==30670== valgrind: Unrecognised instruction at address 0x2468cd6.
==30670== Your program just tried to execute an instruction that Valgrind
==30670== did not recognise.  There are two possible reasons for this.
==30670== 1. Your program has a bug and erroneously jumped to a non-code
==30670==    location.  If you are running Memcheck and you just saw a
==30670==    warning about a bad jump, it's probably your program's fault.
==30670== 2. The instruction is legitimate but Valgrind doesn't handle it,
==30670==    i.e. it's Valgrind's fault.  If you think this is the case or
==30670==    you are not sure, please let us know and we'll try to fix it.
==30670== Either way, Valgrind will now raise a SIGILL signal which will
==30670== probably kill your program.

Reproducible: Always

Steps to Reproduce:
1.use instruction rdtscp get tsc register

Actual Results:  
valgrind report the error that can not recognize the instruction


Expected Results:  
rdtscp is recognised. and the program can excecute
