Hi Andre and welcome!
I'm relatively new to LLVM so I understand and I may be able to help. First
of all, by reading your message, it seems that you want
to work on code that runs fast (i.e. high-performance data structures used
in LLVM) and not necessarily code that produces fast code (e.g. LLVM
Ask if that distinction was not clear.
For that, I guess that a good place to start is the Abstract Data Types:
IIRC, most DS's that Chandler mentions are there. Now, how do you start
there is a different story. At least, you don't need to know
much about compilers. One thing I'd suggest is to do a search in the whole
directory for FIXME or TODO. Then, try to find
some that (at least) seem easy and try to fix them. Then, submit a patch in
the Phabricator: https://llvm.org/docs/Phabricator.html
Even if you get it wrong, people are very kind on the reviews.
Lastly, regarding this:
> I would like to work on a project that, in addition to my interests
above, also allows me to use the latest C++ features.
Definitely I don't have a complete picture of LLVM to talk extensively
about the topic but here's the thing with C++. Applying
a lot of C++ intricacies does not help in the end and the reason is that
the code becomes too complex and you
require the developer / reader to know all these intricacies. So, you'll
definitely find such in LLVM
but only when those are actually helpful. I'd suggest that if you want to
take C++ on its limits, you can
try it on a personal project (that's a personal opinion).
Please ask if anything was unclear.
