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? Dear Bug Submitter, This bug has been in NEEDSINFO status with no change for at least 15 days. Please provide the requested information as soon as possible and set the bug status as REPORTED. Due to regular bug tracker maintenance, if the bug is still in NEEDSINFO status with no change in 30 days the bug will be closed as RESOLVED > WORKSFORME due to lack of needed information.

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: ???

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: ???
