After the last post, you might think that I have spent most of my time lately with IL2CPP. That, however, is untrue: I have actually mostly been looking at GPU hangs. I would by no means call myself a graphics programmer: When I program for GPUs, it’s either a compute... [Read More] -

bool4 and an unexpected new perspective
This blog post is 20 paragraphs exposition and 2 paragraphs punchline. It is a follow-up to my previous post on vectorization. I mentioned there that Unity’s math package implements bool4 like this: struct bool4 { [MarshalAs(U1)] public bool x; [MarshalAs(U1)] public bool y; [MarshalAs(U1)] public bool z; [MarshalAs(U1)] public bool...

Nobody cares about vectorization?
In a recent discussion around auto-vectorization someone suggested: “What if users could tell the compiler that they expect a loop to be vectorized?” We are in luck, that experiment has already been conducted. In particular, Unity’s Burst compiler has an intrinsic for that (see Burst docs). Put Loop.ExpectVectorized(); into a... [Read More]
