We wrote an article about -fno-semantic-interposition flag that we use with GCC on RHEL8 and Fedora:
https://developers.redhat.com/blog/2020/06/25/red-hat-enterprise-linux-8-2-brings-faster-python-3-8-run-speeds/
"Enabling this flag disables semantic interposition, which can increase run speed by as much as 30%."

In short, the flag allows the compiler to inline code and so make further optimizations, when Python is built with --enable-shared.
