+! nonlazybind and the RtLibUseGOT module flag are applied to the LLVM module
+! after FIR is translated, so -emit-hlfir and -emit-fir cannot observe them.
+! -fno-plt marks an external procedure nonlazybind and requests GOT for
+! compiler-rt. A procedure defined in this file is left unchanged. The
+! default, and -fplt after -fno-plt, do neither.

The `NOPLT-NOT` for the intrinsic has to come after the `attributes #[[ATTR]]`
line, not before it. `@ext_` uses the `nonlazybind` group first, so it is
printed as `#0` and the intrinsic's group follows it. In its current place the
check only scans the one line between the `sin` declaration and `attributes
#0`, so it never sees the intrinsic's group: adding `nonlazybind` to the
`llvm.sin.f32` attributes still passes. The other new checks do catch their
defects.
