llvm dev - Sep 2009 - [LLVMdev] Registering a MachineFunctionPass to JIT codegen

Hi all,

I can't find a way to add a MachineFunctionPass to the common codegen 
passes (LLVMTargetMachine::addPassesToEmitMachineCode) while JITting 
(the pass manager is associated with the jitstate of the JIT and I can't 
access it because it's private). Have I missed something? Or adding a 
MachineFunctionPass to codegen requires to change the 
LLVMTargetMachine::addPassesToEmitMachineCode function?

Thanks,
Nicolas

You haven't missed anything, there isn't currently a way to do this.

Good to know. Anything against making the codegen pass manager 
accessible to users? Something like 
ExecutionEngine::getCommonCodegenPassManager() ?
