This patch will resolve testsuite/gcc.dg/pr44194-1.c failure observed in

aarch64 target by refining the second scan-rtl-dump-not pattern.

For aarch64 target, the following barrier is generated which will
exactly match the current pattern
"insn \[^\n\]*set \\(mem". This is undesired. By adjusting the pattern,
this scenario is excluded.

(insn 29 28 30 (set (mem:BLK (scratch) [0  A8])
          (unspec:BLK [
                  (reg/f:DI 31 sp)
                  (reg/f:DI 29 x29)
              ] UNSPEC_PRLG_STK)) pr44194-1.c:10 704 {stack_tie}
       (nil))

Please use "scratch" instead of "stack_tie" as marker, it's more general.

Hi,

Any comments?

Kind regards,
