MULSI3_LIBCALL definition

["lorenzo ivaldi" <lord at atlas dot dibe dot unige dot it>]

Could someone tell me how to implement MULSI3_LIBCALL macro apart from the libgcc1.a?

I am writing a compiler for a microcontroller produced in my laboratory and I haven't found any documentation apart a brief note on the gccdocs that refer to the examples provided in the description of the m68k.

Our chip do not have a physical mul and i have adapted the booth algorithm. But now I must insert it in place of the mul.

The compiler's asm calls "__mulsi3" and i do not know how to insert the algorithm.

Thanks in advance for assistance.
