I am targeting GCC 4.1.1 to a custom RISC processor; which has some vector instructions (32 bit vectors). It can perform two 16 bit/ or four 8 bit additions, subtractions, multiplications & shift operations simultaneously.
I would like to use the Auto-Vectorizing capability to generate these instructions. Is there an existing backend that I could look at for something similar? Any help will be greatly appreciated. SD
