The test scans for "const_int 0" in the RTL dump, but stack protector
can produce more "const_int 0". To avoid a failure with
--enable-default-ssp, disable stack protector for this.
gcc/testsuite/ChangeLog:
* gcc.target/aarch64/auto-init-7.c (dg-options): Add
-fno-stack-protector.
/* Verify zero initialization for array, union, and structure type automatic variables. */
/* { dg-do compile } */
-/* { dg-options "-ftrivial-auto-var-init=zero -fdump-rtl-expand" } */
+/* { dg-options "-ftrivial-auto-var-init=zero -fdump-rtl-expand -fno-stack-protector" } */
