Hello, Gentle ping for
https://gcc.gnu.org/ml/gcc-patches/2019-12/msg01398.html I realize and certainly understand that this is of lower importance than other matters currently being discussed on the lists. It's just that the end of stage 3 is imminent and I thought we'd better at least agree on a way forward before it closes. This particular change is an extraction of an hopefully non controversial part of a more general change discussed earlier. No ABI concern here. Thanks in advance!
