Hi, I have a question about the requirements for GDB port to a new target: is support for Dwarf Call Frame Information required for acceptance, or is prologue analysis sufficient? Thanks --Don
Hi Don,Can you provide more context? I can interpret your question in two ways:
- Your producer does not produce CFI, so you would be forced to always use prologue analysis for unwinding. In that case, I guess it's fine, GDB should do its best with the information at its disposal. - Your producer produces CFI but GDB for your architecture won't use it. In that case, I would ask why don't you use it. It's generally more reliable and less hair-pulling than prologue analysis.
