Like -fhardened?
Sure.
-f is technically machine independent.
-m should be used when having it implemented as machine dependent options.
So if you are telling me all these security features are only developed without requiring to implement per machine level support then it makes sense.
The interactions between different optimization passes may have surprising consequences.
Endless loops are technically undefined behavior, can be dropped, except for their assembly jump tag entry point, and collide with the next function's assembly jump tag.
All because of UB.
Huge headache. Try debugging that.
And interaction loops on games are sometimes endlessly waiting for input.
