this patch - https://reviews.llvm.org/D110337 changes the way how hostcall hidden argument is emitted for printf, but the sanitized kernels also use hostcall buffer to report a error for invalid memory access, which is not handled by the above patch and it leads to vdi runtime error: Device::callbackQueue aborting with error : HSA_STATUS_ERROR_MEMORY_FAULT: Agent attempted to access an inaccessible address. code: 0x2b Patch by: Praveen Velliengiri Reviewed by: Yaxun Liu, Matt Arsenault Differential Revision: https://reviews.llvm.org/D112820
