Naga's SPIR-V frontend does not currently handle atomic operations. Using an atomic operation (in this case spirv_std::arch::atomic_i_increment in a rust-gpu shader) leads to a parse error:

UnsupportedInstruction(Function, AtomicIIncrement)

I'm treating this as the tracking issue for adding atomics to the spv frontend.

I've submitted a proposal to NLNet to fund this issue. If they accept my proposal I'll likely pick this up after the holidays.
