[llvm-dev] announcing an *early preview* of a cross-referencing code search website for LLVM

[Peter Collingbourne via llvm-dev]

Thanks. I was aware of DXR, but I didn't know that they were using Clang.
Kythe uses a similar approach, but there's no need to actually build the
whole project, you just need a compilation database [1]. In LLVM's case, I
need to arrange to build all the tablegen'd files upfront, and I have a
hacky script that does so by parsing the "ninja -t commands" output.
