I guess both could work. I had seen the TARGET_INIT_LIB but, when I had tried playing with it, I got a segmentation fault in the emit_unop_insn function (for some reason, pat = GEN_FCN (icode) (temp, op0) was returning NULL). I guessed that either I had another problem in my MD file that was posing a problem or that I didn't define everything needed for the libcall system. This solution worked relatively straight away and is open enough to allow me to change the implementation later down the road. When things stabilize, I might go back and move the real function calls back to the libcall machinery. >> mult tmp1, a, b >> mult tmp2, c, d >> >> mov output1, tmp1 >> mov output2, tmp2 >> call bar Ok then I don't foresee a problem with the way I do it. Thanks again all of you, Jc
