jnsquireNow that I've got the DSPs being used to implement the MUL instructions in VexRiscv, there are still 4 DSPs free. It seems like it should be possible to use the remainder to implement addition/subtraction in the ALU as well, which should save a few more LUTs. Do you think this is worth trying to get Yosys to infer? Is it possible to control where17:49
jnsquireinferences happen? I haven't counted, but it seems likely there are more than 4 32-bit additions/subtractions in the generated verilog.17:49

xobsjnsquire: inferences are done by adding -dsp to the synth_ice40 command, which causes it to do an inference pass. You can't decide what gets inferred, though. It just guesses.22:34
