--- Comment #1 from Richard Smith <richard-llvm at metafoo.co.uk> ---
Clang follows the GCC specification for inline assembly. See
https://gcc.gnu.org/onlinedocs/gcc/Basic-Asm.html#Basic-Asm:

"""
Under certain circumstances, GCC may duplicate (or remove duplicates of) your
assembly code when optimizing. This can lead to unexpected duplicate symbol
errors during compilation if your assembly code defines symbols or labels.
"""

So this is a bug in the code.
