change log for vectorclass.zip
------------------------------
2015-10-24 version 1.16
* workaround for problem in Clang compiler extended to version 3.09 because not fixed yet by Clang
(vectorf128.h line 134)
* recognize problem with Apple version of Clang reporting wrong version number
* remove various minor problems with Clang
* function pow(vector, int) modified to strengthen type checking and avoid compiler warnings
* manual discusses dynamic allocation of arrays of vectors
* various minor changes
2015-10-17 version 1.15
* added files ranvec1.h and ranvec1.cpp for random number generator
* constructors to make boolean vectors from their elements
* constructors and = operators to broadcast boolean scalar into boolean vectors
* various lookup functions improved
* operators &, |, ^, ~, etc. defined for various boolean vectors to avoid converson
to integer vectors
* nmul_add functions
* mul_add etc. moved to main header files
* explicit fused multiply-and-add used in math functions to improve performance
on compilers that don't automatically insert FMA
2014-07-24 version 1.14
* support for AVX-512f instruction set and 512-bit vectors:
Vec16i, Vec16ui, Vec8q, Vec8uq, Vec16f, Vec8d, and corresponding boolean vectors
* new define MAX_VECTOR_SIZE, valid values are 128, 256 and 512
* added hyperbolic functions sinh, cosh, tanh, asinh, acosh, atanh
* size() member function on all vector classes returns the number of elements
* functions for conversion between boolean vectors and integer bitfields
* extracting an element from a boolean vector now returns a bool, not an int
* improved precision in exp2 and exp10 functions
* various bug fixes
2014-05-11 version 1.13
* pow function improved
* mul_add, mul_sub, mul_sub_x functions
* propagation of error codes through nan_code function
* "denormal" renamed to "subnormal" everywhere, in accordance with IEEE 754-2008 standard
2014-04-20 version 1.12
* inline implementation of mathematical functions added (vectormath_exp.h vectormath_trig.h vectormath_common.h)
* vectormath.h renamed to vectormath_lib.h because a new alternative is added
* gather functions with constant indexes
* function sign_combine
* function pow_const(vector, const int)
* function pow_ratio(vector, const int, const int)
* functions horizontal_find_first, horizontal_count

* function Vec4i round_to_int(Vec2d)
* operator & (float vector, boolean vector)
* operator &= (int vector, int vector)
* removed constructor Vec128b(int) and Vec256b(int) to avoid implicit conversion
* removed signalling nan function
* minor improvements in various blend and lookup functions
2014-03-01 version 1.11
* fixed missing unsigned operators >>= in vectori256.h
2013-10-04 version 1.10
* clear distinction between boolean vectors and integer vectors for the sake of
compatibility with mask registers in forthcoming AVX512 instruction set
* added function if_add
* tentative support for clang version 3.3 with workaround for bugs
* remove ambiguity for builtin m128i operator == in clang compiler.
* problems in clang compiler, bug reports filed at clang
(http://llvm.org/bugs/show_bug.cgi?id=17164, 17312)
* instrset.h fixes problem with macros named min and max in MS windows.h
