Bug ID: 32144
Summary: [modules/c++14] constexpr function does not return a
constexpr value
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: Modules
Assignee: unassignedclangb...@nondot.org
Reporter: gonzalob...@gmail.com
CC: dgre...@apple.com, llvm-bugs@lists.llvm.org
When enabling modules in the following situation
template <typename T>
static constexpr const auto var = std::numeric_limits<T>::max();
template <typename T, T val = var<T>>
using foo = std::integral_constant<T, val>;
foo<int> val;
I get an "error: non-type template argument is not a constant expression",
pointing that the "initializer of 'var<int>' is not a constant expression".
When disabling modules, everything compiles just fine.
