On all architectures the kernel puts everything in the stack 9 * before jumping to _start just above us, without any return address (_start 10 * is not a function but an entry pint). So at the stack pointer we find argc. 11 * Then argv[] begins, and ends at the first NULL. Then we have envp which 12 * starts and ends with a NULL as well. So envp=argv+argc+1. 13 */ 14 15#ifndef _NOLIBC_ARCH_H 16#define _NOLIBC_ARCH_H 17 18#if defined(__x86_64__) 19#include "arch-x86_64.h" 20#elif defined(__i386__) || defined(__i486__) || defined(__i586__) || defined(__i686__) 21#include "arch-i386.h" 22#elif defined(__ARM_EABI__) 23#include "arch-arm.h" 24#elif defined(__aarch64__) 25#include "arch-aarch64.h" 26#elif defined(__mips__) && defined(_ABIO32) 27#include "arch-mips.h" 28#elif defined(__riscv) 29#include "arch-riscv.h" 30#endif 31 32#endif /* _NOLIBC_ARCH_H */
