The current code follows the nonsensical asm generated by agbcc, which converted a subtraction by 16 into an addition by a halfword value of -16. This conversion happened at the portion of the compiler that does platform-specific transformations. This code in C is UB, as it relies on overflowing of a negative value. Signed-off-by:Arven
