gcc/ChangeLog:
PR target/115978
* config/i386/driver-i386.cc (host_detect_local_cpu): Enable
APX_F only for 64-bit codegen.
* config/i386/i386-options.cc (DEF_PTA): Skip PTA_APX_F if
not in 64-bit mode.
gcc/testsuite/ChangeLog:
PR target/115978
* gcc.target/i386/pr115978-1.c: New test.
* gcc.target/i386/pr115978-2.c: Ditto.
