I am trying to generate a undefined instruction by using pseudo-instruction mentioned in http://www.keil.com/support/man/docs/armasm/armasm_dom1361289918908.htm
My inline assembly code like below:
__asm volatile ("UND 0xe7f000f0")
However I got this error:
Error: #3061: unrecognized instruction opcode
To me seems like UND is not recognized as no matter how I play with the 0xe7f000f0 value part , always show this error, would like to know if anyone tried the UND instruction and what might be wrong in my inline assembly?
