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>. + +=back + +=cut + +use strict; +use warnings; +use Getopt::Long; + +use FindBin qw($Bin); +use lib "$Bin"; +use dglib; + +my %options; +my $error = undef; + +if(!GetOptions( + "p" => \$options{p}, + "i=s" => \$options{i}, + "x=s" => \$options{x}, +)) { + $error = ""; +} elsif(@ARGV != 2 and @ARGV != 3) { + $error = ""; +} elsif($options{x} and !$options{i}) { + $error = "-x may only be given in conjunction with -i."; +} else { + foreach my $opt("i", "x") { + if($options{$opt} and + ($options{$opt} !~ /^([123]):([123])$/ or + $1 == $2) + ) { + $error = "Invalid -$opt argument."; + } + } +} + +if(defined($error)) { + print STDERR "$error\n" if $error; + print STDERR "Usage: compareSumTests3 [-p] [-i X:Y [-x X:Y]] old1.sum old2.sum new.sum\n"; + print STDERR "Try 'perldoc $0' for further information.\n"; + exit 1; +} + +my(@sumfiles) = @ARGV; +-f $_ || die "$_ is not a regular file!\n" foreach @sumfiles; +my(%results, @inc_changes, @exc_changes, %checksums); + +# We decrement the values given so that they correspond +# to indices into our results array. +if($options{i}) { + $options{i} =~ /(\d+):(\d+)/; + @inc_changes = ($1 - 1, $2 - 1); +} +if($options{x}) { + $options{x} =~ /(\d+):(\d+)/; + @exc_changes = ($1 - 1, $2 - 1); +} + + +my %analyzed_results = compareSumFiles(\@sumfiles); + +foreach my $cat (qw(improvements regressions miscellaneous)) { + if(@sumfiles == 3) { + my @subcounts; + if(!$options{p}) { + $subcounts[$_] = @{$analyzed_results{$cat}->[$_] || []} for(0..2); + print "\u$cat: ", ($subcounts[0]+$subcounts[1]+$subcounts[2]), "\n"; + } + + for(my $i = 0; $i < 3; $i++) { + if(!$options{p} and $cat ne "miscellaneous") { + if($i == 0) { + if($cat eq "regressions") { + print "\tSuccess in old1 only: $subcounts[$i]\n"; + } else { + print "\tFailure in old1 only: $subcounts[$i]\n"; + } + } elsif($i == 1) { + if($cat eq "regressions") { + print "\tSuccess in old2 only: $subcounts[$i]\n"; + } else { + print "\tFailure in old2 only: $subcounts[$i]\n"; + } + } else { + if($cat eq "regressions") { + print "\tFailure in new only: $subcounts[$i]\n"; + } else { + print "\tSuccess in new only: $subcounts[$i]\n"; + } + } + } + + foreach my $test (sort {$a->{name} cmp $b->{name}} @{$analyzed_results{$cat}->[$i] || []}) { + if(!$options{p}) { + if($cat eq "miscellaneous") { + print "\t"; + } else { + print "\t\t"; + } + } else { + if($cat eq "regressions") { + print "R"; + } else { + print "I"; + } + + print $i+1, " "; + } + printf "%s [%s,%s,%s]\n", $test->{name}, $test->{data}->[0], $test->{data}->[1], $test->{data}->[2]; + } + } + } else { + if(!$options{p}) { + my $subcount = @{$analyzed_results{$cat}}; + print "\u$cat: $subcount\n"; + } + + foreach my $test (sort {$a->{name} cmp $b->{name}} @{$analyzed_results{$cat}}) { + if(!