Description Victor Shoup 2018-07-21 16:58:59 UTC 
Input file GGG.cpp:
struct X;
void h(X&,X&);
inline void h(X&,int) {}
__attribute__((noinline)) void h(X&,X&)  {}

Command line: g++ -c GGG.cpp

Output: 
GGG.cpp:4:32: warning: declaration of 'void h(X&, X&)' with attribute 'noinline' follows inline declaration [-Wattributes]
 __attribute__((noinline)) void h(X&,X&)  {}
                                ^
GGG.cpp:3:13: note: previous definition of 'void h(X&, int)' was here
 inline void h(X&,int) {}

Commentary:
This warning seems incorrect.  
Previous versions of GCC do not emit this warning, even with -Wall -Wextra.
