手册中提到系统调用的编号的符号常量可以在头文件 sys/syscall.h 中找到。 Symbolic constants for system call numbers can be found in the header file <sys/syscall.h>. 我们可以通过 <sys/syscall.h> 这个文件查看系统调用编号,位置在 /usr/include/sys/syscall.h 文件。 6 寄存器在系统调用中的作用 寄存...
Syscalls numbers are // assigned using this ordering too. The lowest stub address will be the stub with the lowest // syscall number (0 in this case). We just need to iterate `stub_map` and iterate the syscall // number on every iteration. static inline void ExtractSyscallsNumbers() ...

instead of using defined value inlind_platform.h. Wasmtime and Rawposix also has their seperate definition file for syscall numbers. Besides, we should also change the syscall number to align with linux syscall number. So in summary, here are things we need to clean up for syscall numbers:...
