(byte-optimize-plus): Don't call byte-optimize-delay-constants-math (bug#1334). Use byte-optimize-predicate to optimize constants. (byte-optimize-minus): Don't call byte-optimize-delay-constants-math. Remove zero arguments first if possible. Call byte-optimize-predicate to optimize constants. (byte-optimize-multiply): Remove optimizations for arguments of 0 and 2, which may be inaccurate. Optimize (* x -1) to (- x). Call byte-optimize-predicate. (byte-optimize-divide): Leave runtime errors unchanged. Optimize (/ x 1) to (+ x 0). Remove optimizations for arguments of 0 and 2.0, which may be inaccurate. Call byte-optimize-predicate.
