I didn't rewrite attribute "arm-long-calls" in the IR in ARMISelLowering.cpp because MachineFunction::Fn is a pointer to a constant. Also, I thought "arm-long-calls" should be handled in lib/Target/ARM since it is an ARM-specific option, and hence didn't rewrite it in llc.cpp as I did to allow overriding "target-cpu" and "target-features" (those are target-independent options).

Did I understand your question correctly?
