Is there a lto support in MLIR?

Is there a lto support in MLIR? OR has some one started an effort in this regard?

thanks,

I don’t think there is anything like, but this is also because LTO is very specific to the linker semantic: it isn’t clear to me that there is a lot of “LTO” specific aspect in MLIR that generalizes.
What do you have in mind?
