Hi, For my project, I am using internal llvm class functions to print the filename and directory associated with an instruction from the debug information. With a recent checkout of llvm and clang (svn revision 129445), the following custom code (e.g. in a pass that prints directory info for all instructions) returns the filename iso. directory whenever Scope refers to a lexical block: if (const

That's because instructions have a location associated with them, not a compile unit. -eric On Thu, Oct 4, 2012 at 12:46 PM, George Baah <georgebaah at gmail.com> wrote: > I used DILocation instead of DICompileUnit and it works.

You should probably think of the DIFooBar constructors like reinterpret-casts, not "go find the thing I actually want" functions. If you hand DICompileUnit() a node that is not a compile-unit metadata node, it's not going to tell you that you goofed. If you _did_ have a CU metadata node, then DICompileUnit's getDirectory() would work just fine. But you don't. --paulr

Hmmm, but it has a getDirectory function. -G On Thu, Oct 4, 2012 at 3:50 PM, Eric Christopher <echristo at gmail.com> wrote: > That's because instructions have a location associated with them, not > a compile unit. > > -eric > > On Thu, Oct 4, 2012 at 12:46 PM, George Baah <georgebaah at gmail.com> wrote: > > I used DILocation instead of DICompileUnit and

Here is the code. I am running on llvm 3.1 on Lion (Mac 10.7.4) *string getFileDirectory*(*const* Instruction &I){ MDNode *MD = I.getMetadata("dbg"); DICompileUnit compileUnit(MD); return compileUnit.getDirectory().str(); } George On Wed, Oct 3, 2012 at 12:40 PM, Eric Christopher <echristo at gmail.com>wrote: > Without knowing the code that you've written

I used DILocation instead of DICompileUnit and it works. Hmmm, interesting. George On Thu, Oct 4, 2012 at 1:33 AM, George Baah <georgebaah at gmail.com> wrote: > Here is the code.

Yeah, It looks like I am doing exactly what's in Dwarf*.cpp files, yet I am getting blanks.

Hi all, I used to extract the debug information from an LLVM Instruction in the following way: if (MDNode *N = I->getMetadata("dbg")) { // Here I is an LLVM instruction DILocation Loc(N); // DILocation is in DebugInfo.h unsigned Line = Loc.getLineNumber(); StringRef File = Loc.getFilename(); StringRef Dir = Loc.getDirectory(); } As specified also at

Hi, I found the following at http://llvm.org/docs/SourceLevelDebugging.html#ccxx_frontend: if (MDNode *N = I->getMetadata("dbg")) { // Here I is an LLVM instruction DILocation Loc(N); // DILocation is in DebugInfo.h unsigned Line = Loc.getLineNumber(); StringRef File = Loc.getFilename(); StringRef Dir = Loc.getDirectory(); } Does this also

Hi Guys, How does one get the directory of the compilation unit in llvm? I am using DICompileUnit but for some reason I am getting blanks for the directory name. Here is my code ... MDNode *MD = I.getMetadata("dbg"); DICompileUnit compileUnit(MD); *return* compileUnit.getDirectory().str(); Thanks George -------------- next part -------------- An HTML attachment was scrubbed...

Without knowing the code that you've written and the IR that you're running on I'm not sure what I can do to help you. -eric On Wed, Oct 3, 2012 at 9:32 AM, George Baah <georgebaah at gmail.com> wrote: > Yeah, It looks like I am doing exactly what's in Dwarf*.cpp files, yet I am > getting blanks. > > George > > On Tue, Oct 2, 2012 at 2:10 PM, Eric

Hi I am not a good programmer but for my project i have to use llvm to generate CFG for c programs where i have a mapping from IR instruction in CFG to their respective c instruction. After surfing a in source of llvm i did the following change in printInstruction() function in llvm/lib/VMCore/AsmWriter.cpp file. .....void AssemblyWriter::printInstruction(const Instruction &I) { if

Dear LLVMers, I'm updating some code to use the new LLVM 2.7 API. One piece of this code uses the findStopPoint() function to find the source filename and line number information of an instruction. What is the best way to do this under LLVM 2.7 now that the stop point intrinsic has been removed? It appears that the debug information is attached as metadata, but what is the easiest way
