================
Comment at: clang/lib/AST/Interp/Interp.h:530-535
if (S.checkingForUndefinedBehavior()) {
SmallString<32> Trunc;
APResult.trunc(Result.bitWidth()).toString(Trunc, 10);
auto Loc = E->getExprLoc();
- S.report(Loc, diag::warn_integer_constant_overflow) << Trunc << Type;
+ S.report(Loc, diag::warn_integer_constant_overflow)
+ << Trunc << Type << E->getSourceRange();
