Hi There ,
I just started working on this issue https://youtrack.jetbrains.com/issue/KT-69082
and needed some help for identifying the problem , I just made a grep on IrElement with mutableMapOf and i found something like this
private val filteredElementEndsLV = mutableMapOf<IrElement, BitSet>()
but don't really know to to migrate this map of IR element to IR attribute
after some searching on this , i found that i can do something like this
private val filteredElementEndsLV = mutableMapOf<IrAttributeContainer, BitSet>()
could you help me understanding this task , I'm preparing for GSoC 2025 and I think this might be helpful.
Thank you in advance!

Hi!
The task is to replace such maps with irAttribute() based extension properties. Please check.docs on `irAttribute`/`irFlag` and commits that mention either KT-69082 or KT-69083 to see how it was done before.

Also note that IrAttrubuteContainer is de-facto removed, and it doesn't relate much to the "attributes" in question.
