First thanks all for reviewing !
Basically, what's happening is that it works good with non-packed structures.
Here is an example for packed structure (with unsigned signed short):
c
struct lol {
unsigned short a:3;
unsigned short b:2;
unsigned short c:6;
unsigned short d:2;
unsigned short e:6;
} __attribute__((packed));
int main(void)
{
struct lol lolo = {
.a = 2,
.b = 1,
.c = 13,
.d = 2,
.e = 9
};
__builtin_dump_struct(&lolo, &printf);
return 0;
}
Here is the output I get :
sh
unsigned short a : 2
unsigned short b : 1
unsigned short c : 13
unsigned short d : 2
unsigned short e : 1
The last `unsigned short` is incorrect.
If I switch this to signed integers, I get :
sh
unsigned short a : 0
unsigned short b : 0
unsigned short c : 0
unsigned short d : 0
unsigned short e : 0
All the fields are zeroed. I absolutely do not understand what is happening...
Thanks for trying to help guys !
