Hi everyone I am still in the process of upstreaming some improvements to the embed bitcode option. If you want more background, you can read the previous RFC (http://lists.llvm.org/pipermail/llvm-dev/2016-February/094851.html <http://lists.llvm.org/pipermail/llvm-dev/2016-February/094851.html>). This is part II of the discussion. Current Status: A basic version of -fembed-bitcode option is upstreamed and functioning. You can use -fembed-bitcode={off, all, bitcode, marker} option to control what gets embedde...

From the RFC <http://lists.llvm.org/pipermail/llvm-dev/2016-February/094851.html>, and reading through the implementation, I'm piecing together that the goal was to enable capturing IR right after clang and before passing it to LLVM's optimization passes, as well as the command line options needed for later compiling that IR to the same native object it was comp...

...n one thread which is then suspended and continued on a different thread. This is apparently a known issue, covered by [PR19177](https://llvm.org/bugs/show_bug.cgi?id=19177). * Steven Wu has posted an [RFC on embedding bitcode in object files](http://lists.llvm.org/pipermail/llvm-dev/2016-February/094851.html). The intent is to upstream support that already exists in Apple's fork. Understandably some of the respondents asked how this relates to the .llvmbc section that the Thin-LTO work is introducing. Steven indicates it's pretty much the same, but for Mach-O rather than ELF and that he ho...
