Update to work with LLVM 2.7. Removed use of dyn_cast, llvm no compiles without exceptions and rtti by default. We do need exceptions for the libconfig stuff, but rtti isn't necessary (anymore). Debug info needs to be rewritten, as in LLVM 2.7 the format has completely changed. To have something to look at while rewriting, the old code has been wrapped inside #ifndef DISABLE_DEBUG_INFO , this means that you have to define this to compile at the moment. Updated tango 0.99.9 patch to include updated EH runtime code, which is needed for LLVM 2.7 as well.

#ifndef LDC_GEN_LINKAGE_H
#define LDC_GEN_LINKAGE_H

#include "gen/llvm.h"

// Make it easier to test new linkage types

#  define TYPEINFO_LINKAGE_TYPE           LLGlobalValue::LinkOnceODRLinkage
// The One-Definition-Rule shouldn't matter for debug info, right?
#  define DEBUGINFO_LINKONCE_LINKAGE_TYPE LLGlobalValue::LinkOnceAnyLinkage

extern LLGlobalValue::LinkageTypes templateLinkage;

#endif
