I'm not sure what you mean when you say that gcc doesn't support floating point. The normal gcc releases always support floating point. If the processor does not have any floating point instructions, then gcc generates calls to runtime library routines. Those runtime library routines are generally found in libgcc, and are often compiled from config/fp-bit.c or from config/soft-fp/* or from hand-written assembler code. The first two choices should work even for an unusual target. Ian
