And for 2.95.3 there was thorough testing of both 2.95.2 and the branch
against a current testsuite version, to detect regressions shown up by the
testsuite <http://gcc.gnu.org/gcc-2.95/testing.html>. Similar testing was
done for previous releases as well. So instructions on how to test
previous compiler versions (whether installed or building them for the
purpose) with the current testsuite would be useful (with test results for
the past versions and the branch then sent to gcc-testresults); comparison
of the results on the primary and secondary platforms can then show what
regressions there are in the testsuite. (Revision 1.102 of
gcc-2.95/regress.html has some instructions that were used in the past on
testing with past installed versions.)
Of course having the testcase library of testcases for PRs
<http://gcc.gnu.org/ml/gcc/2002-12/msg01250.html> in the testsuite would
make such testing more useful.
