Medhi, here is the patch that uses a static function. Does it look OK?

As for your question about the two-step promotion: Yes, this produces the same result if we only do the promotion in LTO optimization. The intra-module promotion will stop at the first target that it cannot promote and write the remaining VP targets to the metadata. The cross-module promotion will pick it up and do the rest.

Thanks!
