Hi Avi, Attached is the patch to implement the push imm8 instruction opcode 0x6a.
Please apply or comment. And regarding the patches in the dos format, I tried sending patches to my yahoo/gmail account and I don't see them in the DOS format. It's strange it is reaching you in the DOS format. I don't know a way to avoid it right now. Please let me know if there is any known trick or method to avoid this issue. -- Thanks & Regards, Nitin Open Source Technology Center, Intel Corporation ----------------------------------------------------------------- The mind is like a parachute; it works much better when it's open
