This isn't sufficient information to help you fix your problem.
Is @const_expr a function, and LLVM constant expression, or
something else? If it's a function, did you verify that it has a
body (i.e., it's not a function declaration)?<br>

<div>For example, as shown in the following dump result, how can
i selectively omit function "@const_expr" in the input module?
Is there a general way to run some function only but omit
others? Thanks!</div>
