The conflicts that show up from time to time *also* inconvenience users, and that is an ongoing inconvenience. > .text%name does not address -fno-unique-section-names. And neither does ".text.name.". Something like this is a prerequisite of such an option. Also, please use a different name, one that does not start with "no-"? It isn't about unique names at all anyway, it is about having multiple sections with the same name (that then can get separately GCed, because of new linker features). Segher
