llvm dev - Dec 2009 - [LLVMdev] Register only Machine

Hi,

        Can LLVM support a machine has no memory? My machine has only
registers, how should I process load/store instructions?

I have tried to map the memory target to virtual register, but it will
assert whose message is “Register use before def!”

 

Thanks a lot

No, the machine model assumes you can do load and store for turing completeness.
You can support subsets of llvm, but not very useful subsets.
