Hi All,
In gcc, cmpxchg16b instruction is included as part of ISA CX16.
In binutils, same instruction is included as part of ISA SSE3 (Ref. opcodes/i386-opc.tbl) and there is no CX16 ISA
I could find lot of references for cmpxchg16b being part of CX16 ISA but not SSE3
Can somebody throw some light on this?
Regards,
Saravanan
