Something like a .c file with two lines:

#include <stddef.h>
size_t siz = sizeof(whatever);

compile it using -S, and check the assembler output, e.g.:

        .file   "sizetest.c"
        .globl  siz
        .data
        .align 4
        .type   siz, @object
        .size   siz, 4
siz:
        .long   8		<--- there's your info :)
