abstract class InitialProducer extends AbstractInsnNode
A class for pseudo-instructions representing the initial producers of local values that have no producer instruction in the method:
- parameters, including
this
- uninitialized local variables
- exception values in handlers
The ASM built-in SourceValue analysis yields an empty producers set for such values. This leads to ambiguities. Example (in Java one can re-assign parameter):
int foo(int a) { if (a == 0) a = 1; return a; }
In the first frame of the method, the SourceValue for parameter a
gives an empty set of
producer instructions.
In the frame of the IRETURN
instruction, the SourceValue for parameter a
lists a single
producer instruction: the ISTORE 1
. This makes it look as if there was a single producer for
a
, where in fact it might still hold the parameter's initial value.
