This name should be hard-coded in the assembly string. Clang doesn't seem to support `%p` modifier with an `i` input: https://gcc.godbolt.org/z/7shcoGMWq
When you want to use a modifier in inline assembly, please do also test Clang. It's a much more risky area where occasionally wrong results can happen.
