registerSection should only be called by MCObjectStreamer::changeSection. This will be utilized by a pending change to move initial fragment allocation from MCContext::createSection to MCStreamer::changeSection, resolving some issues (Fragments should only be created when using MCSteramer, not during `MCContext::getELFSection` calls) Pull Request: https://github.com/llvm/llvm-project/pull/150183
