As for how Rainer settled on that solution, I'm hoping to get a guest post out of him (though I haven't asked him yet, so shhhh!). [1] https://dlang.org/spec/abi.html#back_ref

The new version is much better with only a 6 MB difference between the stripped and non-stripped versions.

The new version is much better with only a 6 MB difference between the stripped and non-stripped versions. My vibe-d application debug build reduced from 56Mb to 44Mb (release = 19Mb).

A blog post I wrote about the issue itself (and a workaround that I employed to achieve the same result) is here: http://www.schveiguy.com/blog/2016/05/have-your-voldemort-types-and-keep-your-disk-space-too/ I hope Rainer agrees to the blog post as well. While I understand the concept, a detailed description of how the back references work would be very interesting. -Steve

I have SIGSEGV when using DMD and simd types. This code works ok with GDC and LDC fine, but SIGSEGV with latest DMD (maybe even with previous versions I do not know)

I think that GDC and LDC do do auto-vectorization, but I haven't verified it myself. Auto-vectorization is a fundamentally bizarre feature. It takes low level code and reverse-engineers it back into a higher level construct, and then proceeds to generate code for that higher level construct. Everything else a compiler does is start from a high level construct and then generate low level code. The trouble with AV is whether it succeeds or not depends on peculiarities (and I mean peculiarities) of the particular vector instruction set target. It can decided to not vectorize based on seemingly trivial and innocuous changes to the loop. The only way to tell is to benchmark it or look at the object file - methods that are unreliable (benchmarking) or do not scale (manually looking at the object file). What's needed is a language feature that is straightforwardly vectorizable. That would be D's array operations.
