[llvm-dev] Attempting EuroLLVM2020 as a beginner
I received this request off-list:> I would really love seeing presentations or workshops about the JIT. Kinda like the KaldeiscopeJIT tutorials but in a guided way to ask questions and improve understanding about it. Especially for use under windows since this seems to be rather rare.-Hal On 11/26/19 10:49 AM, Hal Finkel wrote: If you have suggestions for content, sending that here is probably best.

[llvm-dev] Attempting EuroLLVM2020 as a beginner
Hey Lang, Thank you for those links! I will look into them the next days – hopefully. I think I’m actually looking for recipe-style and a higher-level design. Not sure how to explain it, but I’m pretty new to the JIT subject. I started with the MCJIT (I guess?) and tons of help from you Lang (Thanks again for that). I was then able to do the following with the MCJIT: * Providing my own memory (not using what ever the LLVM is hiding from me) * Placing code into shared memory for example * Providing my own addresses for symbols (not using the correct addresses from the process it runs on) * Again for shared memory purposes * Changing the code model to small and using PIC relocations Then I noticed that Orc was coming and I started with Kaleidoscope tutorial – that was good for a short introduction, but didn’t helped me with any of the stuff I was able to do with MCJIT – now I learned, that even an Orc2 is coming? I start to become a bit lost! From the tutorial I personally hope to: 1. Learn how to do the stuff I was able to do with MCJIT 2. Learn more about the LLVM concepts itself (How can I ask for things I’m not aware of?) 3. Learn best practises For point 3. for example: I learned that I can resolve functions with plain functions in the LLVM::Module – is it better to resolve a function there or waiting for MCJIT to do it there? Stuff like that… All in all I would like to become more independent – hoping to understand the basics so I could learn/discover the more complex stuff myself. I really hope that made things more clear? It Is difficult for me to explain because the entire subject is really complex.
