| 导语 ABI(Application Binary Interface)描述了应用程序和OS之间的底层接口。其中,通过查阅调用约定(Calling Convention),我们可以了解到子过程调用是如何传递参数及返回值的,其中的细节包括有参数或返回值传递的位置(寄存器/栈)和使用细节、传参的顺序、调用前后的清理工作等。 目前,主流移动设备CPU主要采用ARM处理器。
ARM64 Calling Convention规定了整数型返回值放在x0寄存器里。由于我们这里是1 byte的char 类型数据,所以通过sturb将数据对用的内存里。 2.11 条件语句 从最简单的if-else看起,有如下代码: #include<stdio.h>voidmain(){intz,a=2,b=1;if(a>b){z=a;}else{z=b;}} 对应的汇编代码如下: _main: ; @ma...

On the other hand, the ARM64 calling convention considers portions of all 32 NEON vector registers as scratch. This difference was not reconciled for ARM64EC code generation, so unfortunately the C/C++ compiler has to be conservative and preserve those registers in the entry thunk - even ...

ARM64 SMP多核启动(下)—PSCI-上面说了pin-table的多核启动方式,看似很繁琐,实际上并不复杂,无外乎主处理器唤醒从处理器到指定地址上去执行指令
consisting of ARM64EC machine code. Intrinsics have an entry thunk of their own. All other functions share an entry thunk with all functions that have a matching calling convention, parameters, and return type. The content of the thunk depends on the calling convention of the C/C++ function....
It is a hybrid x64/ARM64 calling convention and binary layout. So it is built using the same tools as native ARM64, except you add one additional -arm64EC command line argument: cl hello.c <== this is pure native ARM64 target cl -arm64EC hello.c <== this generates a hybrid ARM...
