ELFFile::handleSectionWithNoSymbols() returns false for SHT_NOTE. This means that ELFFile::createAtoms() never creates an atom for .note sections. It seems like even if I use something like SDataSection, then I will still need to modify ELFFIle::handleSectionWithNoSymbols(). What is the best way to do this? Should I make the function virtual and override it in AMDGPUELFFile.cpp? In ELFDefinedAtom...

Hi, I'm working on an AMDGPU target for lld, and I'm trying to link a single .o file with a .note section, but the .note section is missing from the resulting a.out file. How can I control which sections get copied over to the executable? Is there a target hook to implement? Thanks, Tom

Looks like it is also not working on x86_64, using clang/lld I am seeing a segmentation fault: Dump of assembler code for function _Z4funcj: 0x0000000000400590 <+0>: push %rbp 0x0000000000400591 <+1>: push %rbx 0x0000000000400592 <+2>: push %rax 0x0000000000400593 <+3>: mov %edi,%ebp 0x0000000000400595 <+5>: pop %rdx 0x0000000000400596
