7 | * the syscall declarations and the _start code definition. This is the only |
8 | * global part. 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 point). 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. |