$options{p}) { + print "\t"; + } else { + if($cat eq "regressions") { + print "R"; } else { + print "I"; + } + + print " "; + } + printf "%s [%s,%s]\n", $test->{name}, $test->{data}->[0], $test->{data}->[1], $test->{data}->[2]; + } + } +} diff --git a/gcc-4.3.1/contrib/compare_tests b/gcc-4.3.1/contrib/compare_tests new file mode 100755 index 000000000..bed97429d --- /dev/null +++ b/gcc-4.3.1/contrib/compare_tests @@ -0,0 +1,111 @@ +#!/bin/sh +# This script automatically test the given tool with the tool's test cases, +# reporting anything of interest. + +# exits with 0 if there is nothing of interest +# exits with 1 if there is something interesting +# exits with 2 if an error occurred + +# Give two .sum files to compare them + +# Written by Mike Stump <mrs@cygnus.com> + +tool=gxx + +tmp1=/tmp/$tool-testing.$$a +tmp2=/tmp/$tool-testing.$$b +now_s=/tmp/$tool-testing.$$d +before_s=/tmp/$tool-testing.$$e + +if [ "$2" = "" ]; then + echo "Usage: $0 previous current" >&2 + exit 2 +fi + +sed 's/^XFAIL/FAIL/; s/^XPASS/PASS/' < "$1" | awk '/^Running target / {target = $3} { if (target != "unix") { sub(/: /, "&"target": " ); }; print $0; }' >$tmp1 +sed 's/^XFAIL/FAIL/; s/^XPASS/PASS/' < "$2" | awk '/^Running target / {target = $3} { if (target != "unix") { sub(/: /, "&"target": " ); }; print $0; }' >$tmp2 + +before=$tmp1 +now=$tmp2 + +exit_status=0 +trap "rm -f $tmp1 $tmp2 $now_s $before_s" 0 1 2 3 5 9 13 15 + +if sort -k 2 </dev/null >/dev/null 2>&1; then + skip1='-k 2' +else + skip1='+1' +fi + +sort -t ':' $skip1 "$now" > "$now_s" +sort -t ':' $skip1 "$before" > "$before_s" + +grep '^FAIL:' "$now_s" | sed 's/^[^:]*:[ ]//' >$tmp1 +grep '^PASS' "$before_s" | sed 's/^[^:]*:[ ]//' | comm -12 $tmp1 - >$tmp2 + +grep -s . $tmp2 >/dev/null +if [ $?

The Pascal +version below cannot therefore be exactly the same. Rather than be +a minimal transcription of the BASIC program, the Pascal coding +follows the conventional style of block-structured languages. Hence +the Pascal version could be useful in producing versions in other +structured languages. + +Rather than use identifiers of minimal length (which therefore have +little mnemonic significance), the Pascal version uses meaningful +identifiers as follows [Note: A few changes have been made for C]: + + +BASIC C BASIC C BASIC C + +A J S StickyBit +A1 AInverse J0 NoErrors T +B Radix [Failure] T0 Underflow +B1 BInverse J1 NoErrors T2 ThirtyTwo +B2 RadixD2 [SeriousDefect] T5 OneAndHalf +B9 BMinusU2 J2 NoErrors T7 TwentySeven +C [Defect] T8 TwoForty +C1 CInverse J3 NoErrors U OneUlp +D [Flaw] U0 UnderflowThreshold +D4 FourD K PageNo U1 +E0 L Milestone U2 +E1 M V +E2 Exp2 N V0 +E3 N1 V8 +E5 MinSqEr O Zero V9 +E6 SqEr O1 One W +E7 MaxSqEr O2 Two X +E8 O3 Three X1 +E9 O4 Four X8 +F1 MinusOne O5 Five X9 Random1 +F2 Half O8 Eight Y +F3 Third O9 Nine Y1 +F6 P Precision Y2 +F9 Q Y9 Random2 +G1 GMult Q8 Z +G2 GDiv Q9 Z0 PseudoZero +G3 GAddSub R Z1 +H R1 RMult Z2 +H1 HInverse R2 RDiv Z9 +I R3 RAddSub +IO NoTrials R4 RSqrt +I3 IEEE R9 Random9 + +SqRWrng + +All the variables in BASIC are true variables and in consequence, +the program is more difficult to follow since the "constants" must +be determined (the glossary is very helpful).
