Hi, the latest mlir emitc support `opaque type`, which we can use to generate self define struct like this.

```auto
!emitc.opaque<"MyStruct">

```

But how to access the struct member using `.`? The subscript operator only support `[]`

Hey @feiyulv,

This will be possible as soon as [[mlir][EmitC] Add member access ops by marbre · Pull Request #98460 · llvm/llvm-project · GitHub](https://github.com/llvm/llvm-project/pull/98460) lands which adds a `emitc.member` operation.
