-openbsd=float8-small-is-zero
+float8:out:i.86-.*-openbsd=float8-small-is-zero.out
</programlisting>
which will trigger on any machine for which the output of
<command>config.guess</command> matches <literal>i.86-.*-openbsd</literal>.
