Here are some issues that I am unclear about. What would be great is if the answers could be incorporated into the comments and documentation for DIFactory and DebugInfo.h: 1) What types of DIScope are valid arguments for DebugLoc::get()? The method takes an MDNode* argument, so looking at the function signature is no help. For example, DIFile is a subtype of DIScope, however looking at

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

Here is a patch that does just that.

BTW, the reason I stopped responding to this thread is not because I solved the problem, but because I simply gave up and decided to work on other things for a while since I was making no progress. Having finished those other things (the stack crawler, for one), I'm hoping that time and a fresh start will yield better results. Unfortunately after about a day spent reviewing old llvm-dev

Sometime about two months ago, something changed in LLVM that broke my frontend's ability to generate debug info. This was around the time that the requirement to call DIBuilder::finalize() was added (and yes, I am calling it.) Specifically, what I am seeing is an assertion failure in llc because it can't find the compile unit for a subroutine. I took a look at the code in DIBuilder.cpp,

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
