Thanks. Note that there are still a few references to this MDNode scattered throughout the code-base, so if it's no longer being generated, there may be some bugs lurking there.

Thanks Eric. I know some of the references are in the code used for backward compatibility. - Devang On Feb 13, 2012, at 9:21 AM, Eric Christopher <echristo at apple.com> wrote: > Thanks.

Eric, Devang, FYI exactly the same applies for llvm.dbg.gv - it's also still listed in the docs and in various places throughout the code, although no longer generated.

So, I just sync'd to LLVM tip and added the call to DIBuilder::finalize(). But even with that change I am getting an error when I try to run llc: Assertion failed: (TheCU && "Unable to find compile unit!"), function endFunction, file /Users/talin/Projects/llvm/lib/CodeGen/AsmPrinter/DwarfDebug.cpp, line 1306.

Well, I am much happier now that I understand about dsymutil, and can actually step through my program in gdb. However, there are still some issues that are puzzling me. 1) First off, the debugger appears to stop at odd points. The IR for my main function looks correct to me: define i32 @"main(tart.core.Array[tart.core.String])->int"(%"tart.core.Array[tart.core.String]"*

I hate to be a nag, but after several days of working on this I am still utterly stumped. Let me recap the situation as it currently stands: I'm trying to write code that generates DWARF debugging information for my compiler using DIFactory and friends. Unfortunately the information I am generating appears to be invalid, but I can't figure out the cause. Based on the advice in the

Hi Talin, I mentioned it because the error message you are getting is identical (IIRC) to the error message being produced by llvm-gcc before this patch went in. Ciao, Duncan.

Yup. Now, the debug info nodes do not refer to compile unit. - Devang On Sep 5, 2011, at 2:23 AM, Duncan Sands wrote: > Hi Talin, I mentioned it because the error message you are getting is > identical (IIRC) to the error message being produced by llvm-gcc before > this patch went in. > > Ciao, Duncan. > > On 05/09/11 11:21, Talin wrote: >> On Sun, Sep 4, 2011 at

Hi All, Is there any documentation on how to use DIFactory to generate basic debug info? It seems similar enough to IRBuilder but working with objects (rather than pointers) and that's raising some issues. Also, am I supposed to run the ModuleDebugInfoPrinterPass manually, or it gets printed automatically when I WriteBitcodeToFile? -- cheers, --renato http://systemcall.org/ Reclaim
