如果处理器的操作数寄存器是16位的,那么就称该处理器是16位处理器。
If the operand registers of a processor are 16 bits wide, the processor is said to be a 16-bit processor.
字的大小这一术语(也称字长)描述了操作数寄存器的大小,但它也可用来不那么严格地描述出入处理器的通道的大小。
Technically, the term work size(also called word length) describes the size of an operand register, but it is also used more loosely to describe the size of the pathway to and from the processor.
现在让我们看一下如何将个别寄存器作为操作数的约束指定。
Now let's take a look at how to specify individual registers as constraints for the operands.
specific intrinsic 的所有操作数都会映射为一个称为qword 的特殊类型,它实际上是一个opaque寄存器值类型。
All operands to specific intrinsics are cast to a special type called qword, which is essentially an opaque register value type.
所有实际的处理都发生在寄存器之间(或寄存器和立即寻址模式操作数之间)。
All of the actual processing takes place between registers (or between registers and immediate-mode operands).
它将第二个操作数内的寄存器与第三个操作数内的常量加在一起,并将结果存储在第一个操作数内指定的寄存器中。
It adds together the register in the second operand with the constant in the third operand, and stores the result in the register specified in the first operand.
大多数指令都遵循类似的格式,结果存储在第一个操作数内指定的寄存器中。
Most instructions follow a similar format, with the register that holds the result specified in the first operand.
它还规定在存储设备与一组32位矢量寄存器(Vector Register,VR)之间存取和储存的字节、半字、字和四字操作数。
It also provides for byte, halfword, word, and quadword operand fetches and stores between storage and a set of 32 Vector Registers (VRs).
第一个操作数是目标寄存器,第二个操作数是要加载的D -Form地址。
"The first operand is the destination register and the second is the D-Form address to load."
一种寄存器,可以存放某种操作的一个操作数,并且随后又用该操作的结果替换所存的操作数。
A register in which one operand of an operation can be stored and subsequently replaced by the result of that operation.
执行过程中的一个阶段所需的时间,在此期间,计算机从主存储器中取出指令或操作数,并将其存入控制器或运算器的寄存器中。
The part of execution in which an operand or instruction is read from main storage and written into a control unit or arithmetic unit register.
双%%前缀,指明这是一个寄存器名。单%指明操作数。 这帮组GCC辨别操作数和寄存器。
There are two %'s prefixed to the register name. This helps GCC to distinguish between the operands and registers. operands have a single % as prefix.
你可以使用不精确的指令和操作数并符合32位寄存器RA和RB。
You can use imprecise commands and operands and matching 32-bit registers ra and RB.
操作数可以是一个128位的XMM寄存器或内存地址。
The operand is either a 128-bit XMM register or a memory address.
当操作指定了“r”限制符,那么操作数将会被存储在通用寄存器内。
When operands are specified using this constraint, they get stored in General Purpose Registers(GPR).
当操作指定了“r”限制符,那么操作数将会被存储在通用寄存器内。
When operands are specified using this constraint, they get stored in General Purpose Registers(GPR).
