search for: auto_ptr

The upcoming C++1z (probably C++17) standard will not contain several things - most notably auto_ptr. Soon, libc++ will not be providing auto_ptr by default when building in C++1z mode. You'll be able to get it back with a "-D_LIBCPP_ENABLE_CXX17_REMOVED_AUTO_PTR" on your command line, or "#define _LIBCPP_ENABLE_CXX17_REMOVED_AUTO_PTR" before including any libc++ header fi...

...he following assertion from a program I've written: /home/vadve/criswell/src/llvm22/lib/VMCore/Value.cpp:57: virtual llvm::Value::~Value(): Assertion `use_empty() && "Uses remain when a value is destroyed!"' failed. This occurs when I free a Module (the program uses an auto_ptr() to the Module, and the auto_ptr() moves out of scope). It looks like the code that frees a BasicBlock frees all of its instructions in order without regards to the def-use chains. However, the Value class's destructor has the assertion that the Value has no uses. Is the assertion an err...

Hi, I am trying to load another bytecode file in one pass. I checked the opt.cpp, it uses following to load a bytecode file: ... LLVMContext &Context = getGlobalContext(); ... SMDiagnostic Err; // Load the input module... std::auto_ptr<Module> M; M.reset(ParseIRFile(InputFilename, Err, Context)); ... My question is in the runOnModule method where I want to load another bytecode file, what context should I use? Is getGlobalContext() still OK? Thanks, Guoliang

Here is the bulk of the sanitizing. My residual doubts center around the question whether we still do/want to support (un)compressed *byte*code in 2.0/2.1. I need a definitive word on this to proceed. My understanding is that bytecode is already gone, but there are still some functions/enums that really deal with *byte*code (instead of *bit*code). I did not touch those areas, so the attached
