Some other optimizations might still rearrange code, so consider
-fno-strength-reduce and -fno-move-all-moveables and possibly a few other
switches. Just compile with -S and see if the assembly code looks right.

I think there is also a switch to force inline functions to be
instantiated, could be -fno-inline or -fforce-no-inline, but the former
solution is likely a lot better.
