llvm-project.git/lldb/test/Shell/ObjectFile/MachO/section-overflow-binary.test, branch main Unnamed repository; edit this file 'description' to name the repository. Enable LLDB to load large dSYM files. (#164471) 2025-10-30T21:08:44+00:00 Greg Clayton gclayton@fb.com 2025-10-30T21:08:44+00:00 3475b3f97b3060880c31c8b8a440f47f9d654e49 llvm-dsymutil can produce mach-o files where some sections in __DWARF exceed the 4GB barrier and subsequent sections in the dSYM will be inaccessible because the mach-o section_64 structure only has a 32 bit file offset. This patch enables LLDB to load a large dSYM file by figuring out when this happens and properly adjusting the file offset of the LLDB sections. I was unable to add a test as obj2yaml and yaml2obj are broken for mach-o files and they can't convert a yaml file back into a valid mach-o object file. Any suggestions for adding a test would be appreciated.
