I am building the application on QNX and running those applications on R-CAR s4 board. Valgrind is integrated with my image. When I run the applications on the target platform, I am facing the below issue. ==417838== Memcheck, a memory error detector ==417838== Copyright (C) 2002-2017, and GNU GPL'd, by Julian Seward et al. ==417838== Using Valgrind-3.14.0 and LibVEX; rerun with -h for copyright info ==417838== Command: ./bin/fusion ==417838== ARM64 front end: load_store disInstr(arm64): unhandled instruction 0x88E1FC02 disInstr(arm64): 1000'1000 1110'0001 1111'1100 0000'0010 ==417838== valgrind: Unrecognised instruction at address 0x17e88. ==417838== at 0x17E88: ??? (in /proc/boot/ldqnx-64.so.2) ==417838== Your program just tried to execute an instruction that Valgrind ==417838== did not recognise. There are two possible reasons for this. ==417838== 1. Your program has a bug and erroneously jumped to a non-code ==417838== location. If you are running Memcheck and you just saw a ==417838== warning about a bad jump, it's probably your program's fault. ==417838== 2. The instruction is legitimate but Valgrind doesn't handle it, ==417838== i.e. it's Valgrind's fault. If you think this is the case or ==417838== you are not sure, please let us know and we'll try to fix it. ==417838== Either way, Valgrind will now raise a SIGILL signal which will ==417838== probably kill your program. ==417838== ==417838== Process terminating with default action of signal 4 (SIGILL): dumping core ==417838== Illegal opcode at address 0x17E88 ==417838== at 0x17E88: ???

Thank you !
Please use a version of Valgrind that is more recent. 3.14 is old. I believe that the CAS instruction that you have a problem with was added in Valgrind 3.16.1. Can you please confirm that it works with a recent more Valgrind?
