For each architecture, we have 7271661c1SWilly Tarreau * the syscall declarations and the _start code definition. This is the only 8271661c1SWilly Tarreau * global part. On all architectures the kernel puts everything in the stack 9271661c1SWilly Tarreau * before jumping to _start just above us, without any return address (_start 10659ee30fSThomas Weißschuh * is not a function but an entry point). So at the stack pointer we find argc. 11271661c1SWilly Tarreau * Then argv[] begins, and ends at the first NULL. Then we have envp which 12271661c1SWilly Tarreau * starts and ends with a NULL as well. So envp=argv+argc+1. 13271661c1SWilly Tarreau */ 14271661c1SWilly Tarreau 15271661c1SWilly Tarreau #ifndef _NOLIBC_ARCH_H 16271661c1SWilly Tarreau #define _NOLIBC_ARCH_H 17271661c1SWilly Tarreau 18271661c1SWilly Tarreau #if defined(__x86_64__) 19271661c1SWilly Tarreau #include "arch-x86_64.h" 20271661c1SWilly Tarreau #elif defined(__i386__) || defined(__i486__) || defined(__i586__) || defined(__i686__) 21271661c1SWilly Tarreau #include "arch-i386.h" 22271661c1SWilly Tarreau #elif defined(__ARM_EABI__) 23271661c1SWilly Tarreau #include "arch-arm.h" 24271661c1SWilly Tarreau #elif defined(__aarch64__) 25271661c1SWilly Tarreau #include "arch-aarch64.h" 26*aa68a5a8SThomas Weißschuh #elif defined(__mips__) 27271661c1SWilly Tarreau #include "arch-mips.h" 280cb0675eSZhangjin Wu #elif defined(__powerpc__) 290cb0675eSZhangjin Wu #include "arch-powerpc.h" 30271661c1SWilly Tarreau #elif defined(__riscv) 31271661c1SWilly Tarreau #include "arch-riscv.h" 3218a5a09dSSven Schnelle #elif defined(__s390x__) 3318a5a09dSSven Schnelle #include "arch-s390.h" 3473f12c6dSFeiyang Chen #elif defined(__loongarch__) 3573f12c6dSFeiyang Chen #include "arch-loongarch.h" 3648946c5aSThomas Weißschuh #else 3748946c5aSThomas Weißschuh #error Unsupported Architecture 38271661c1SWilly Tarreau #endif 39271661c1SWilly Tarreau 40271661c1SWilly Tarreau #endif /* _NOLIBC_ARCH_H */ 41
