+# This testcase will fail with a warning "xt defined on removed toc entry"
+# if a large-toc access like the following is added to this file, because
+# toc analysis only considers toc accesses from the current object file.
+# The small-toc access from tocopt4a.s doesn't cause xt entry to be marked
+# !can_optimize. The testcase only passes because toc analysis considers
+# *no* access from the current file as being sufficiently unusual to
