hj were only dicks on the mips it seems, but it's easy to add it to 8c.

t.c:

#include <u.h>
#pragma hjdicks dick
struct a {
	ulong x;
	long y;
	short z;
	};
#pragma hjdicks off
static int xxx = sizeof(struct a);
static struct a xx[2];
static int xxsize = sizeof(xx);

8c -S t.c

	DATA	xxx<>+0(SB)/4,$10
	DATA	xxsize<>+0(SB)/4,$20
	GLOBL	xxsize<>+0(SB),$4
	GLOBL	xx<>+0(SB),$20
	GLOBL	xxx<>+0(SB),$4

perhaps i should add "xen" as a synonym for "dick"
"on" will work too, if you'd like to be less rude.

also,
#pragma hjdicks xN
for some integer N sets the padding/rounding to N
