-Routine Description:
-
- This is the POSTFIX version of the dependency evaluator. When a
- PUSH [PPI GUID] is encountered, a pointer to the GUID is stored on
- the evaluation stack. When that entry is poped from the evaluation
- stack, the PPI is checked if it is installed. This method allows
- some time savings as not all PPIs must be checked for certain
- operation types (AND, OR).
-
-Arguments:
-
- PeiServices - Calling context.
-
- DependencyExpression - Pointer to a dependency expression. The Grammar adheres to
- the BNF described above and is stored in postfix notation.
- Runnable - is True if the driver can be scheduled and False if the driver
- cannot be scheduled. This is the value that the schedulers
- should use for deciding the state of the driver.
-
-Returns:
-
- Status = EFI_SUCCESS if it is a well-formed Grammar
- EFI_INVALID_PARAMETER if the dependency expression overflows
- the evaluation stack
- EFI_INVALID_PARAMETER if the dependency expression underflows
- the evaluation stack
- EFI_INVALID_PARAMETER if the dependency expression is not a
- well-formed Grammar.

-/*++
-
-Routine Description:
-
- This is the POSTFIX version of the dependency evaluator. When a
- PUSH [PPI GUID] is encountered, a pointer to the GUID is stored on
- the evaluation stack. When that entry is poped from the evaluation
- stack, the PPI is checked if it is installed. This method allows
- some time savings as not all PPIs must be checked for certain
- operation types (AND, OR).
-
-Arguments:
-
- PeiServices - Calling context.
-
- DependencyExpression - Pointer to a dependency expression. The Grammar adheres to
- the BNF described above and is stored in postfix notation.
- Runnable - is True if the driver can be scheduled and False if the driver
- cannot be scheduled. This is the value that the schedulers
- should use for deciding the state of the driver.
-
-Returns:
-
- Status = EFI_SUCCESS if it is a well-formed Grammar
- EFI_INVALID_PARAMETER if the dependency expression overflows
- the evaluation stack
- EFI_INVALID_PARAMETER if the dependency expression underflows
- the evaluation stack
- EFI_INVALID_PARAMETER if the dependency expression is not a
- well-formed Grammar.
