216\r
217Routine Description:\r
218\r
219 This is the POSTFIX version of the dependency evaluator. When a\r
220 PUSH [PPI GUID] is encountered, a pointer to the GUID is stored on\r
221 the evaluation stack. When that entry is poped from the evaluation\r
222 stack, the PPI is checked if it is installed. This method allows\r
223 some time savings as not all PPIs must be checked for certain\r
224 operation types (AND, OR).\r
225\r
226Arguments:\r
227\r
228 PeiServices - Calling context.\r
229\r
230 DependencyExpression - Pointer to a dependency expression. The Grammar adheres to\r
231 the BNF described above and is stored in postfix notation.\r
232 Runnable - is True if the driver can be scheduled and False if the driver\r
233 cannot be scheduled. This is the value that the schedulers\r
234 should use for deciding the state of the driver.\r
235\r
236Returns:\r
237\r
238 Status = EFI_SUCCESS if it is a well-formed Grammar\r
239 EFI_INVALID_PARAMETER if the dependency expression overflows\r
