llvm dev - Mar 2008 - [LLVMdev] Compiling llvm-gcc on amd64 with 32 bits: assembler still carps

To clarify,

configure --host=i686-pc-linux-gnu --target=i686-pc-linux-gnu
--target=i686-pc-linux-gnu

I do this all the time on my 4 core amd64 box and it works fine.

There must be some other difference, as I'm doing exactly that:

Look at how $LLVM_CONFIGURE is built, the final value is

--prefix=/home/jo --enable-optimized --build=i686-pc-linux-gnu
--host=i686-pc-linux-gnu --target=i686-pc-linux-gnu"

This looks likes its missing some stuff. Make sure the configure line  
is exactly as what is in README.LLVM.
