+Ideas for things to do:
+
+- more projects (compiler-rt libcxx libcxxabi libunwind clang-tools-extra lldb)
+  - phosek expressed interest in compiler-rt libcxx libcxxabi libunwind
+  - once there are more projects, have an llvm_enable_projects arg, modeled
+    after llvm_targets_to_build in the GN build
+- more targets (AVR MIPS RISCV SystemZ etc)
+  - example: https://reviews.llvm.org/D56416
+- investigate feasibility of working `gn check`
+
+- "optimized tblgen" mode
+  - either just always build tablegen and support with opt config
+  - or use opt toolchain and build tablegen twice in debug builds, like cmake
+
+- cross builds using GN's toolchain feature
+- one-build-dir bootstrap builds using GN's toolchain feature
+
+- move clang_tablegen into lib/ for private files
+- add write_cmake_config() template, use it throughout where
+  write_cmake_config.py is called
+- add dead code stripping
+- move run_tablegen.py from build to tablegen folder
+- figure out why -Iclang/Support gets added so often
+- make LLVM_LIBXML2_ENABLED use llvm_canonicalize_cmake_boolean (cf D28294),
+  clean up both GN and CMake builds
+- plugin() template with working rpath, exports thingers
+  - then port clang_build_examples and enable by default so that clang
+    plugin tests run by default
+- plugin_host() template
