Hi all, we have several features in Mips that are dependent on target abi. A recent commit(r224492) introduced a new -target-abi option to TargetOptions struct that provides access to abi string. This info is stored in MCSubtarget class(ARMSubratget in this case) and distributed to other libraries. Unfortunately, for Mips we need this info in other classes that don't have access to MCSubtarget class, like MCAsmBackend and MCTargetStreamer and instantiating a new copy od TargetOption causes link errors as it is already i...

...bjectWriteris used for direct object output whether directly from the codegen or from the llvm-mc assembler. The grand idea was to use MipsSubtarget because it has almost everything I need, but the big glitch is that is only used by llc and when used directly by llvm-mc, we only get the base class MCSubtargetInfo. AsmPrinter has access to the codegen variation (<target>Subtarget) and thus doesn't have this issue. Is the answer for every create<target>MCSubtargetInfo() call to mimic <target>TargetMachine and create a <target>Subtarget? This would give a target a common class...
