Xtensa cores may or may not have hardware support for unaligned memory access. Remove TARGET_ALIGNED_ONLY=y from all xtensa configurations and pass MO_ALIGN in memory access flags for all operations that would raise an exception. Simplify use of gen_load_store_alignment by passing access size and alignment requirements in single parameter. Drop condition from xtensa_cpu_do_unaligned_access and replace it with assertion. Add a test.

Changes v2->v3: - drop assertion for !XTENSA_OPTION_HW_ALIGNMENT from xtensa_cpu_do_unaligned_access to correctly handle acquire/release intsructions; - add tests for acquire/release instructions. Changes v1->v2: - correctly handle case of !XCHAL_UNALIGNED_*_EXCEPTION in the test default-configs/targets/xtensa-linux-user.mak | 1 - default-configs/targets/xtensa-softmmu.mak | 1 - .../targets/xtensaeb-linux-user.mak | 1 - default-configs/targets/xtensaeb-softmmu.mak | 1 - target/xtensa/helper.c | 13 +- target/xtensa/translate.c | 120 +++++----- tests/tcg/xtensa/test_load_store.S | 221 ++++++++++++++++++ 7 files changed, 288 insertions(+), 70 deletions(-) create mode 100644 tests/tcg/xtensa/test_load_store.S
