This avoids two more types of FAILs with the gnu_vector test case. First, for POWER targets newer GCCs emit an ABI note when invoked with "-mcpu=native". Then the test case fell back to non-native compile, producing code for a non-vector ABI. But that is not supported by GDB. Thus the compiler note is now suppressed with "-Wno-psabi". Second, on s390 the test case produced FAILs after falling back to a non-vector ABI when using "finish" or "return" in a vector-valued function. This was due to a long-standing known bug (Bug 8549). This case is now detected, and KFAILs are emitted instead. gdb/testsuite/ChangeLog: * gdb.base/gnu_vector.exp: Try compilation with "-mcpu=native -Wno-psabi" if "-mcpu=native" fails. For the tests with "finish" and "return" use KFAIL when GDB can not read/write the vector return value.
