Hi, I never got any response to this. Anyone care to comment?

Is this still being considered? Has anyone come up with an idea for a solution that does not include extending CTF? I understand that CTF doesn't support looking into the ELF binary, but perhaps there is a way around this. First, I'd like to explain what I wish to have, so that maybe a different solution could be suggested - In all, migration from an existing log-to-file system for existing projects may push the entire formatted string as the trace entry. We'd like to avoid storing the entire format string multiple times, as this is wasteful, of course, and we'd like the viewer to be in charge of performing the formatting. I was wondering whether we could use CTF enums. The CTF specification for enums doesn't say that the textual representation of the value has to be a valid identifier. In fact, the example includes a quoted string. An instrumentation tool could generate code that writes an enum description into the metadata, where each value corresponds to a different format string.
