llvm dev - Oct 2013 - [LLVMdev] Runtime optimizer

Hello,

Please, I need more information on the runtime optimizer used in the LLVM
JIT.

-          Where can I find it in the LLVM source code?

-          Are those runtime optimizations done on the LLVM representation
code or on the machine code?

Hi Sara,

Take a look at LLVMTargetMachine::addPassesToEmitMachineCode() in
lib/CodeGen/LLVMTargetMachine.cpp for the old JIT engine or
LLVMTargetMachine::addPassesToEmitMC() in the same place for MCJIT.
