testsuite: XFAIL some Wstringop-overflow tests ...
... for targets that support vectorization of 2-byte char stores with unaligned address at plain O2. 2021-12-31 Uroš Bizjak <ubizjak@gmail.com> gcc/testsuite/ChangeLog: * lib/target-supports.exp (check_vect_slp_store_usage): Handle TEST_V2QI_2. (check_effective_target_vect_slp_v2qi_store_unalign): New procedure. * c-c++-common/Wstringop-overflow-2.c: XFAIL specific tests for vect_slp_v2qi_store_unalign targets. * g++.dg/warn/Wstringop-overflow-3.C: Ditto. * gcc.dg/Wstringop-overflow-28.c: Ditto. * gcc.dg/Wstringop-overflow-68.c: Ditto. * gcc.dg/Wstringop-overflow-75.c: Ditto. * gcc.dg/Wstringop-overflow-76.c: Ditto.
