This patch seems mostly plausible, though there are various places that call targetm.libc_has_function with and empty string as second argument, that should be naming the specific function instead. I haven't reviewed the details, and at this development stage I think it will need to wait until after 4.8 branches. -- Joseph S. Myers jos...@codesourcery.com
