Volatile Loads/Stores

I'm trying to use volatile loads and stores like so:

#[inline(always)]
pub fn get_item(&self, offset: u32) -> T {
    unsafe {
        let ptr = self
            .items
            .get_unchecked(((self.start_ticket + offset) % self.max_capacity) as usize);
        core::ptr::read_volatile(ptr)
    }
}

#[inline(always)]
pub fn set_item(&mut self, offset: u32, item: T) {
    unsafe {
        let ptr = self
            .items
            .get_unchecked_mut(((self.start_ticket + offset) % self.max_capacity) as usize);
        core::ptr::write_volatile(ptr, item);
    }
}

But when compiling I get an error saying this is not supported yet.

error: store_with_flags is not supported yet: MemFlags(VOLATILE)

  2180 |         intrinsics::volatile_store(dst, src);
       |         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

It would be very useful to be able to specify this in loads. It seems like its possible in SPIRV using Memory Operands is there any way to do this currently?

Start with the reported core/src/ptr/mod.rs call to intrinsics::volatile_store and trace how Rust-GPU lowers volatile loads and stores to SPIR-V. Compare that path with the SPIR-V Memory Operands mentioned in the issue; done means the requested volatile operations are supported without the reported MemFlags(VOLATILE) error.
