=head1 SYNOPSIS

31
compareSumTests3 -- Two-way or three-way compare between DejaGNU .sum files
32
 
33
=head1 USAGE
34
 
35
        compareSumTests3 old1.sum [old2.sum] new.sum
36
        compareSumTests3 -i 1:2 -x 2:3 old1.sum old2.sum new.sum

=head1 DESCRIPTION
39
 
40
Gives results in terms of 'new' (e.g. things that work in 'new' and don't in
41
other compilers are improvements, things that don't in 'new' and do in others
42
are regressions, and it tells you which of the two old compilers (or both)
43
the test is a regression from.
44
 
45
We treat any DG result other than PASS or XFAIL as a failure, e.g.
46
UNRESOLVED, UNTESTED or test was not run.
47
 
48
We merge some tests into 'logical tests' with multiple subphases.
49
For instance, some tests will have compile, execute, and link
50
subtests.  For these tests, if one of the phases fails, we
51
indicate which phase the failure originates in.  For instance,
52
in the following test results:
53
 
54
        gcc.c-torture/compile_execute/xxxx.c: [FAIL:C,FAIL:X,PASS]
55
 
56
the "compile_execute" replaces the compile or execute portion of the test name,
57
and "FAIL:C" and "FAIL:X" indicates where the combined test failed.

61
=head2 OVERVIEW
62
 
63
=over 4
64
 
65
=item *
66
 
67
C<-i X:Y>: Only display differences between the two indicated runs.
68
 
69
=item *
70
 
71
C<-p>: Give plain output, suitable for piping to another program.
72
 
73
=item *
74
 
75
C<-x X:Y>: Exclude differences between the two indicated runs.
76
 
77

78
 
79
=head2 PLAIN OUTPUT FORMAT
80
 
81
In the plain
82
output format, the category headers are not displayed and there are no tabs
83
in front of each result line.  Instead, each result line has two characters
84
followed by a space in front of it.  The first character will be either an 'I'
85
for improvement or 'R' for regression; the second character will be a 1, 2, or 3,
86
indicating which run was the odd one out.
87
 
88
=head2 SELECTING CHANGE SUBSETS
89
 
90
The following options cause only a selected subset of changes to be displayed.
91
These options ask for a "run", a number which is used to select
92
one of the three runs (C, C, or C.)  C<1> and C<2> signify C and C
93
respectively; 3 signifies C. If multiple options are given, the changes displayed
94
will be those which obey all of the given restrictions.
95
 
96
Typical usage of these options is to express something like "give me all changes
97
between 2 and 3, except for those where there was the same difference betwen 1 and 2
98
(as between 2 and 3.)"  This would be given as:
99
 
100
        -i 2:3 -x 1:2
101
 
102
=over 4
103
 
104
=item *
105
 
106
C<-i X:Y>: Only differences which are present between the two runs given
107
are displayed. For instance, if C<-i 1:2> is given and test A passes in
108
runs 1 and 2 but fails in run 3, that result will not be displayed.
109
 
110
=item *
111
 
112
C<-x X:Y>: Differences which are identical to a difference between the two runs
113
given will B be displayed. For instance, if C<-x 1:2> is given and
114
test A passes in run 1 and fails in runs 2 and 3, that result will not be
115
displayed (since C<-x> will cause the difference between 1 and 2 to be ignored,
116
and the difference in 1 and 3 parallels the difference between 1 and 2.)
117
This option may only be used in conjunction with C<-i>.
