I don't think the lang ref metadata grammar section (http://llvm.org/docs/LangRef.html#metadata) has been fully updated with how !dbg metadata is used in http://llvm.org/docs/SourceLevelDebugging.html. At least to me it is not clear. In my mind I translate the phrase "LLVM IR allows metadata to be attached to instructions " into a grammar depicted in SourceLevelDebugging.html. I was going to ask about this, but I'll let you instead. :-) Garrison On Feb 11, 2010, at 16:42, D...

Hi, I want to retrieve a function from a source line-number, is this something possible to achieve? I tried the following code snippet with LLVM-7 but it doesn't seem to workhttp://llvm.org/docs/SourceLevelDebugging.html#ccxx_frontend <http://llvm.org/docs/SourceLevelDebugging.html#ccxx_frontend:> Is there specific documentation I can refer to implement this?

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.getDire...

...uld suggest actually just invoking clang, since it knows how to call the system linker. > 2) Making system calls Call syscall()? I'm not completely sure what you're asking. > 3) Creating debug info I don't think we have any good examples for debug info... http://llvm.org/docs/SourceLevelDebugging.html might be helpful, though. In general, docs are available at http://llvm.org/docs/SourceLevelDebugging.html . -Eli

Is anyone maintaining this page? http://llvm.org/docs/SourceLevelDebugging.html#composite-type-descriptors DIBuilder::createSubroutineType seems to generate metadatas with a different format. Thanks!

Are there examples on doing the following? 1) Creating stand alone executables 2) Making system calls 3) Creating debug info Obviously clang does all this, but I was hoping for something less complex. -------------- next part -------------- An HTML attachment was scrubbed...

Hello, Could I get some debug info at the byte code level? I am writing a passer and if will be nice if I can know which line in the source an instruction (or value) corresponds to. I found a document online: http://llvm.org/docs/SourceLevelDebugging.html, but I can't find an example of doing it at the byte code level. Cheers, Zheng

Thanks for your help. I took a look at http://llvm.org/docs/SourceLevelDebugging.html and it seems like this doesn't give you much in the way of line number information. If you know what source line you are interested in then you can set a breakpoint, but suppose you want to know the line number in the source code for some arbitrary bytecode instruction. In my particular ca...

...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 http://llvm.org/docs/SourceLevelDebugging.html <http://llvm.org/docs/SourceLevelDebugging.html> However, looks like that the instruction " DILocation Loc(N);” is not valid anymore, Since the DILocation class is changed. Is that right? How can I extract debug info (line, filename, etc.) from an instruction? Thanks. Best Regard...

Hello I'm reading http://llvm.org/docs/SourceLevelDebugging.html and some things aren't clear. There are a couple of references made to %llvm.dbg.variable, which isn't defined anywhere. It it an intrinsic? A global? Could it be a relic from the old debug info docs (where it *is* defined?). The same goes for llvm.dbg.derivedtype and llvm.dbg.subrang...

Hi all, In LLVM documentation about source level debugging (http://www.llvm.org/releases/2.9/docs/SourceLevelDebugging.html) Subprogram descriptor is defined as: !2 = metadata !{ i32, ;; Tag = 46 + LLVMDebugVersion <http://www.llvm.org/releases/2.9/docs/SourceLevelDebugging.html#LLVMDebugVersion> ;; (DW_TAG_subprogram) i32, ;; Unused field. metadata, ;; Reference to context descr...

The Rust compiler defines all functions as returning void, with the first parameter being an outparam of the declared return type, ie. fn foo2() -> int { ret 5; } becomes define void @_ZN4foo217_5cb557d30658848cE(i64*, { i64, { %tydesc*, i1, {} } }*) uwtable { store i64 5, i64* %0 ret void } I'm working on generating debug information for Rust, and I'm currently stumped on how
