This new option will allow to output function information in the same format as addr2line from binutils emits: ... 0xABCDEF01 T function_name_is_here ... This feature is useful to profile the code when it is run in JIT by external tools like valgrind and google-perftools. For example, google-perftools runs addr2line on executable and uses the resulting file to resolve memory addresse...

Hi, all When compiling a program with -g -O0, and if we have a PC, then with addr2line, we can get the line number of the instruction. My quesions are: what is the result of Phi node instruction, can we get the similar results ? -- Best Regards! Eric Lew -------------- next part -------------- An HTML attachment was scrubbed...

The following two files correct problems with the ComboBox implementation. You will also need my typemap.i.patch file (forthcoming) in order for the void * typemap to work properly (I think).

Hi Ian, I am trying to add supporting dumping 32-bit guest on arm32 to see what happened in my dom0 kernel when booting. It seems gvirt_to_maddr() is not workable under arm32. But why has it been implemented both in include/asm-arm/arm{32,64}/page.h? Thanks.

...;t see the issue with v0.4.0, but do with v0.5.0. The sphinx version doesn't seem to make any difference. I could downgrade my module version (and have temporarily done so). However, that leads to another issue: the links to llvm-symbolizer's page in https://llvm.org/docs/CommandGuide/llvm-addr2line.html are broken when building with 0.4.0. This can be fixed by changing the markdown doc to explicitly specify ".html" in the link, but this precise change is what breaks 0.5.0 (which otherwise produces working links in the llvm-addr2line doc). I think we should update the build bots vers...

Hi All, I want to change debug information of an llvm instruction so that the modified debug info is subsequently passed to executable binary. So if I use "addr2line" utility on the binary, it will return my modified debug information. I've tried to change by using the following code snippet: MDNode *N = Inst->getMetadata("dbg"); DebugLoc Loc = DebugLoc::get(newLine, newCol, N); Inst->setDebugLoc(Loc); I read the DebugLo...

Debug information, even if it's a little off, would be extremely useful to have in the final binary. This build chain worked with a 2.6svn versi...

(resurrecting the thread, as much is discussed here already) Formulating Kostya's suggestion: What do you think of compiling LLVM sources into ASan/TSan runtime by just taking the library sources, providing custom compiler (target) flags *and* a flag "-Dllvm=__sanitizer_llvm"? Yeah, it's hacky and applicable to LLVM libs, but OTOH we don't plan to use smth else for now (in
