• %rax: return value• %rsp: stack pointer• %rdi: 1st argument• %rsi: 2nd argument• %rdx: 3rd argument• %rcx: 4th argument• %r8: 5th argument• %r9: 6th argument

To manage a variable-size stack frame, x86-64 code uses register %rbp to serveas a frame pointer
frame pointer 什么情况下会使用?
-
convention, registers %rbx, %rbp, and %r12–%r15 are classified as callee-saved registers. When procedure P calls procedure Q, Q must preserve the valuesof these registers, ensuring that they have the same values when Q returns to P asthey did when Q was called
callee-saved register 有什么作用,应该如何理解?

As with themov instructions, the two operands cannot both be memory locations.
binary operation 的两个操作数可以是 memory location 吗?
-
This operand can be either a register ora memory location.
unary 的操作数可以是什么?
-
The destination operand must be a register.
load effective address 的 destination 需要是什么?

The ability of the leaq instruction to perform addition and limited forms ofmultiplication proves useful when compiling simple arithmetic expressions suchas this example.
leaq 在什么情况下有用?

local variables such as x are often kept in registers rather thanstored in memory locations. Register access is much faster than memory access.
local variables 通过会存在哪里,为什么?
-
One important feature is that memoryreferences in x86-64 are always given with quad word registers, such as %rax, evenif the operand is a byte, single word, or double word.
memory reference 属于那种 register 类型?
-
logicallybe named movzlq, but this instruction does not exist. Instead, this type of datamovement can be implemented using a movl instruction having a register as thedestination. This technique takes advantage of the property that an instructiongenerating a 4-byte value with a register as the destination will fill the upper 4bytes with zeros.
为什么在 movz 的指令中缺少 movzlq?

The old high-born hag, who called herself her protectress, and was her tyrant, had seen me, also; she hobbled, panting, up the terrace; a page, as ugly as herself, held up her train, and fanned her as she hurried along, and stopped my fair girl with a "How, now, my bold mistress? whither so fast? Back to your cage--hawks are abroad!"
HA! I think this may be high register because he does not like the lady. She wouldn't let him and Bertha meet each other.

my objective in The Order of Things1 had been toanalyse verbal clusters as discursive layers which fall outside thefamiliar categories of a book, a work, or an author. But while Iconsidered 'natural history', the 'analysis of wealth', and 'politicaleconomy' in general terms, I neglected a similar analysis of theauthor and his works; it is perhaps due to this omission that Iemployed the names of authors throughout this book in a naiveand often crude fashion. I spoke of Buffon, Cuvier, Ricardo, andothers as well, but failed to realize that I had allowed their namesto function ambiguously. This
Goal of "Order of things" was to analyse verbal clusters as discursive layers that are not books but other types of discourse: natural history, wealth, political economy and so on.
