<p class="MsoNormal"><span style="font-size:11.0pt">Hi<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Can you help me to understand if I’m doing anything wrong or the problem is with lld?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I need to use linker-script (below link) for linking freebsd kernel modules and pass -r to ld.lld (version 10) to make these modules relocatable.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Some of the modules that I build are very big and also have .group sections on rela.text.<mangledname> and .text.<mangledname>
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Per ELF specification these sections should be treated as one and either all merged or none. But I think lld is not respecting that spec and merges all .text.<mangledname> sections while leaving the .group
and .rela.text.<mangledname> sections in the output, which results in broken elf (when I try to load it into gdb, I get Bad Value error)<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Alternatively, when I link with ld.bfd, the .text.<manglenames> remain in the output and I’m able to load the object into gdb without error.<o:p></o:p></span></p>
