示例1: Logical
BufferOffset Assembler::Logical(const Register& rd, const Register& rn,
const Operand& operand, LogicalOp op)
{
VIXL_ASSERT(rd.size() == rn.size());
if (operand.IsImmediate()) {
int64_t immediate = operand.immediate();
unsigned reg_size = rd.size();
VIXL_ASSERT(immediate != 0);
VIXL_ASSERT(immediate != -1);
VIXL_ASSERT(rd.Is64Bits() || is_uint32(immediate));
// If the operation is NOT, invert the operation and immediate.
if ((op & NOT) == NOT) {
op = static_cast<LogicalOp>(op & ~NOT);
immediate = rd.Is64Bits() ? ~immediate : (~immediate & kWRegMask);
}
unsigned n, imm_s, imm_r;
if (IsImmLogical(immediate, reg_size, &n, &imm_s, &imm_r)) {
// Immediate can be encoded in the instruction.
return LogicalImmediate(rd, rn, n, imm_s, imm_r, op);
} else {
// This case is handled in the macro assembler.
