I just updated from the most recent svn ToT. I'm now getting the following compilation errors. Looks like DIIContext.h needs some includes. Does anyone else see this error also? Am I missing something? In file included from DIContext.cpp:10: /extra/xguo/workspace/llvm/include/llvm/DebugInfo/DIContext.h:27: error: 'uint32_t' does not name a type

That relocation handling is only done for the llvm-dwarfdump binary. MCJIT handles relocations a bit different. I think you just need to go ahead and allow the MCJIT relocation handling machinery to work on non-alloc sections and it should go ahead and handle these just fine, unless you're using the existing stuff in lib/DebugInfo to print out information or something? If this isn't what

I'm working on adding source-based profiling support for MCJIT and in the process of implementing this, I came across a test case where an object is being generated that wants to have relocations applied to the .debug_line section. I see in the DebugInfo code that it currently only supports relocations applied to either the .debug_info or the .debug_info.dwo section. Can anyone give me an

Actually, MCJIT doesn't perform relocations on debug sections. I'm not sure that would matter anyway. The place where I'm handling the debug information is outside MCJIT and the MCJIT relocation code isn't really accessible at that point. Right now, when MCJIT emits an object image, it broadcasts an event to any registered listeners indicating that an object was emitted, passing

See my earlier response to Adrian. But I'll rehash the point here, which is that basically in the short term, I think it makes the most sense to keep them separate. In the future, if / when we decide to provide a unified interface (e.g libDebugInfo as you suggest), there will be additional machinery required to wrap the two interfaces, so we could move the DIContext class at that time. Does

For llvm-dwarfdump we need to handle relocations inside the debug info sections in order to successfully dump the dwarf info including strings. Nick sent out a partial patch that did this not too long ago and I've taken it and gone in a bit of a different direction, but kept the same basic architecture. In place of applying the relocations to the data we've read from disk I'm keeping

We already have a PDB implementation of DIContext in lib/DebugInfo that uses PDBs. The

Hi, I've built the llvm-dwarfdump tool from the 3.3 branch and ran it on simple binary compiled with dwarf4 debug information. The tool seem to read the file correctly including dwarf information (DIContext::getDWARFContext returns a valid context), but when trying to access line information, all I get is "<invalid>" string for the file name and 0's for line and column

I've been working on adding pdb reading support to llvm. This started as a tool for dumping info from a pdb (similar to llvm-dwarfdump), which has been checked in and currently has limited support for dumping pdb. There's still more to be done on the pdb dumping tool, but at this point -- to reduce duplicated effort -- I think it makes the most sense to start moving some of this logic

Hi Folks, Looking into some other issues, I came across a couple of oddities with regard to debug info for global variables (PR39900 <https://bugs.llvm.org/show_bug.cgi?id=39900> and PR39899 <https://bugs.llvm.org/show_bug.cgi?id=39899>). But a broader question I was wondering if it was anyone's radar (it's not something I'll be pushing on myself in the near future, but
