Here is the table from flang where this is used.

lib/Optimizer/Builder/IntrinsicCall.cpp
1375:    // llvm.lround behaves the same way as libm's lround.
1376:    {"nint", "llvm.lround.i64.f64", genIntF64FuncType<64>, genLibCall},
1377:    {"nint", "llvm.lround.i64.f32", genIntF32FuncType<64>, genLibCall},
1378:    {"nint", "llvm.lround.i32.f64", genIntF64FuncType<32>, genLibCall},
1379:    {"nint", "llvm.lround.i32.f32", genIntF32FuncType<32>, genLibCall},
