llvm is getting slower, January edition
Hi,
Continuing recent efforts in understanding compile time slowdowns, I looked at some historical data: I picked one test and tried to pin-point commits that affected its compile-time. The data I have is not 100% accurate, but hopefully it helps to provide an overview of what's going on with compile time in LLVM and give a better understanding of what changes usually impact compile time.
