Determine if the call can access memory only using pointers based on its arguments.

Determine if the function may only access memory that is either inaccessible from the IR or pointed to by its arguments.

Determine if the function may only access memory that is inaccessible from the IR.

Determine if the call does not access or only reads memory.

Implementation of a = b | c => a = (b & c) | (b ^ c)

Implementation of a = a | b => a = (((~a & r) | (a & ~r)) ^ ((~b & r) | (b & ~r))) | (~(~a | ~b) & (r | ~r))
