Hi all, I wrote code that compiled with llvm 3.0 And when I compile i llvm-3.0/llvm/include/llvm/Support/Casting.h:50:12: error: type 'unsigned long' cannot be used prior to '::' because it has no members return To::classof(&Val);                 ^~~ Do you know what's wrong ?

I see a bunch of definitions scattered throughout LLVM, and I could not find good documentation on them. I don't understand why they exist when LLVM is being compiled with RTTI enabled. It seems to me that: isa<T>(x) is a substitute for (dynamic_cast<T>(x) != NULL) and there are some other similar casting tools defined in Casting.h. Why should I use these instead of C++'s

Moving to LLVM dev to discuss the possibility of extending the cast infrastructure to handle this.

Well, line 364 wasn't actually what was holding me up, so it's a bad example, but the problem's still relevant. Using cast<...>(iter), dyn_cast<...>(iter), or isa<...>(iter) results in the error messages mentioned below. ________________________________ When compiling LoadValueNumbering.cpp, I get the following errors:

Been having a bit of a problem with dyn_cast: Suppose I have a class A that inherits from two base classes, both of which support dyn_cast. In order to use dyn_cast on A, I need to do a bunch of extra work: 1) Since dyn_cast uses reinterpret_cast rather than static_cast, the pointer value won't get adjusted by the cast operation, making the pointer invalid. I end up having to redefine

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

MetaSplit is an anlysis I just finished writing. It doesn't alter anything, all it does is build a set of "program instructions". For some reason even though if I run it with any other combination of passes I've found, anytime I run it with mem2reg I get a seg fault in dyn_cast! Here's output: Starting program: /mounts/zion/disks/0/localhome/pmeredit/llvm/tools/Debug/opt
