SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***
Request For Enhancement (RFE): At run-time initialization, then memcheck should give a Note about cpu instructions on the current executing hardware, that VEX does not support.  Such as: "Note: this version of valgrind does not support these instructions of this CPU: aes bmi1 bmi2".  Such a Note would enhance usability by giving early warning of Unrecognized Instruction.  Getting a friendly warning at the beginning, instead of "vex amd64->IR: unhandled instruction bytes: 0x..." and several lines of spew, is much more pleasant.
