...at’s a good question, by default when emitting the object file I choose COFF but it embeds dwarf and not codeview in the end.. there probably is a way to do it or at least it must be implemented if not yet.. Lets imagine I manage to do that.. when you say there is nothing to do, I still must have a PDBFileBuilder to copy the codeview data inside the EXE PDB right ? I cannot insert them easily in the EXE PDB with another way ?

...rogram which does JIT compilation - get the start RVA of the .text section (which is always 0x1000 in my case) - Load the .DLL and use the ModuleAddress+RVA as a memory buffer in a custom DllMemMgr I give to MCJIT - On NotifyObjectEmitted replace the dll pdb by a custom one I build myself with your PDBFileBuilder - On finalizing memory, reload first the dll to trigger visual studio pdb reloading (not working don't know why yet), ensure it goes into the same virtual space, protect memory using VirtualProtect. - Place a breakpoint in my JIT file, it displays "loaded", execute JIT, it breaks .....

...em for me to have duplicated symbols. Concerning TypeIndices my plan if possible is not to generate a pdb for my jit and merge it, but instead directly extract debug info from a DwarfContext just after llvm::object::ObjectFile is emitted by the JIT engine and complete the EXE PDB I had rebuilt with PDBFileBuilder. Does it sounds a good bet to you ? If I succeed doing that I think that could be a good extension to the debugging possibilities of MCJit if not being an extension to pdbutil.

Hi Zachary ! If there a way to easily create a new PDBFileBuilder from an existing PDBFile or can/should I do the translation myself ? I would like to start from a builder filled with the EXE PDB data and then complete its DBI stream with the JIT module/symbols. Thanks !

Sure. Along the way I’m happy to answer any specific questions you might have too even if it’s for your downstream project On Wed, Jan 16, 2019 at 1:38 PM Vivien Millet <vivien.millet at gmail.com> wrote: > I would be up to improve pdbutil but I doubt I have enough knowledge or > time to provide the complete merge feature, it would still be a very > specific kind of merge as you
