[LLVMdev] Can I add GlobalVariable in MachineFunctionPass ?
Hello, I want to add a global variable of arrayType in my MachineFunctionPass. However, I only get const Module from MachineFunction.getMMI().getModule(). I can't add any global variable to a const Module. Another way is to add a global variable in doInitialization in my MachineFunctionPass, but I can't determine the size of my arrayType for global variable in doInitialization. Is there any suggestion that can help me achieve this? Thanks in advance.

Antony, What are you trying to accomplish in this case? I did something very similar in the AMDIL backend, but it was not the cleanest solution and you are correct it has to be do at doInitialization stage and not at runOnMachineFunction.

Micah, As you expected, I am trying to create local memory but in the NVPTX backend. It's really not convenient that I can't create local memory in runOnMachineFunction. Hmm.... Since I should do it at doInitialization stage, I also need to do some tricks in global variable and AsmPrinter to resize it. Did you use the similar way?
