Subject: LLVM JIT and PGO in JIT

Hi,

I haven't touched LLVM codes for many years. I have a few questions related
to LLVM JIT and PGO in JIT:
1) Is LLVM JIT method-based or trace-based JIT?
2) How does LLVM do gear shift from the interpreter mode to the JIT mode?
3) Any profiling mechanism implemented in LLVM JIT?
4) Any profile-guided optimization implemented in LLVM JIT?

thanks
Qiong
