Venerable NOP instruction and more

Monday, January 29th, 2007

Does NOP instruction have “parameters”? Yes, it does (depends on CPU model). As I promised earlier I continue to update Asmpedia. Today I added ModRegRM table useful for both disassembling and assembling and NOP description together with WinDbg output:

ModRegRM byte (32/64-bit addressing) 

Note: REX prefix information will be added later

NOP instruction

I’ll keep you up with Asmpedia updates on weekly bases.
