...%x ; <float> [#uses=1] store float %neg, float addrspace(11)* %result ret void } However, when I attempt to run it through my backend which can handle binary math ops correctly I keep asserting on the following item. Cannot yet select: 017B8010: i32 = fneg 017B7E78 What I cannot figure out is why it is attempting to pattern match on an i32 when there are no i32's in my test program. I've tried a custom lowering function that lowers it to dst = sub 0, src0 and forcing it to f32, but it complains that result and the op value types are incorrect....

What sorts of changes have you made to the SPARC backend? Have you tried looking at the output of "llc -view-dag-combine1-dags" and "llc -view-legalize-dags" to see where exactly this nod...
