Based on the output of include-what-you-use. This is a big chunk of changes. It is very likely to break downstream code unless they took a lot of care in avoiding hidden ehader dependencies, something the LLVM codebase doesn't do that well :-/ I've tried to summarize the biggest change below: - llvm/include/llvm-c/Core.h: no longer includes llvm-c/ErrorHandling.h - llvm/IR/DIBuilder.h no longer includes llvm/IR/DebugInfo.h - llvm/IR/IRBuilder.h no longer includes llvm/IR/IntrinsicInst.h - llvm/IR/LLVMRemarkStreamer.h no longer includes llvm/Support/ToolOutputFile.h - llvm/IR/LegacyPassManager.h no longer include llvm/Pass.h - llvm/IR/Type.h no longer includes llvm/ADT/SmallPtrSet.h - llvm/IR/PassManager.h no longer includes llvm/Pass.h nor llvm/Support/Debug.h And the usual count of preprocessed lines: $ clang++ -E -Iinclude -I../llvm/include ../llvm/lib/IR/*.cpp -std=c++14 -fno-rtti -fno-exceptions | wc -l before: 6400831 after: 6189948 200k lines less to process is no that bad ;-) Discourse thread on the topic: https://llvm.discourse.group/t/include-what-you-use-include-cleanup Differential Revision: https://reviews.llvm.org/D118652
