[FPEnv][AArch64] Constrained FP this year?

Does anyone have any plans on working on constrained floating-point for the AArch64 backend this year? We’re willing to help out with the work as we can, and coordinating effort is a good thing. Anyone?

I have intention to implement some functionality on AArch64:

I gave the talk and proof of concept on using portable SIMD for libmvec at the last LLVM dev mtg[1] and pointed out that this could support constrained rounding modes (which the original libmvec spec leaves out, but is now in LLVM’s language ref). My work on this stopped after the conference and nobody wanted to pay me, but I would be available for consulting on this.
