(* The domain for the analysis is sets of global variables if an initialization is needed at
|
||
|
|
runtime, or Bottom if no initialization is needed. For instance, `int x = 32; int y = x * 52;`
|
||
|
|
gives a summary of Bottom for both initializers corresponding to these globals, but `int x =
|
||
|
|
foo();` gives a summary of at least "NonBottom {}" for x's initializer since x will need runtime
|
||
|
|
initialization.
|
||
|
|
|
||
|
|
The encoding in terms of a BottomLifted domain is an efficiency hack to represent two pieces of
|
||
|
|
information: whether a global variable (via its initializer function) requires runtime
|
||
|
|
initialization, and which globals requiring initialization a given function (transitively)
|
||
|
|
accesses. *)
