It's more like, this is the only thing you can do effectively as long as you have an unbounded value in the attribute. And the way the max_attr_length calculation works now, the only bounded values are selections of constants via if-then-else / cond. > Maybe if I just avoid incrementing the length in ADJUST_INSN_LENGTH when > it is MAX_INT, then the error won't occur. I suppose so, but you'd still have a ridiculous size estimate. And having one INT_MAX length instruction plus a delay slot insn can still push you over the INT_MAX edge.
