similar to: [LLVMdev] Adding PDB support to lib\DebugInfo

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.

>The pdb reading code relies *very heavily* on Windows APIs can you make shure not to have any windows api stuff in the pdb-reader interface so its easy to - if someone wants to - implement an windows-api independent version (support reading under linux etc.) because the pdb format needs to be analysed anyway for writing pdb information on compile/link (in the future) Am 29.01.2015 um 19:20

Hi Zach (or anyone else who may have a clue), I'm currently investigating making use of LLVM for PDB parsing for with a view to supporting partial PDBs as produced by /DEBUG:FASTLINK as the VS DIA SDK hasn't been updated to handle them. I know this is probably low on your priority list but since /DEBUG:FASTLINK is now the implied default for VS2017 I figure it's a good time to take a

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

Hello, Is anyone working on implementing DebugInfo/PDB that doesn't depend on DIA? What would it take to have minimal implementation that would allow to take a PDB file and look up symbols using llvm-symbolizer on a non-Windows (e.g. Linux or MacOS) platform?

Is making PDB files for corresponding IR supported in LLVM latest version? After some searching I see llvm-pdbdump, but I want to annotate the IR with debug information so that when I write bitcode it has pdb information. I've heard of CodeView, but it seems to be only for line information. I want variable values also. I would be ok to use DWARF if Visual Studio could understand it using

Hi Mike, > I'll check into that again. I ran across llvm-pdbdump earlier but couldn't get it to build on a vanilla 3.8 install (CMake is convinced I don't have the DIA SDK and I haven't found a way to change its mind). I have experienced something similar with the DIA SDK. Most of the time, it is a path problem: https://support.microsoft.com/en-us/kb/3035999

Hi, I would like to extend DebugInfo library for the purpose of using it in AddressSanitizer/ThreadSanitizer run-time libraries. Current interface is: class DILineInfo { const char *FileName; uint32_t Line; uint32_t Column; ... }; class DIContext { ... virtual DILineInfo getLineInfoForAddress(uint64_t address) = 0; }; First, I would like to get function name associated with the
