This fixes the rather new tests cmp-mem-const-{1,2,3,4,5,6}.c for sparc.
For -1 and -2 we need at least optimization level 2 on sparc. For the
sake of homogeneity, change all test cases to -O2. For -3 and -4 we do
not end up with a comparison of memory and a constant, and finally for
-5 and -6 the constants are reduced by a prior optimization which means
there is nothing left to do. Thus excluding sparc from those tests.
Ok for mainline?
gcc/testsuite/ChangeLog:
PR rtl-optimization/110869
* gcc.dg/cmp-mem-const-1.c: Use optimization level 2.
* gcc.dg/cmp-mem-const-2.c: Dito.
* gcc.dg/cmp-mem-const-3.c: Exclude sparc from this test.
* gcc.dg/cmp-mem-const-4.c: Dito.
* gcc.dg/cmp-mem-const-5.c: Dito.
* gcc.dg/cmp-mem-const-6.c: Dito.
