Constants
public static final int FLAG_OPND_HAVE_SAME_BITSIZE
This flag indicates that all operands should have the same bitsize. This check is enforced when creating operations using such a function type.
Constant Value:
1
(0x00000001)
public static final int FLAG_PASSTHRU_FOR_ECALL_DFA_CALCULATION
This flag is reserved for single-operand custom operators to specify that the operand is to be treated as a pointer, and the data pointed by it should be treated as such during data-flow calculations.
This is especially important for DFA calculations of IECall. Essentially, code like:
call(1, 2, 3, CUSTOM_FUNC(par_stkvarX))will be treated the same as the following by
IECall.getDefUse():
call(1, 2, 3, par_stkvarX)
Constant Value:
16
