--- Comment #1 from Martin Sebor <msebor at gcc dot gnu.org> ---
This sounds a like a useful feature, not just to improve code generation but
also to help avoid false positives when -Wuninitialized is enhanced to
understand allocated memory. For the latter, the attribute should also make it
possible to indicate whether the memory is zeroed out or just initialized to
some possibly non-zero values. Confirmed.
