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

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