Hi Folks, Looking into some other issues, I came across a couple of oddities with regard to debug info for global variables (PR39900 <https://bugs.llvm.org/show_bug.cgi?id=39900> and PR39899 <https://bugs.llvm.org/show_bug.cgi?id=39899>). But a broader question I was wondering if it was anyone's radar (it's not something I'll be pushing on myself in the near future, but

A couple weeks ago I sat down with David Blaikie to figure out what we could trim when importing debug metadata during function importing. I have a prototype that reduces the resulting .o sizes significantly with ThinLTO -g. However, I ran into some issues when cleaning up part of this in preparation for a patch. Since Mehdi indicated that he and Adrian were going to be looking at this as well

Hi all, I wanted to summarise some discussion on llvm-commits [0,1] as an RFC, as I felt it demanded wider circulation. Our support for references to absolute symbols is not very good. The symbol will be resolved accurately in non-PIC code, but suboptimally: the symbol reference cannot currently appear as the immediate operand of an instruction, and the code generator cannot make any assumptions
