Kostya, do you remember the exact original case in glibc for 22830 and what glibc change fixed it? I vaguely recall the case, but not enough to find the actual change and compare it to the new scenarios. I suspect that the original case was easy to fix because it was just that the hidden_proto

Thanks for checking, Nick! +Roland, FYI (recent changes in clang break compilation of all of the glibc), similar to https://llvm.org/bugs/show_bug.cgi?id=22830#c1 On Mon, Jan 4, 2016 at 3:21 PM, Nick Lewycky wrote: > On 01/04/2016 01:40 PM, Kostya Serebryany wrote: > >> >> >>

I am now observing this error message when building glibc with clang (from trunk): ../include/string.h:101:28: error: cannot apply asm label to function after its first use libc_hidden_builtin_proto (memcpy) (many more instances) Do you think this is a bug in glibc code, or the error message
