Is there a compiler option or pragma that allows me to see "padding" in c structure?

typedef struct st
{
char a;
int b;
} mytype; Basically, say I have above defined struct then I wish to known how compiler pads it.

list file does not seem to provide the needed details.

--diag_warning=1301
--diag_warning=2530

I tried above options, it shows warning when ever the compiler pads but the issue is i still do
not get how many bytes and where the padding is applied in the structure.

is there a easy way to get those two details ?
