Hi.
I wasn't aware there are now rules for what can and cannot go in DW_AT_producer.
DW_AT_producer has gone from being informational to having a formal
spec (in the sense that something will break if, for example, a
particular option is mentioned).
Is this spec written down somewhere? [At least guidelines for what
things may lead to breakage?]
