I read it, and is not that bad, in fact the points it make are probably as close as non-controversial in how make a fast compiler. And LLVM is certainly major slow in the compiling pipeline. And very complex at it. What is unclear is how design "a photoshop-like plugin architecture" that allow to do all the optimizations it have, ie: How much the complexity of LLVM is related to the need to intermix all the optimizations and IF is possible to modularize them to the extend to make a lean core? (A better way to say the same is that it must be. like the nano pass framework, that it have more pedigree in this case than use of photoshop :;)
