Re: [Valgrind-users] [Bug] There is the bug about valgrind decode armv8 thumb instruction

    When the machine code is 0x4503,   the op is cmp,   but this is the T2 format , N bit(7-bit) is 0 ,  so   the thumb instrunction cmp-hi  is unhandled. And the decode action is failure .     The 0x4503 machine code is generate by clang4.0\5.0\6.0, the machine  cpu
