I've been debugging a segfault issue with the elfreader and I would like to point out something that I have noticed. ELF.h declares an inline function, getElfArchType (MemoryBuffer *Object). When this function is called from ObjectFile::createELFObjectFile the pointer to Object was getting corrupted. The only thing that distinguished this pointer was that it was declared as a unique_ptr. The flow from when it was created to getElfArchType is pretty direct. The segfault only happens only at optimization level -O0. The segfa...

Hello, The ObjectFile class (in Object/ObjectFile.h) presents a format-independent interface for object files. In addition, for COFF and MachO, some internal format details are exposed in special headers. For example, Object/COFF.h exposes coff_file_header and coff_symbol. Object/MachOFormat.h exposes headers, "se...

I have a few questions about the new ORC JIT. I saw Lang Hames (hi!) excellent talk at the llvm-dev meeting a few weeks ago. The ORC JIT is undergoing some API changes and I'd like/need to take advantage of them. (1) How do I take ownership of the ObjectFile once the ORC JIT has created it? I'd like to take ownership of object files generated by the ORC JIT so that I can save them to disk and in later sessions reload them. (2) How would I pass an ObjectFile saved in question#1 back to ORC so that it will relocate it and generate function point...

...s. I want to do some progress in fuzzing before we finish it (especially if we decide to make a significant intrusive changes), you may scroll down for my plan. The code in lib/Object calls report_fatal_error() far too often, both when we're (a) just constructing the specific implementation of ObjectFile, and (b) when we access its contents and find out the file is broken and can't be parsed properly. We should just go and fix (a): ObjectFile factory methods return ErrorOr<std::unique_ptr<ObjectFile>>, and we should propagate the error appropriately. (b) is harder. The current ap...

...rary archives. It would be very useful if there was a map of the dependencies between the files (e.g. if you link X.o you need Y.a and Z.o). Trying to figure out the link lines by trial and error is a bit frustrating. To assist myself with understanding this, I've started to write a document (ObjectFiles.html, attached) that will (eventually) explain all this. Right now its pretty much just a list of the various files produced by building LLVM and a cursory statement of what the file contains. The most significant need in the document is for a section on the dependencies between the various fil...
