looks like it is the __display function that is non synthesizable

Thanks - this is new behavior as __display was simply ignored in hardware as of Yosys 0.29+11. I've pushed a fix for this particular example (enclosing __display in pre-processor directives as it should have been). I'll look into a simpler approach where non synthesizable directives are simply ignored when targeting hardware.
