+# Check dissassembly of the .plt section, specifically the synthetic
+# symbols, in a DSO in which a .got.plt entry has been merged into a
+# regular .got entry. There was a bug in which some (i.e. subsequent
+# with regards to reloc order) synthetic X@plt entries were wrong if
+# there were merged .got entries present; dsofn4@plt below. The
+# alternatives in the matching regexps are placeholders for a future
+# improvement: synthetic symbols for .plt entries with merged .got
+# entries (lost as a consequence of the relocs no longer accounted for
+# in .rela.plt and the default synthetic-symbol implementation just
+# iterating over .rela.plt).
