There's a few relevant forward declarations in there that may require downstream adding explicit includes: llvm/MC/MCContext.h no longer includes llvm/BinaryFormat/ELF.h, llvm/MC/MCSubtargetInfo.h, llvm/MC/MCTargetOptions.h llvm/MC/MCObjectStreamer.h no longer include llvm/MC/MCAssembler.h llvm/MC/MCAssembler.h no longer includes llvm/MC/MCFixup.h, llvm/MC/MCFragment.h Counting preprocessed lines required to rebuild llvm-project on my setup: before: 1052436830 after: 1049293745 Which is significant and backs up the change in addition to the usual benefits of decreasing coupling between headers and compilation units.
