regcache::cooked_read unit test
This patch adds a unit test to regcache::cooked_read. This unit test is a little different from normal unit test, it is more about conformance test or interaction test. This test pass both raw register number and pseudo register number to regcache::cooked_read, in order to inspect 1) return value of cooked_read, 2) how are target_ops to_xfer_partial, to_{fetch,store}_registers called (because regcache is updated by means of these three target_ops methods). With this test here, we have a clear picture about how each port of GDB get cooked registers. This patch also shares some code on mock target. gdb: 2017-11-24 Yao Qi <yao.qi@linaro.org> * gdbarch-selftests.c (test_target_has_registers): Move it to target.c. (test_target_has_stack): Likewise. (test_target_has_memory): Likewise. (test_target_prepare_to_store): Likewise. (test_target_store_registers): Likewise. (test_target_ops): Likewise. * regcache.c: Include selftest-arch.h and gdbthread.h. (target_ops_no_register): New class. (test_target_fetch_registers): New. (test_target_store_registers): New. (test_target_xfer_partial): New. (readwrite_regcache): New. (cooked_read_test): New. (_initialize_regcache): Register the test. * target.c: (test_target_has_registers): Moved from gdbarch-selftests.c. (test_target_has_stack): Likewise. (test_target_has_memory): Likewise. (test_target_prepare_to_store): Likewise. (test_target_store_registers): Likewise. * target.h (test_target_ops): New class.
