Bug ID: 37633
Summary: overflow builtins are not constexpr
Product: clang
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: C++14
Assignee: unassignedclangb...@nondot.org
Reporter: j...@mcfarlane.name
CC: llvm-bugs@lists.llvm.org
It would be beneficial if overflow builtins [1] could be used in constant
expressions. This would bring Clang in line with GCC 7.x [2].
