FWIW, We tried to implement this 5 years ago https://gcc.gnu.org/pipermail/gcc-patches/2019-November/534518.html
and you'll likely get the same feedback if you aren't already doing so.

I think Richard would prefer to have a general framework these kinds of operations.  We never got around to doing so
and it's still on my list but if you're taking care of it 😊

Just though I'd point out the previous feedback.

Cheers,
