+# This test tries to check that the SMT-LIBv2 we generate when a AShrExpr is
+# used is correct.
+#
+# FIXME: We should really pass the generated query to an SMT solver that supports
+# SMT-LIBv2 and check it gives the correct answer ``unsat``. An older version of
+# KLEE where AShrExpr wasn't handled correctly would give ``sat`` for this query.
+#
+# We could fix this if we required STP to be in the user's PATH and made available
+# as a substitution in llvm-lit
