Hello, Thanks to those that attended the IPA/LTO BoF at GNU Cauldron over the weekend and gave us feedback on teaching GCC to optimize for layout locality in the callgraph I’d like to follow-up on the previous work in the area that Honza mentioned to see if we can reuse some of it or follow its best practices. Could you give us some pointers on the previous attempts? Also, I think richi suggested having a second WPA phase that does the layout separately from the partitioning. Is that something we decided was a good idea?
Thanks again for the great discussion! Kyrill
