Apologies, I omitted the -O1 / -O2 

$ docker run --privileged --rm -it -v /tmp:/tmp gcc:10.2 bash -c "gcc -c
/tmp/test4.c -S -o - -O2 -fno-omit-frame-pointer -mno-omit-leaf-frame-pointer 
| grep rbp"

$ docker run --privileged --rm -it -v /tmp:/tmp gcc:7.5 bash -c "gcc -c
/tmp/test4.c -S -o - -O2 -fno-omit-frame-pointer -mno-omit-leaf-frame-pointer 
| grep rbp"
        pushq   %rbp
        movq    %rsp, %rbp
        popq    %rbp
        popq    %rbp
