I encountered a segfault when using lld to cross-compile for Windows (+MinGW) from Linux. The problem happens with objects built by gcc. The problem is that ObjFile::CreateRegular considers a PendingComdat to be valid (and later causes an illegal pointer dereference).

Hi Paul, How can i make this call to intrinsic from the c++ code ? I'm not working with the IR language, but directly in C++ with IRBuilder::CreateAlloca. My goal is that one : - Generate machine code with an instance of the class 'IRBuilder' - Emit 'ObjFile' class instance with MCJIT - Create a DwarfContext instance directly from the emitted ObjFile object (DwarfContextInMemory) (on JitEventListener::NotifyObjectEmitted) - Use this DwarfContext to step into my home made runtime debugger. Now I can perform step over/into/out in my debugger using t...

...for the summer. One dumb way to approach it would be to push the ELF creation to the GDB side of the interface, and create the ELF there. That would clean up the interface and make it much nicer. But once you've done that, then it's probably just as much work to figure out the in memory objfile data structures and modify those directly. This was just the path that yielded results most quickly. >> I know this code is sketchy and preliminary, but it's useful for us, >> and I have plans to improve it: >> http://wiki.llvm.org/HowTo:_Tell_GDB_about_JITted_code > >...

Binding the alloca to the debug-info metadata is not automatic. You need to emit an intrinsic function call to llvm.dbg.declare to bind the two together. If you are simply trying to emit DWARF for your program, the rest of the processing should already be in place for that. If you are trying to do something else, you would need to describe that so we understand what you need. --paulr From:

You wouldn't normally expect to access a constant string via the GOT. It looks like LLVM has decided to put the symbols in an odd section, so it'd be a good idea to make sure

Hi, First, considering I'm using an IRBuilder and a DIBuilder to build my program, how can I automatically bind the CreateAlloca with my named local variable inside the DIBuilder ? Is it automatic with the Twine name of CreateAlloca ? And/Or should I use DIBuilder::createAutoVariable and how ? Then, I'm wondering how to locate back my local variable in memory (register or stack) once i

Have you considered how this might be made to work for embedded targets where remote debugging is required? deep
