Whether the address mapping function is supported

[chen4s666]

Hello, in the source code and tests, I can see that the resolution of AT identifiers is already supported, but when I actually use them, they don't seem to be used correctly. Am I using it incorrectly, or is the feature still under development? If it is still under development, is there any plan for it? Thank you.
Here is the ST code I wrote, and the ir code I generated. You can see that there is no difference between the two variables I defined, and you can't see where AT %MW1 is represented.

PROGRAM main
	VAR
	xx AT %MW1:INT;
	yy :INT;
	END_VAR
	yy:=xx;
END_PROGRAM

%main = type { i16, i16 }

@main_instance = global %main zeroinitializer

define void @main(%main* %0) section "fn-main:v" {
entry:
  %xx = getelementptr inbounds %main, %main* %0, i32 0, i32 0
  %yy = getelementptr inbounds %main, %main* %0, i32 0, i32 1
  %load_xx = load i16, i16* %xx, align 2
  store i16 %load_xx, i16* %yy, align 2
  ret void
}

Hello chen, this is something we still did not implement.
We added the hardware address support to be able to compile projects that use them without any errors but we don't yet do anything with the address. This is however planned for the coming few months.

Thank you, this is a very convenient feature.
