...arget doesn't support 64 bit arithmetic, so I'd like to supply definitions for adde/addc. The problem is I can't seem to figure out the magic. Here's an example of what I need to generate: # two i64s in r5/r6 and r7/r8 # result in r1/r2, carry in r3 # adde add r2, r6, r8 cmpltu r3, r2, r6 # compute carry # addc add r1, r5, r7 add r1, zero, r3 Is this possible given the current code generation stuff? Is there another approach that I should consider? -Rich
