But that's no reason at all, you have no control of what the transistors are doing below. Any semi-high level language you use is optimized on the compiler level so that no matter what you write, it will work as efficiently as possible. This isn't the old days where cool little tricks actually worked in C.
Since when has "semi-high level language" been used to describe what you do? Embedded systems and DSP code are no where near high-level.
