Thanks for the clarification and for the links. I see — since GCC 13.5 is the final release on the gcc-13 branch and the branch will be closed afterward, I won’t pursue this backport for gcc-13 upstream.
I’ll keep this change in our local toolchain packaging as needed, and I’ll only repost upstream if there is any new fix or test coverage relevant to active branches.
