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?

Inizia dalla chiamata a intrinsics::volatile_store segnalata in core/src/ptr/mod.rs e traccia il modo in cui Rust-GPU abbassa i load e gli store volatile a SPIR-V. Confronta questo percorso con gli SPIR-V Memory Operands menzionati nell’issue; il lavoro è completo quando le operazioni volatile richieste sono supportate senza l’errore segnalato MemFlags(VOLATILE).
