That means that there are 4 bits now for DstMask. "In the good old days cpus would have only one register that was able to fully participate in arithmetic operations, typically called A for Accumulator. The x86 retains this tradition by having special, shorter encodings for the A register (like the cmp opcode), and even some instructions that only operate on A (like mul). SrcAcc and DstAcc would accommodate these instructions by decoding A into the corresponding 'struct operand'." -- Avi Kivity Signed-off-by: Guillaume Thouvenin Signed-off-by: Avi Kivity --- Reading git-diff-tree failed
