[Valgrind-users] unhandle instruction with valgrind on armv8

[pritesh <pri...@gm...>]

Hi , 
I am trying to run valgrind on dex2oat command which converts a dex file 
to oat file on android platform with armv8 arch. 

However I see the below unhandled instructions logs when running valgrind. 

disInstr(thumb): unhandled instruction: 0xDEFF 0x4EA9
disInstr(thumb): unhandled instruction: 0xDEFF 0x9309
disInstr(thumb): unhandled instruction: 0xDEFF 0x4699
disInstr(thumb): unhandled instruction: 0xDEFF 0xF8DF


But the program is not killed . Is there anyway to know if these errors 
are significant ? How to debug this ?


thanks
