* Reorder some math terms to help optimizationsChris Robinson2018-12-151-6/+6
| | | | | | | | | | | | | | | | | | | | | | | Because floating-point math is not associative ((a*b)*c does not necessarily give the same result as a*(b*c)), the ordering of terms can inhibit reuse of temporary values. For example, both coeffs[9] = 2.091650066f * y * (3.0f*x*x - y*y); and coeffs[15] = 2.091650066f * x * (x*x - 3.0f*y*y); contain x*x and y*y terms that could be calculated once, stored in temporary registers, and reused to multiply with 3. But since 3.0f*(x*x) would produce different results, the compiler is not allowed to make that optimization. If, however, the multiply with 3 is moved to the right side: coeffs[9] = 2.091650066f * y * (x*x*3.0f - y*y); and coeffs[15] = 2.091650066f * x * (x*x - y*y*3.0f); in both cases x*x and y*y are calculated first in their respective groups, guaranteeing the same results for both instances prior to the multiply with 3 and allowing the compiler to reuse those intermediate values.
