There are many processors I don't know. What I'm interested in is

In the GCC source code:
grep INT_TYPE_SIZE gcc/config/*/*.h
There are also a number of out-of-tree gcc ports.
Similar information on them would be interesting too.
Pretty hard to come by, though. Many out-of-tree ports are
out-of-tree for a reason.
Usually, a regular compiler user just needs to know the size of int on the particular
architecture he's working on, not on every processor/OS existing on the wild. So, the
simpler is just to run a program like :
#include <stdio.h>
int main()
{
printf("sizeof int = %d\n", sizeof(int));
}
If someone needs, for some valid reason, that the integer variables be 16-bit wide, the
good practice to write clean, portable and maintainable code is to use "int16_t" integer
type instead of just "int".
