+\* Ascend Graph capture and replay require the runtime `aclmdlRI*` symbols
+(`aclmdlRICaptureBegin`, `aclmdlRICaptureGetInfo`, `aclmdlRICaptureEnd`,
+`aclmdlRIExecuteAsync`, and `aclmdlRIDestroy`). The Graph replay test is
+registered for Ascend builds and passes on CANN 9.0 with 910B hardware. On a
