I found cl::alias cannot be used to alias one option of another flag (e.g. -profile-correlate=debug-info). So, every place we uses ProfileCorrelate needs to have a check for DebugInfoCorrelate. I don't know how you update llvm toolchain, is it possible to switch to new flag at the time when updating the toolchain?
