Hi, this is a proposal for the implementation of CFI-icall [1] with ThinLTO. Jumptables are generated in the merged module. To generate a jumptable, we need a list of functions with !type annotations, including (in non-cross-dso mode) external functions. Unfortunately, LLVM IR does not preserve unused function declarations, and we don’t want to copy the actual function bodies to the merged
