Certainly true for the plain text output, but this bit of the abicc report seems clear enough:




Great to see it caught that issue.

> For example, in version 17.1 instability struct ResultRelInfo got changed with a new data member, in execnodes.h file as per this blog[1], but the abidiff report gives "14 functions with some indirect sub-type change" and all those 14 were affected due to the same cause, i.e. ResultRelInfo struct - thus making a need to parse the output in a better format, I believe.

Presumably, then, you could write a tool to parse it and produce conclusions similar to those from the abicc report, yes?

Best,
