// SIMPLIFIED TYPE SYSTEM
|
||
|
|
// ======================
|
||
|
|
// - All ints will be unsigned with exception of when signed is required.
|
||
|
|
// - Type naming simplified and shortened "A<type><#components>",
|
||
|
|
// - H = 16-bit float (half)
|
||
|
|
// - F = 32-bit float (float)
|
||
|
|
// - D = 64-bit float (double)
|
||
|
|
// - P = 1-bit integer (predicate, not using bool because 'B' is used for byte)
|
||
|
|
// - B = 8-bit integer (byte)
|
||
|
|
// - W = 16-bit integer (word)
|
||
|
|
// - U = 32-bit integer (unsigned)
|
||
|
|
// - L = 64-bit integer (long)
|
||
|
|
// - Using "AS<type><#components>" for signed when required.
|
||
|
|
//------------------------------------------------------------------------------------------------------------------------------
|
||
|
|
// TODO
|
||
|
|
// ====
|
||
|
|
// - Make sure 'ALerp*(a,b,m)' does 'b*m+(-a*m+a)' (2 ops).
|
||
|
|
// - Add subgroup ops.
|
||
|
|
//------------------------------------------------------------------------------------------------------------------------------
|
||
|
|
// CHANGE LOG
|
||
|
|
// ==========
|
||
|
|
// 20190531 - Fixed changed to llabs() because long is int on Windows.
|
||
|
|
// 20190530 - Updated for new CPU/GPU portability.
|
||
|
|
// 20190528 - Fix AU1_AH2_x() on HLSL (had incorrectly swapped x and y), fixed asuint() cases.
|
||
|
|
// 20190527 - Added min3/max3 for low precision for HLSL.
|
||
|
|
// 20190526 - Updated with half approximations, added ARsq*(), and ASat*() for CPU.
|
||
|
|
// 20190519 - Added more approximations.
|
||
|
|
// 20190514 - Added long conversions.
|
||
|
|
// 20190513 - Added the real BFI moved the other one to ABfiM().
|
||
|
|
// 20190507 - Added extra remap useful for 2D reductions.
|
||
|
|
// 20190507 - Started adding wave ops, add parabolic sin/cos.
|
||
|
|
// 20190505 - Added ASigned*() and friends, setup more auto-typecast, GLSL extensions, etc.
|
||
|
|
// 20190504 - Added min3/max3 for 32-bit integers.
|
||
|
|
// 20190503 - Added type reinterpretation for half.
|
||
|
|
// 20190416 - Added min3/max3 for half.
|
||
|
|
// 20190405 - Misc bug fixing.
|
||
|
|
// 20190404 - Cleaned up color conversion code. Switched "splat" to shorter naming "type_". Misc bug fixing.

// Same fast technique as documented here: ftp://ftp.fox-toolkit.org/pub/fasthalffloatconversion.pdf

// Supports denormals.
