llvm dev - Jul 2010 - [LLVMdev] llvm-gcc : Did not get a target machine! Triplet is mips64el-unknown-linux-gnu

Hi all,
   I met this error(title) when i was trying to compile llvm-gcc-4.2-2.7 on
loongson2f,a mips compatible platform.I also failed to build a
 cross-compiler and the error message was the same . Is that means llvm-gcc
cannot support mips back-end now?
   Thanks.

Here is my configure options:
$export TARGET=mips64el-unknown-linux-gnu
$../../src/llvm-gcc-4.2-2.7.source/configure --target=$TARGET
--prefix=$PREFIX --without-headers --disable-shared --disable-nls
--enable-checking --with-gnu-as --with-gnu-id --enable-languages=c,c++
--enable-llvm=$(pwd)/../llvm-2.7 && make all-gcc

I don't think that LLVM supports mips64 yet... Bruno?

There is some support for 64 bit fp, but not for mips64 though
