Hi LLVM developers, As PR35281 mentioned: $ llvm-objcopy -O binary llvm-cortex-m7.elf llvm-cortex-m7.bin llvm-objcopy: 'llvm-cortex-m7.elf': The file was not recognized as a valid object file. if (ELFObjectFile<ELF64LE> *o = dyn_cast<ELFObjectFile<ELF64LE>>(&Binary)) https://github.com/llvm-mirror/llvm/blob/master/tools/llvm-objcopy/llvm-objcopy.cpp#L200

If you call lld::coff::link twice, the second time gives this backtrace: msvcp140d.dll!00007ffc35830806() Unknown > zig.exe!std::_Debug_pointer<lld::coff::Chunk * __ptr64 const>(lld::coff::Chunk * const * _Ptr, const wchar_t * _File, unsigned int _Line) Line 926 C++ zig.exe!std::_Debug_range2<lld::coff::Chunk * __ptr64 const * __ptr64>(lld::coff::Chunk * const *

Hi everyone, I’m currently playing with the clang driver and I encounter a strange bug. It occurs when I used the getSize function from the SymbolRef class. On iOS, the number returned is not always correct (some function have the right size). Sadly, This is my code (at the end of the main function into driver.cpp) : #### ErrorOr<OwningBinary<Binary>> BinaryOrErr =

I encountered a segfault when using lld to cross-compile for Windows (+MinGW) from Linux. The problem happens with objects built by gcc. The problem is that ObjFile::CreateRegular considers a PendingComdat to be valid (and later causes an illegal pointer dereference). The following patch fixes the crash: diff --git a/COFF/InputFiles.cpp b/COFF/InputFiles.cpp index 9e2345b0a..f47d612df 100644

Can you upload a reproducer? You can create it using the /linkrepro flag.

Hi Paul, How can i make this call to intrinsic from the c++ code ? I'm not working with the IR language, but directly in C++ with IRBuilder::CreateAlloca. My goal is that one : - Generate machine code with an instance of the class 'IRBuilder' - Emit 'ObjFile' class instance with MCJIT - Create a DwarfContext instance directly from the emitted ObjFile object

"IR" often refers to the general concept/semantics, not only the textual format in .ll files (there are 3 main forms - bitcode, textual IR, and the in-memory representation (llvm::Module, etc - constructed using IRBuilder)). A great place to start is to look at what Clang does to produce debug info - it uses IRBuilder, for instance. So you could look at how Clang uses the IRBuilder when

Hi, all: I want to check small files' property(such as date, path, and so on) frequently. The files are stored in netwrok driver and their sizes vary from 2KB to 5KB. I found that Windows 2K outperform Linux/Samba very much after I campared the bench results. I am very confused about it and who can explain it? The computers' configurations are as follows: 1.

Ah, crap, there's a gdb/jit.[ch] but I don't know how to get cvs diff to include them. 'cvs add' wants write access

Binding the alloca to the debug-info metadata is not automatic. You need to emit an intrinsic function call to llvm.dbg.declare to bind the two together. If you are simply trying to emit DWARF for your program, the rest of the processing should already be in place for that. If you are trying to do something else, you would need to describe that so we understand what you need. --paulr From:

You wouldn't normally expect to access a constant string via the GOT. It looks like LLVM has decided to put the symbols in an odd section, so it'd be a good idea to make sure

Hi, First, considering I'm using an IRBuilder and a DIBuilder to build my program, how can I automatically bind the CreateAlloca with my named local variable inside the DIBuilder ? Is it automatic with the Twine name of CreateAlloca ? And/Or should I use DIBuilder::createAutoVariable and how ? Then, I'm wondering how to locate back my local variable in memory (register or stack) once i
