MaxMath v2.1.2

Known Issues

• half8 "equals" and "not equals" operators don't conform to the IEEE 754 standard - Unity has not yet reacted to my bug-report in regards to their "half" implementation

Fixes

• fixed undefined behavior of "vshr" functions for vector types smaller than 128 bits
• fixed SSE2 implementations of "vrol" and "vror" functions for the (u)short16 type

Additions

• implemented Bmi1 and Bmi2 intrinsics as functions with a "bits_" prefix (except for "andn", which has already been implemented as "andnot")
• added high performance and/or SIMD "isdivisible" functions for all integer vector types and scalar value types
• added high performance and/or SIMD "intpow" - integer exponentiation - functions for (u)int, (u)long and all integer vector types
• added high performance and/or SIMD "floorpow2" functions for all integer vector types
• added "nabs" - negative absolute value functions for all non-boolean vector- and single value types
• added "indexof(vector v, value x)" functions for all non-boolean vector types

Improvements

• aggressivley optimized away global variables (shuffle masks) and thus memory access and usage where appropriate
• improved performance of 256 bit vector subvector getters
• added Sse2 fallback code for all (u)long2/3/4 operators
• improved performance of mulitplication, division and modulo operations for all (s)byte- and (u)short vector- and matrix types when dividing by a single non-compile time constant value
• added overloads for (s)byte- and (u)short vectors' "divrem" functions with a scalar value as the divisor parameter, improving performance when it is a compile time constant
• improved performance of "intsqrt" functions for most types

Changes

• bump com.unity.burst to version 1.5

Fixed Oversights

• added bitmask8 and bitmask16 functions for (s)byte and (u)short vector types, respectively
