Bill Currie	23613ca985	[simd] Get the new functions working on older hardware ... In some cases, gcc-11 does a good enough job translating normal looking C expressions so use just those, but other times need to dig around for an appropriate intrinsic. Also, now need to disable psapi warnings when compiling for anything less than avx.	2022-01-07 11:48:28 +09:00
Bill Currie	63db48bf42	[simd] Add integral loadvec3 versions that set w to 1 ... Always setting w to 0 made it impossible to use the resulting 4d vectors in division-based operations as they would result in divide-by-zero and thus an unavoidable exception (CPUs don't like integer div-by-zero). I'll probably add similar for float and double, but they're not as critical as they'll just give inf or nan. This also increases my doubts about the value of keeping 3d vector operations.	2022-01-04 18:23:32 +09:00
Bill Currie	0e1964bf74	[simd] Split out the ivec implementations ... And add any/all/none functions.	2022-01-02 16:02:57 +09:00
