According to the attached dump file, I believe the end of
attr-complex-method-2.c should look like this:
/* { dg-final { scan-tree-dump "__(?:gnu_)?divdc3" "optimized" { target { !=
 {
avr-*-* h8300-*-* } } } } } */

/* { dg-final { scan-tree-dump "__(?:gnu_)?divsc3" "optimized" { target {
avr-*-* h8300-*-* } } } } */

Similarly, shouldn't attr-complex-method.c also search for __divsc3 for AVR,
H8/300 and possibly a few other architectures?=
