llvm dev - Sep 2010 - [LLVMdev] Any plans to add LLVM support for ARM EH EABI ?

I am new to LLVM but have perused the code alongside using llvm-gcc
and CLANG to build ARM EABI objects.

Based on this superficial analysis it appears that LLVM currently does
not support the ARM Exception Handling ABI (as defined under the
EABI).

Can anyone comment on whether plans are in place to remedy this?
I did see the discussion regarding work on the MC for ARM. Will this
work include emitting the exception handling code/tables compliant to
ARM's EH ABI?

Thanks,

-Dennis

Probably not at first. It may require discussions with the specific
front end folks (clang, llvm-gcc et al).

Thanks for bringing it up tho.,

Thanks Jason. 

Is it safe to say the MC work provides a (new) foundation for
implementing ARM EH? Or, is providing ARM EH independent of the ARM-MC
work?
