--- Comment #4 from David Brown <david at westcontrol dot com> --- (In reply to Richard Biener from comment #1) > If you compile with debug info enabled the info should be already there, > just nothing looks at this (and mismatches) at link time. Perhaps I should file this as an enhancement request for binutils? If there is enough information already generated by gcc, then only the linker part needs to be implemented. (It could also be checked by an external program, but that would be a lot more inconvenient for the user.) Will the binutils folk be familiar with the debug information and its layout, or is there a document I can point them to? I assume this kind of information will be stable and documented, because gdb will need it. (I can read through the material for the details, but a rough pointer to get me started would help.)
