184Routine Description:\r
185\r
186 This is the POSTFIX version of the dependency evaluator. When a\r
187 PUSH [PPI GUID] is encountered, a pointer to the GUID is stored on\r
188 the evaluation stack. When that entry is poped from the evaluation\r
189 stack, the PPI is checked if it is installed. This method allows\r
190 some time savings as not all PPIs must be checked for certain\r
191 operation types (AND, OR).\r
192\r
193Arguments:\r
194\r
195 PeiServices - Calling context.\r
196\r
197 DependencyExpression - Pointer to a dependency expression. The Grammar adheres to\r
198 the BNF described above and is stored in postfix notation.\r
199 Runnable - is True if the driver can be scheduled and False if the driver\r
200 cannot be scheduled. This is the value that the schedulers\r
201 should use for deciding the state of the driver.\r

205 Status = EFI_SUCCESS if it is a well-formed Grammar\r
