or the immediate operand IMUL forms:

anyreg32=anyreg/mem32 * SXimm8/imm32

ie: IMUL eax,ebx,-09

(unfortunately no unsigned MUL in this forms)

Maybe you should use an other assembler which allows
you to define the alias MUL for this IMUL instruction.
Or directly code it in HEX, if you use uppercase letters,
the CPU does an unsigned multiply (try it and you will
see it works):

00000000: 69 c3 fffffff7 muls.l #-9,r3,r0
00000006: 69 C3 FFFFFFF7 mulu.l #4294967287,r3,r0
