Issue is related to option -fasynchronous-unwind-tables option. Better said to
option -fasynchronous-unwind-tables without -funwind-tables.
Following sample can demonstrate issue pretty well:
'#include intrin.h
int a;'
By compiling test by '$ x86_64-w64-mingw32-gcc -S -o t.s t_xmmintrin.c -O2
-fasynchronous-unwind-tables' I can reproduce the fentry message.
By removing option -fasynchronous-unwind-tables, or adding -funwind-tables
option message won't be displayed.
By following patch for me the issue is solved:

Issue is that for SEH-target we need to generate dw2 unwind-information so that
-fasynchronous-unwind-tables works proper.
Following patch should fix that:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57897 --- Comment #3 from Kai Tietz ktietz at gcc dot gnu.org --- Hmm, what I don't get is why there is a warning about -mno-fentry. So I would assume there is something else broken. Nevertheless this reminds me about pr/57848. This issue seems to be in general no mingw specific problem, but more an inconsistency about sse and builtins.
