Hello,
I'm starting to play with LLVM today and I've trouble compiling it. I'm working under Windows Vista, with the gcc from Cygwin:
gcc (GCC) 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)
Is LLVM supposed to work with this version of GCC (probably using the -mno-cygwin option to get a Mingw-like behavior)?
The LLVM source tree is from the current SVN trunk.
Compilation fails at SelectionDAG.cpp:
llvm[3]: Compiling SelectionDAG.cpp for Debug build
SelectionDAG.cpp: In function `void AddNodeIDNode(llvm::FoldingSetNodeID&, llvm::SDNode*)':
SelectionDAG.cpp:344: error: call of overloaded `AddInteger(llvm::MVT::ValueType)' is ambiguous

/home/afrisch/llvm/llvm/include/llvm/ADT/FoldingSet.h:152: note: void llvm::FoldingSetImpl::NodeID::AddInteger(uint64_t)

Before that, I get some warnings:
