/llvm-project-20170507

Primary LanguageC++

Goals:

  • Run no python code at gn gen time, for speed
  • Source files are listed right in the gn files; use gn/sync_source_lists_from_cmake.py to keep the in sync after pulling

Missing:

  • monorepro "projects to build" selection mechanism
  • actual compiler flags (dead code stripping, warnings, etc)
  • optimized tablegen in debug builds (having an add_tablegen template might make sense now that there's llvm-tblgen and clang-tblgen)
  • describe how to get or build a gn binary
  • Probably want small feature headers for the feature config toggles, and per-platform defaults instead of configure for things like headers to use. (e.g. llvm_have_xar only used by llvm-objdump?)
  • cross build
  • bootstrap build
  • a better place to put the main gn config; new folder in monorepro isn't great
  • maybe a plan for non-monorepos?
