Tīmeklis2024. gada 13. jūn. · Today I’m going to write up one small (and yet still remarkably complicated) fragment of x86_64’s instruction semantics: memory addressing. Specifically, I’m going to write up the different ways in which x86_64 allows the user to address memory via just one instruction: mov. I won’t attempt to cover other … Tīmeklis2024. gada 13. aug. · rax是64位寄存器的称呼，但是这个寄存器是可以拆分的。例如我们操作eax，就是在对rax的低32位进行操作。同样以此类推，ax表示rax的低16位，ah表示rax低16位中的高8位，al表示rax低16位中的低8位。除了rip之外，其余的寄存器都可以做类似的拆分。 5.2 rbx ck weather

RIP的特殊性以及PIC（位置无关代码）因为RIP寄存器存放着当前指令的地址，所以有它的特殊性。比如上面的%rip + displacement，其中displacement存放的如果是_bss这个symbol与该指令的“距离值”，那么不管这段代码所在的section装载到哪个位置，都可以通过这个计算，访问到_bss实际装载的位置。 Tīmeklis2024. gada 25. jūn. · 기준 문법: Intel syntax 기준 어셈블러: nasm op-code (명령어) mov mov reg, 값 : reg를 값으로 덮어씌움 mov reg, reg : 첫번째 reg를 두번째 reg 값으로 덮어씌움, 단 두 레지스터의 크기가 같아야 한다. pop 스택으로부터 값을 뽑아냄. pop rax라면 스택 맨 위의 값(rsp가 가리키는 값)을 뽑아다 rax에 집어넣음. push ...

TīmeklisIt seems like it would be helpful for making a JMP to a subroutine and back. So the 64 bits from RIP would be put in RAX prior to the JMP to the subroutine. Then RAX would be incremented by 1 within the subroutine. Then the subroutine would JMP to the address stored in RAX. When I try this, NASM gives me "error: symbol `RIP' undefined". Tīmeklis2024. gada 16. apr. · In the example shown, the hexpairs are disassembled using 64bit assembly, and you probably want to change it to a 32bit assembly. Just tell radare …

TīmeklisIn a PIE, the instruction might be written movq g(%rip), %rax, which works out without having to know the starting address of the program's code in memory at compile time (instead, %rip contains a number some known number of bytes apart from the starting point, so any address relative to %rip is also relative to the starting point).

Tīmeklis因为加法会用到 %rax，而下面 add 函数的返回值也会使用 %rax。由于 %rax 是 Caller Save 寄存器，在调用 add 子函数之前，程序应该先保存 %rax 的值。 add 函数使用了 8 个参数，这是为了观察当函数参数多于6个时程序的行为，前6个参数会保存到寄存器中，多于6个的 ... ckw construction ltdTīmeklis组装:有人能解释一下这行 leaq 指令的作用吗？. 我正在运行一些汇编代码，但我无法弄清楚一行代码的作用。. 代码是: 我知道 lea 基本上是一种 mov 指令，但它只移动地址。. 所以我们将某物的地址移动到 %rdx (使 %rdx “指向”堆栈上的某些东西)。. 我知道什么 … down and back wagon trainsTīmeklis2011. gada 4. sept. · I am trying to assemble a file that contains code which directly references the RIP register (note, I did not write this code, I am trying to use existing assembly).
