Optimization at the speed of 1.6 Kilo-Fredriksson
I have already introduced my latest project cpp2better in a previous post. I have made good progress and wanted to share some results.

GPU hang adventures
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] -
IL2CPP, but better
IL2CPP is Unity’s AOT solution for C#, which takes compiled C# in the form of IL-code and turns it into C++ code, which can then be compiled using regular native toolchains. I have looked at a lot of this generated C++ code and the machine code it compiles to. There... [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]
