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.
