   it's well known that compilers rare produce wanted code.   
   many programmers add inline ASM or modify the gotten.

   this reminds me when I started programming PCs decades   
   ago with ROM BASIC and a bit later with Power-Basic.   
   I always had to scratch my back around seven corners to   
   achieve what I wanted.   
   After enough annoyed by all these delaying detours   
   which ended up in bloatware I started with inline ASM.   
   But this wasn't satisfying either because tools were   
   not aware of all possible code opportunity, so I had   
   to enter inline code byte by byte (aka DB 0x..).   
      
   this finally made my write my own tools and a whole OS.   
   while doing my tools I learned to code in HEX for almost   
   all CPUs popular back then [Zilog,Motorola,RCA,NSC,Intel]
