<pre>I am getting a compile error when I try to use llvm::DITypeRefArray::iterator
or llvm::TypedMDOperandIterator< llvm::DINode >. It only happens when compiling
with gcc, not clang. I tried with both llvm 4.0.1 and llvm 5.0.1
Test file: test.cpp
---
#include <llvm/IR/DebugInfoMetadata.h>
int main() {
llvm::DITypeRefArray v;
std::find(v.begin(), v.end(), llvm::DITypeRef());
return 0;
}
---
Command: g++-7 -std=c++11 -Ipath-to-llvm/include test.cpp
Error:

I'm not sure what the problem is.
Side note: defining std::iterator_traits< llvm::DITypeRefArray::iterator > and
iterator_traits< llvm::TypedMDOperandIterator< llvm::DINode > > myself fixes
the issue.</pre>
