+	PR testsuite/53397
+	* gcc/testsuite/gcc.dg: Remove test cases pr53397-1.c and pr53397-2.c
+	they are moved to gcc.target/i386 as they are specific to i386/x86_64.
+	* gcc/testsuite/gcc.target/i386/pr53397-1.c: New test 
+	Checks we are prefetching for loop invariant steps
+	* gcc/testsuite/gcc.target/i386/pr53397-2.c: New test
+	Checks we are not prefetching for loop variant steps
