KMOVB
KMASK APX_F_KOPB x86_64
KMOVB is an instruction of the x86_64 architecture (x86 / x86-64 (covers 16/32/64-bit modes)), category KMASK. This page lists its 10 encoding forms, distinguished by opcode bytes: 90, 91, 92, 93.
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.
