Hi, I would like to propose a new !annotation metadata kind that can be attached to arbitrary instructions to drive generating remarks that provide additional insight into transformations applied to a program. To motivate this, consider these specific questions we would like to get answered: * How many stores added for automatic variable initialization remain after optimizations? Where are

Cool! I really like the idea. I left a comment about metadata preservation below. Once this is available we will certainly employ it to understand OpenMP programs better. We could also think about a user facing version of this while we are at it ;) ~ Johannes On 11/4/20 3:57 PM, Florian Hahn via llvm-dev wrote: > Hi, > > > I would like to propose a new !annotation metadata kind
