Hi all,
The tests added in gcc.dg/tree-ssa/isolate-*.c is failing for AVR target,
Because the isolate erroneous path pass needs -fdelete-null-pointer-checks
option to be enabled. For AVR target that option is disabled, this cause
the tests to fail. Following Patch skip the isolate-* tests if
"keeps_null_pointer_checks" is true.
