...entry and in fact points out of the section border. Please correct me if I miss something. I think we can fix that by the following way: 1. Do not try to merge SHF_MERGE sections if Config->Relocatable is true. 2. Do not group such sections together or group sections with the same SHF_STRINGS / sh_entsize parameters. 3. Keep SHF_STRINGS flag and sh_entsize value when writing the sections. In that case a linker will be able to merge/reduce such sections later when it links a relocatable object to get DSO or executable file.

You are right. LLD does not have this problem. Initially I bumped into the MIPS specific bug related to GP relative relocations calculation. I tried to make reproduction script as general as possible and mistakenly make it too general. So now with your help I realized that the problem solely affects MIPS.

Hello, all experts. When I use pid provider, my Dscript with -F option output the codepath with flowindent as you know, e.g. -> main -> f1 -> f2 however I realized that the exec file I used at that time was stripped. Does anyone know the reason why I could see the function names? Thanks in advance. -- This message posted from opensolaris.org

The atoms have a merge type of mergeByConent (which seems to be currently missing from DefinedAtom.h). The core linking part of lld knows to coalesce atoms that have the same size and content if their merge type is mergeByConent. I will go ahead and add the type when I have support for th...

This idea popped up in the review thread for https://reviews.llvm.org/D25627 . Problem: Currently, LLD creates special sections that are not just concatenations of input sections but need link-time data generation, such as .got, .plt, interp, .mips.options, etc., as output sections. We have OutputSectionBase subclasses (e.g. GotSection, PltSection, etc.) to create data. Even though this scheme
