+// The following is a minimal set of alias for the opcode names. This is needed
+// because there is code (e.g. in GetByIdStatus.cpp and PutByIdStatus.cpp)
+// which refers to the opcodes expecting them to be prefixed with "llint_".
+// In the CLoop implementation, the 2 are equivalent. Hence, we set up this
+// alias here.
+//
+// Note: we don't just do this for all opcodes because we only need a few,
+// and currently, FOR_EACH_OPCODE_ID() includes the llint and JIT opcode
+// extensions which we definitely don't want to add an alias for. With some
+// minor refactoring, we can use FOR_EACH_OPCODE_ID() to automatically
+// generate a llint_ alias for all opcodes, but that is not needed at this
+// time.
