digitalmars.D.ldc - fyi: COMDAT linkage -> less LLVM optimization

We emit most functions in COMDAT sections, but with LLVM 3.9 we loose out on some optimizations: http://llvm.org/releases/3.9.0/docs/ReleaseNotes.html#changes-to-llvm-s-ipo-model Don't know what the impact will be. (I've always disliked putting everything in COMDAT sections, so it's extra ammunition against that) -Johan

Maybe compile to llvm IR, remove comdat attributes and compare assembler output?
