/* Below comes the architecture-specific code. For each architecture, we have
|
|
* the syscall declarations and the _start code definition. This is the only
|
|
* global part. On all architectures the kernel puts everything in the stack
|
|
* before jumping to _start just above us, without any return address (_start
|
|
* is not a function but an entry pint). So at the stack pointer we find argc.
|
|
* Then argv[] begins, and ends at the first NULL. Then we have envp which
|
|
* starts and ends with a NULL as well. So envp=argv+argc+1.
