We don't currently apply any relocations (that I know of) for debug info in LLDB. > On Jun 2, 2014, at 12:35 PM, Keno Fischer <kfischer at college.harvard.edu> wrote: > > I think I'm getting closer.

I didn't get to work on this more last week, but I'll look at incorporating that suggestion. The other question of course is how to do this in LLDB. Right, now what I'm doing is going through and adjusting the load address of every leaf in the section tree. That basically works and gets me backtraces with the correct function names and the ability to set breakpoints at functions in

I'm using llvm-2.5 on OS X 10.5 and having a problem getting debug info from my compiler into a resulting executable. My code flow is: LLVM API -> Assembly file .s -> gcc to .dylib I'm using DIFactory to generate the debug info, and my usage seems to match what clang's CGDebugInfo would do. In my resulting assembly file, I see the DWARF sections with apparently valid

Hi Daniel, attached is a patch that pushes most of the object file specific parsing out of AsmParser and down into MachOAsmParser. This was done as a cleanup for the ELF work. I know that you're not happy with this approach, particularly the fact that as we add more object file formats and assembler dialects, it's going to cause a class explosion. But I was hoping that we could use this

Nothing in the llvm language reference indicates the behavior of a global with the 'internal' linkage attribute

Ok, I managed to compile the Ogg and Vorbis libs. Then, after modifying the file audio_out.c as follows: original: #include <dlfcn.h> modified: #include <win32/include/dlfcn.h> I was able to (finally!) compile libao. Then I tried to compile the module vorbis-tools, but uninvited problems came to my party. [...] > /usr/bin/ld: multiple definitions of symbol _getopt >

Hi Folks, I have a question regarding LLD support for ld64 mach-o linker synthesised symbols. I did a quick search of the LLD source and I can not find support for them so before I start trying to use lld I thought I would ask. I have found a couple of cases where they are essential. i.e. where there is no other way to get the required information, such as getting the address of the mach-o
