Description Christian 2019-09-25 20:16:23 UTC 
SUMMARY
I get the valgrind logs below when running our 32bit program on an x64_x86 platform. The code that is being run is a function from a statically linked secure library that tries to determine if we are running on virtualized hardware.

Sep 25 13:51:20 chrvmcd valgrind[20129]: vex x86->IR: unhandled instruction bytes: 0xF 0x3F 0x7 0xB
Sep 25 13:51:20 chrvmcd valgrind[20129]: ==20129== valgrind: Unrecognised instruction at address 0x9e35823.
....
Sep 25 13:51:20 chrvmcd valgrind[20129]: vex x86->IR: unhandled instruction bytes: 0xF 0xB 0x78 0x65
Sep 25 13:51:20 chrvmcd valgrind[20129]: ==20129== valgrind: Unrecognised instruction at address 0x9e3556d.



STEPS TO REPRODUCE
1. Invoke program with the command "/usr/bin/valgrind --tool=memcheck --undef-value-errors=no /sysro/mn3300lx"
2. 
3. 

OBSERVED RESULT
Get the error logs mentioned above and the function that was run returns an unexpected value. But the program continues to run.


EXPECTED RESULT
The function should return 2 in the success case. 


SOFTWARE/OS VERSIONS
Linux chrvmcd 3.10.0-957.21.3.el7.x86_64 #1 SMP Tue Jun 18 16:35:19 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

ADDITIONAL INFORMATION
Unfortunately we have only seen this error when running our program and so we don't have a reproduction scenario you could run.

Sep 25 16:09:15 chrvmcd valgrind[30125]: ==30125== did not recognise.  There are two possible reasons for this.
Sep 25 16:09:15 chrvmcd valgrind[30125]: ==30125== 1. Your program has a bug and erroneously jumped to a non-code
Sep 25 16:09:15 chrvmcd valgrind[30125]: ==30125==    location.  If you are running Memcheck and you just saw a
Sep 25 16:09:15 chrvmcd valgrind[30125]: ==30125==    warning about a bad jump, it's probably your program's fault.
Sep 25 16:09:15 chrvmcd valgrind[30125]: ==30125== 2. The instruction is legitimate but Valgrind doesn't handle it,
Sep 25 16:09:15 chrvmcd valgrind[30125]: ==30125==    i.e. it's Valgrind's fault.  If you think this is the case or

Comment 1 Julian Seward 2019-12-28 17:08:43 UTC 
0F 3F seems to me to be undefined, and 0F 0B is the normal UD2.  
So as far as I can see, V is behaving correctly.  

Given that your program continues to run, I'd guess it catches
the SIGILLs and continues.  It might be quieter if you give the
--sigill-diagnostics=no flag.
