thanks Evan, I have just started writing td files. Any ideas how do I describe instructions for an accumulator based machine. The other pecularity is that we do not want to have any software stack. So the instructions like load and store have no meanings. In that case, how do I lower instructions that operate on stack frame? TIA, Sanjiv On 11/26/07, Evan Cheng <evan.cheng at apple.com>

Thanks again. One more question here: Since the regalloc works once per function, do I stil have access to the Call graph? Just saving information between regalloc passes for different functions may not be enough for my case. I will need to maintain the regalloc info of various passes in the call graph order. Anyways thanks for your inputs. I will get back if I need to learn more. Sanjiv On Nov

Could anybody guide me what information do I need to know about my target in order to provide the target lowering info to the llvm DAG generator? We do not have any fixed registers for argument passing. Everything including the formal and actual arguments will take part in a global interprocedural regalloc. Any pointers to learn about this will be a great help. Sanjiv

Hi Mikhail, Thanks for your wonderful help so far. I have few more questions to ask: How do I modify the driver to pick tools from where the driver itself resides, rather than from the PATH? And how to make sure that we have same behavior on Windows as far as paths (/ Vs \) and picking up tools from the driver directory is concerned? Do I need to write some C++ code to customize such

But why the cmp libcalls have to return a 32-bit value. e.g. Our libcall for comparing two floats is char _eq_f32 (float a, float b); rather than long
