Apparently according to some ACCU and CPPCon talks by Khalil Estel this can be largely mitigated even in embedded lowering the size cost by orders of magnitude.
Yeah. I unfortunately moved to an APU where code size isn't an issue so I never got the chance to see how well that analysis translated to the work I do.
Provocative talk though, it upends one of the pillars of deeply embedded programming, at least from a size perspective.
