I'm trying to understand what you mean. You mean that directly using "integer_zero_node" to overwrite decl will not guarantee whether the memory of the original decl has been properly cleaned up, right? If so, then the current method is really not appropriate. Maybe I should check whether the function has been registered before registering the current function. If it has been registered, I will skip it directly. This will lead to a decrease in efficiency. I am not sure whether this is appropriate. In fact, I see a similar patch on aarch64: https://github.com/gcc-mirror/gcc/commit/685d822e524cc8b2726ad6c44c2ccaabe55a198c Or any other comments? BR Jin
