On all architectures the kernel puts everything in the stack 9*271661c1SWilly Tarreau * before jumping to _start just above us, without any return address (_start 10*271661c1SWilly Tarreau * is not a function but an entry pint). So at the stack pointer we find argc. 11*271661c1SWilly Tarreau * Then argv[] begins, and ends at the first NULL. Then we have envp which 12*271661c1SWilly Tarreau * starts and ends with a NULL as well. So envp=argv+argc+1. 13*271661c1SWilly Tarreau */ 14*271661c1SWilly Tarreau 15*271661c1SWilly Tarreau #ifndef _NOLIBC_ARCH_H 16*271661c1SWilly Tarreau #define _NOLIBC_ARCH_H 17*271661c1SWilly Tarreau 18*271661c1SWilly Tarreau #if defined(__x86_64__) 19*271661c1SWilly Tarreau #include "arch-x86_64.h" 20*271661c1SWilly Tarreau #elif defined(__i386__) || defined(__i486__) || defined(__i586__) || defined(__i686__) 21*271661c1SWilly Tarreau #include "arch-i386.h" 22*271661c1SWilly Tarreau #elif defined(__ARM_EABI__) 23*271661c1SWilly Tarreau #include "arch-arm.h" 24*271661c1SWilly Tarreau #elif defined(__aarch64__) 25*271661c1SWilly Tarreau #include "arch-aarch64.h" 26*271661c1SWilly Tarreau #elif defined(__mips__) && defined(_ABIO32) 27*271661c1SWilly Tarreau #include "arch-mips.h" 28*271661c1SWilly Tarreau #elif defined(__riscv) 29*271661c1SWilly Tarreau #include "arch-riscv.h" 30*271661c1SWilly Tarreau #endif 31*271661c1SWilly Tarreau 32*271661c1SWilly Tarreau #endif /* _NOLIBC_ARCH_H */ 33
