Hi, I did some experiments to convert cross-reference table to resolution files. Patches are attached and still crude.
The initial idea is to have as little as possible change in GNU LD. It turns out that cross reference table doesn't always print out definition at the first line. So some change is needed there. In addition, offset within archive file is also useful. Nonetheless, such changes may break existing cref users. Maybe it is better to dump to a different file. Collect2 is modified to convert the enhanced cross-reference table to a full resolution file and used it in subsequent linking steps. Maybe I can move this part into LD. I am just not sure if it is easy to have similar functions in BFD as those in libelf. And it will be a much bigger change on GNU LD then. I have tried with small examples, and our mixed C/assembly applications. It works well with -flto/-fwhole-program. Any opinion on this approach? Thanks, Bingfeng
