Hy all, I've already received a couple of messages from pkg-fallout about build failure on head-i386-default [1] [2] both pointing to the same errors, about missing intrinsic symbols related to __atomic_* The clang documentation about C11 atomic builtins [3] stats that __atomic_* are GCC extension and Clang provides them. It seems to me that this specific GCC-compatible builtin are enabled on amd64, but not on i386. Is there a way to enable GCC compatible __atomic_ builtin also on i386? Or should I provide patches to adopt _c11_atomic_* instead of __atomic_* for every ports that need it ? Thanks in advance!
