I see 2 failing packages: 1) xf86-video, it uses https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71991#c0 Thus it will be fixed. 2) xen It contains: cat fuzz-emul.i __attribute__((__always_inline__)) a() {} #pragma GCC target "no-sse" b() { a(); } Where 'a' is 'memcpy' and 'b' is a function in xen. Can you Honza also take a look r251333 where we started to reject such code?
