--- Comment #10 from Jakub Jelinek <jakub at gcc dot gnu.org> --- (In reply to Bruno Haible from comment #9) > We need only to see that the compilation unit only ever accesses > html5[i].name and html5[i].value but never html5[i] as an entire struct. I > don't think any knowledge about strcmp is needed. No, even from escaped pointer to subobject you can create pointer to the whole object and access it.
