218Routine Description:\r
219\r
220 This is the POSTFIX version of the dependency evaluator. When a\r
221 PUSH [PPI GUID] is encountered, a pointer to the GUID is stored on\r
222 the evaluation stack. When that entry is poped from the evaluation\r
223 stack, the PPI is checked if it is installed. This method allows\r
224 some time savings as not all PPIs must be checked for certain\r
225 operation types (AND, OR).\r
226\r
227Arguments:\r
228\r
229 PeiServices - Calling context.\r

231 DependencyExpression - Pointer to a dependency expression. The Grammar adheres to\r
232 the BNF described above and is stored in postfix notation.\r
