--- Comment #3 from Daniel Sanders <daniel.sanders at imgtec.com> ---
It still fails for me on current trunk. It triggers the N32/N64 on a mips-*
triple assertion which will take a while to fix (it needs the
Triple->TargetTuple project to finish) to be fixable. You could work around it
using -march=mips2. This should produce what you want except the ELF header
will say mips2 rather than mips3.

clang:
/mnt/scratch/das/llvm-upstream/llvm.src/lib/Target/Mips/MipsSubtarget.cpp:94:
llvm::MipsSubtarget::MipsSubtarget(const llvm::Triple&, const string&, const
string&, bool, const llvm::MipsTargetMachine&): Assertion `((!isGP64bit() &&
(isABI_O32() || isABI_EABI())) || (isGP64bit() && (isABI_N32() ||
isABI_N64()))) && "Invalid  Arch & ABI pair."' failed.
