Reorganization and list of D libraries (300+)
Hi all. Lurking in this forum I had the feeling that lots of D developers tend to rewrite lots of code that could be found in libraries. This is not bad per se but I thought that one of the reason could have been the current process of library discovery. For this reason I have edited a list of libraries that could aid in this process. I also considered that the following features could be of importance to you: - License - Garbage collector - last modification (automated) The list is of course not complete and I could not test all of the libraries I included. I welcome you to modify it, open PRs or issues on github. https://github.com/FraMecca/D_Libraries_Registry I hope it could lead to a better ecosystem for the whole D community.

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. I’ll share an anecdotal experience from a time I worked in reasearch lab of a well known tech giant. 2 senior researchers spent literally 2 weeks trying to coerce compiler into vectorizing an inner loop of a non-trivial matrix algorithm. The only diagnostic from compiler was “loop form is not correct”. Thankfully it did tell them it failed, else they’d have to disassemble it each time. I think eventually they either rewritten it to fit heuristic or just carried on with explicit intrinsics. What's needed is a language feature that is straightforwardly vectorizable. That would be D's array operations. Sadly array ops would be insufficient for said problem. It wasn’t a direct element wise expression.
