[LLVMdev] ARM ELF target and the use of VFP/NEON instructions

Hi,

I have submitted a bug some time ago to LLVM bugtracker:
http://llvm.org/bugs/show_bug.cgi?id=8931

The problem is that I'm trying to use clang in linux system, running
on ARM hardware. And this bug, as trivial as it is, seems to be a major
showstopper.

I wonder if I'm the only one trying to use LLVM/clang in this configuration
or doing something in an unusual way? Anyway, the LLVM sources contain a
comment "// FIXME: Emit FPU type", implying that emitting FPU type was
actually planned.

Would it be possible to fix this problem somehow? Being able to use clang
in linux on ARM systems may provide additional testing coverage, so should
be beneficial for LLVM project in the long run.

Thanks.
