<stikonas>was chasing a bug in x86_64 assembly for some time... Turns out I should have paid more attention to calling convention, r11 is volatile
<stikonas>oh, I might need to redo hex0_AMD64 conversion to hex0 again, spotted another big optimization
<stikonas>in fact on x86 too, just not as much
<stikonas>all those char operations work on rax / eax which is 4 / 3 bytes. but we can just use al which is only 2 bytes
