progress. Not yet working.<br>

However, the error message you've posted makes it appear that the
x86 version of the assembler is being called instead of the ARM
one. No doubt since it is a 3.4 kernel it doesn't have all the
appropriate patches in place since we spend a lot more time on the
mainline patches.<br>
<br>
Cross posting to the LLVMLinux list so that others who are
interested might be able to help you.<br>

Depending on which kernel version you are building, you will
need a clang newer than 3.5. Currently only the pre 3.6
clang will work.<br>

I'd have to see the error. But remember that the kernel
can't use floating point opcodes (with very few exceptions).<br>

Like I said, I'd need to see the error. I don't have enough
info to be able to even guess.<br>
