TL;DR: I'm facing some problems trying to get LLVM to generate the code I want, please help me out if you can spare some time. It involves the SelectionDAG, MachinsInstr and liveness analysis portions. I'm currently trying to implement alloca correctly. It essentially boils down to checking if the current stack block has enough space to hold the alloca'ed block of memory.
