[LLVMdev] Clang API parsing of the destructor
I am using the clang API (version 3.1 - trunk 153913) to compile some very simple code as follows class MyClass { ~MyClass() ; }; MyClass::~MyClass() { } int main() { return 0; } My problem is that I get the error message: test.cpp:20:10: error: destructor cannot have a return type MyClass::~MyClass() If someone can point me to the right direction that would be great. It compiles fine if

[LLVMdev] libclang JIT frontend
Hi, I'm not sure if this is a libclang, llvm::cl or clang-interpreter issue so I'll try posting here for a response. I am using libclang as a frontend to the LLVM JIT (3.3 release). I started from the clang-interpreter example and have everything working (given a C/C++ source file I can have it JIT'd to memory and executed) for a single run. When I try to compile a second source

Manuel, After the discussion at last night, I have agreed that GetTemporaryDirectory() on Win32 would do bad thing, thank you. dir = GetTemporaryDirectory(); dir.eraseFromDisk(erase_contents = true); dir = GetTemporaryDirectory(); /* It doesn't create anything on Win32 due to caching */ I suppose Manuel wants GetTemporaryDirectory() to keep semantics similar mkdtemp(3).

[LLVMdev] Unable to do even basic Clang tutorial
You will need to link to the LLVM/clang libraries. To get the correct flags, you can run: ./llvm-config --ldflags --libs and use the flags reported. On 7/10/2012 11:35 AM, NY Knicks Fan wrote: > OK.

[LLVMdev] FreeBSD's 11.0-CURRENT contrib/llvm/include/llvm/ADT/IntrusiveRefCntPtr.h's IntrusiveRefCntPtr and its use violates C++ privacy rules
When trying to build the 11.0-CURRENT clang 3.5 on powerpc64 I ran into a violation of C++ accessibility rules (for private) that stopped the compile. So not the usual defect category. (This was a bootstrapping procedure as powerpc/powerpc64 FreeBSD world’s clang has an odd status and getting from 3.4 under 10.1-STABLE to 3.5 on 11.0-CURRENT is not automatic.) Given the language rules and

This should be fixed in 5044196b412f. That helped a bit, but not yet fully. Looks like it might be still reachable memory, so leakcheck isn't that helpful. Oooh. I think I see.

[LLVMdev] Why is "typedef boost::shared_ptr<MyClass> MyClass_ptr" named "struct.boost::MyClass_ptr" by llvm-g++?
Hi, In the code below, MyNamespace::MyClass_ptr will be named "struct.boost::MyClass_ptr" by llvm-g++, and not "struct.MyNamespace::MyClass_ptr" as I expected. I observed this with the real boost::shared_ptr but used the code below (also attached as structnametest1.cc) on the demo page (http://llvm.org/demo/index.cgi) to reproduce the behavior. When I extended my test code

RTTI with smart pointers
Hi, I would like to use std::shared_ptr in my pass. However I'm facing a problem wrt RTTI. If I have a code like: std::shared_ptr<BaseClass> x(new DerivedClass()); ... std::shared_ptr<DerivedClass> p = std::dynamic_pointer_cast<DerivedClass>(x); It does not compile since the default RTTI infrastructure is not used by LLVM. Also, it's not clear to me if the
