[ixp1200] compiler error "__mul_32 not found"

Hi, I got this compilation error in SDK 2.0 : (0): error : Function __mul_32 not found I use hash_48() in my micro C code. The parameters of hash_48 are sram xfer registers. And I declared and used other sram xfer registers too. Is the error because of running out of sram xfer registers ?
