The PIC18 compiler (read, POS) does not optimize out the divide-by-8 in the bitfieldspecial.c routine.
Replacing /8 with >>3 results in a performance boost for the PIC compiler of 60%.
/8
>>3
@billvaglienti can you see any issues with this in general? Slightly reduces code readability but enforces good behavior by the compiler.
