+------------------
+Could we use LLVM?
+------------------
+
+In theory yes. But we tried to use it 5 or 6 times already, as a
+translation backend or as a JIT backend --- and failed each time.
+
+In more details: using LLVM as a (static) translation backend is
+pointless nowadays because you can generate C code and compile it with
+clang. (Note that compiling PyPy with clang gives a result that is not
+faster than compiling it with gcc.) We might in theory get extra
+benefits from LLVM's GC integration, but this requires more work on the
+LLVM side before it would be remotely useful. Anyway, it could be
+interfaced via a custom primitive in the C code.
+
+On the other hand, using LLVM as our JIT backend looks interesting as
+well --- but again we made an attempt, and it failed: LLVM has no way to
+patch the generated machine code.
+
+So the position of the core PyPy developers is that if anyone wants to
+make an N+1'th attempt with LLVM, he is welcome, and he will receive a
+bit of help on the IRC channel, but he is left with the burden of proof
+that it works.
