+# The purpose of this test is to check the interaction between the code
+# to ensure exact PCC bounds and the code that inserts stubs. We want to
+# make sure we still get tight PCC bounds even when stubs are requried.
+#
+# For the PCC bounds, we now add padding *after* the end of the last
+# section in PCC bounds (instead of padding the last section itself).
+# Hence we check that the PCC span ends where the .tail_relro section
+# starts, rather than checking where .text_high ends.
