Detailed Description
Set how locked data-types on the stack affect alias heuristics.
Stack analysis uses the following simple heuristic: a pointer is unlikely to reference (alias) a stack location if there is a locked data-type between the pointer base and the location. This option determines what kind of locked data-types block aliases in this way.
- none - no data-types will block an alias
- struct - only structure data-types will block an alias
- array - array data-types (and structure data-types) will block an alias
- all - all locked data-types will block an alias

Apply a particular configuration option to the Architecture.
This method is overloaded by the different Option classes to provide possible configuration of different parts of the Architecture. The user can provide up to three optional parameters to tailor a specific type of configuration. The method returns a confirmation/failure message as feedback.
- Parameters
-
glb is the Architecture being configured p1 is the first optional configuration string p2 is the second optional configuration string p3 is the third optional configuration string
- Returns
- a confirmation/failure message
Implements ArchOption.
