--- Comment #5 from Florian Hahn <Florian.Hahn at arm.com> ---
llvm-mc from the current master produces thumb nops for the example:

t.o:    file format ELF32-arm-little

Disassembly of section .text:
       0:       00 44   add     r0, r0
       2:       00 bf   nop
       4:       00 bf   nop
       6:       00 bf   nop
       8:       00 44   add     r0, r0
