/* Linux-only by intention as Apple does not conform the the ARM Linux
|
|
system call conventions. Here, Apple would use x16 where this code
|
|
uses x8 and a value of 1 where this code uses 93.
|
|
|
|
Both platforms are handled correctly if you use the libcrt.
|
|
|
|
Also note that the return from main is limited to 8 bits. Thus, the
|
|
value used here (3510) will not yield that value, but 182 instead.
