v8 llvm backend

[林作健]

Hi
JSC boosts by more than 50% performance using LLVM. Does v8 guys have considered moving to LLVM by replacing current lithium backend?

[Andreas Rossberg]

LLVM is not a suitable replacement for Crankshaft, because it is far too slow to be usable as a second tier jit compiler (JSC uses it as 4th tier).

Our replacement for Crankshaft is the new Turbofan compiler the V8 team is currently working on, which we believe to be a much better fit for JavaScript.
