[LLVMdev] MIPS n64 ABI and non-PIC
Has anyone experimented with generating non-PIC for MIPS64 and the n64 ABI? Currently MipsISelLowering.cpp uses conditions like: if ((getTargetMachine().getRelocationModel() == Reloc::PIC_) || IsN64) { } around any PIC code generation. Is generating non-PIC just untested, or is it known not to work? I can't find any discussion of it anywhere. I ran into this when trying to see why
