NEG
BINARY APX_F x86_64
NEG is an instruction of the x86_64 architecture (x86 / x86-64 (covers 16/32/64-bit modes)), category BINARY. This page lists its 16 encoding forms, distinguished by opcode bytes: F6, F7.
Each form below links to its full decode: the operand roles and where each one is encoded in the instruction, the flag and register effects, and any micro-op sequence authored for it.
