5.5.3 Bitwise operations

and       w1 w2 – w        core       “and”

or       w1 w2 – w        core       “or”

xor       w1 w2 – w        core       “x-or”

invert       w1 – w2        core       “invert”

lshift       u1 n – u2        core       “l-shift”

rshift       u1 n – u2        core       “r-shift”

Logical shift right by n bits.

2*       n1 – n2        core       “two-star”

Shift left by 1; also works on unsigned numbers

d2*       d1 – d2        double       “d-two-star”

Shift left by 1; also works on unsigned numbers

2/       n1 – n2        core       “two-slash”

Arithmetic shift right by 1. For signed numbers this is a floored division by 2 (note that / not necessarily floors).

d2/       d1 – d2        double       “d-two-slash”

Arithmetic shift right by 1. For signed numbers this is a floored division by 2.
