+# variations of the same tests more than once, shall prefix the
+# different test invocations with different identifying strings in
+# order to make them unique.
+#
+# About test prefixes:
+#
+# $pf_prefix is the string that dejagnu prints after the result (FAIL,
+# PASS, etc.), and before the test message/name in gdb.sum. E.g., the
+# underlined substring in
+#
+# PASS: gdb.base/mytest.exp: some test
+# ^^^^^^^^^^^^^^^^^^^^
+#
+# is $pf_prefix.
+#
+# The easiest way to adjust the test prefix is to append a test
+# variation prefix to the $pf_prefix, using the with_test_prefix
+# procedure. E.g.,
+#
+# proc do_tests {} {
+# gdb_test ... ... "test foo"
+# gdb_test ... ... "test bar"
+#
+# with_test_prefix "subvariation a" {
+# gdb_test ... ... "test x"
+# }
+#
+# with_test_prefix "subvariation b" {
+# gdb_test ... ... "test x"
+# }
+# }
+#
+# with_test_prefix "variation1" {
+# ...do setup for variation 1...
+# do_tests
+# }
+#
+# with_test_prefix "variation2" {
+# ...do setup for variation 2...
+# do_tests
+# }
+#
+# Results in:
+#
+# PASS: gdb.base/mytest.exp: variation1: test foo
+# PASS: gdb.base/mytest.exp: variation1: test bar
+# PASS: gdb.base/mytest.exp: variation1: subvariation a: test x
+# PASS: gdb.base/mytest.exp: variation1: subvariation b: test x
+# PASS: gdb.base/mytest.exp: variation2: test foo
+# PASS: gdb.base/mytest.exp: variation2: test bar
+# PASS: gdb.base/mytest.exp: variation2: subvariation a: test x
+# PASS: gdb.base/mytest.exp: variation2: subvariation b: test x
+#
+# If for some reason more flexibility is necessary, one can also
+# manipulate the pf_prefix global directly, treating it as a string.
+# E.g.,
+#
+# global pf_prefix
+# set saved_pf_prefix

+# ... actual tests ...
+# set pf_prefix $saved_pf_prefix
