Hi everybody,
I know that this may be a very silly question, but seriously, I'm totally lost.
So, what I want to know is how from my Module I can get MachineFunctions or MachineBasicBlocks.
I'm able to read a file with LLVM IR, create the Module and I also managed to create some passes for it, but what I want is to see the x86-64 assembly that this IR generates and map MachineBasicBlocks with BasicBlocks.
I know that I should follow the Instruction Selection steps from http://llvm.org/docs/CodeGenerator.html#using-the-machineinstrbuilder-h-functions, but I couldn't figure it out how to do this. I also tried to read the llc's code, but it didn't help me so much.
I would be grateful if somebody show me an example of how from a Module I can get MachineBasicBlocks.
Thank you,
