Even more recordings from the 2021 LLVM Developers' Meeting are now available. A tutorial on ORCv2 from the meeting has also been published.

Arseny Kapoulkine blogged about Proebsting’s Law, putting it to test using LLVM and Clang (is it really the case that compiler advances double computing power every 18 years?). The overall conclusion was “LLVM 11 tends to take 2x longer to compile code with optimizations, and as a result produces code that runs 10-20% faster (with occasional outliers in either direction), compared to LLVM 2.7 which is more than 10 years old.”
