=head1 SYNOPSIS
|
|
|
|
compareSumTests3 -- Two-way or three-way compare between DejaGNU .sum files
|
|
|
|
=head1 USAGE
|
|
|
|
compareSumTests3 old1.sum [old2.sum] new.sum
|
|
compareSumTests3 -i 1:2 -x 2:3 old1.sum old2.sum new.sum
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Gives results in terms of 'new' (e.g. things that work in 'new' and don't in
|
|
other compilers are improvements, things that don't in 'new' and do in others
|
|
are regressions, and it tells you which of the two old compilers (or both)
|
|
the test is a regression from.
|
|
|
|
We treat any DG result other than PASS or XFAIL as a failure, e.g.
|
|
UNRESOLVED, UNTESTED or test was not run.
|
|
|
|
We merge some tests into 'logical tests' with multiple subphases.
|
|
For instance, some tests will have compile, execute, and link
|
|
subtests. For these tests, if one of the phases fails, we
|
|
indicate which phase the failure originates in. For instance,
|
|
in the following test results:
|
|
|
|
gcc.c-torture/compile_execute/xxxx.c: [FAIL:C,FAIL:X,PASS]
|
|
|
|
the "compile_execute" replaces the compile or execute portion of the test name,
|
|
and "FAIL:C" and "FAIL:X" indicates where the combined test failed.

=head1 OPTIONS
|
|
|
|
=head2 OVERVIEW
|
|
|
|
=over 4
|
|
|
|
=item *
|
|
|
|
C<-i X:Y>: Only display differences between the two indicated runs.
|
|
|
|
=item *
|
|
|
|
C<-p>: Give plain output, suitable for piping to another program.
|
|
|
|
=item *
|
|
|
|
C<-x X:Y>: Exclude differences between the two indicated runs.
|
|
|
|
=back
|
|
|
|
=head2 PLAIN OUTPUT FORMAT
|
|
|
|
In the plain
|
|
output format, the category headers are not displayed and there are no tabs
|
|
in front of each result line. Instead, each result line has two characters
|
|
followed by a space in front of it. The first character will be either an 'I'
|
|
for improvement or 'R' for regression; the second character will be a 1, 2, or 3,
|
|
indicating which run was the odd one out.
|
|
|
|
=head2 SELECTING CHANGE SUBSETS
|
|
|
|
The following options cause only a selected subset of changes to be displayed.
|
|
These options ask for a "run", a number which is used to select
|
|
one of the three runs (C<old1>, C<old2>, or C<new>.) C<1> and C<2> signify C<old1> and C<old2>
|
|
respectively; 3 signifies C<new>. If multiple options are given, the changes displayed
|
|
will be those which obey all of the given restrictions.
|
|
|
|
Typical usage of these options is to express something like "give me all changes
|
|
between 2 and 3, except for those where there was the same difference betwen 1 and 2
|
|
(as between 2 and 3.)" This would be given as:
|
|
|
|
-i 2:3 -x 1:2
|
|
|
|
=over 4
|
|
|
|
=item *
|
|
|
|
C<-i X:Y>: Only differences which are present between the two runs given
|
|
are displayed. For instance, if C<-i 1:2> is given and test A passes in
|
|
runs 1 and 2 but fails in run 3, that result will not be displayed.
|
|
|
|
=item *
|
|
|
|
C<-x X:Y>: Differences which are identical to a difference between the two runs
|
|
given will B<not> be displayed. For instance, if C<-x 1:2> is given and
|
|
test A passes in run 1 and fails in runs 2 and 3, that result will not be
|
|
displayed (since C<-x> will cause the difference between 1 and 2 to be ignored,
|
|
and the difference in 1 and 3 parallels the difference between 1 and 2.)
|
|
This option may only be used in conjunction with C<-i>.
