Can LLVM emit machine code faster with no optimization passes?
Hello,
Recently Jonathan Blow posted a short screencast discussing build time of
his compiler with when no optimizations are run on the user's code.
Part 1: https://www.youtube.com/watch?v=HLk4eiGUic8
Part 2: https://www.youtube.com/watch?v=mIjGYbol0O4
He discusses what parts are taking the longest to compile, and the
ultimately shows this:

...which shows that emitting LLVM IR in memory and
LLVMTargetMachineEmitToFile is the bottleneck in his compiler toolchain.
In fact, it was significantly faster to emit C to di...
