+! When compiling for an OpenMP target device at -O0, a scalar-to-array
+! broadcast assignment inside a target region must still be inlined to
+! avoid emitting a _FortranAAssign runtime call (which internally uses
+! malloc/free) into GPU device code.

Even in this directory for OpenMP testing, most test use `-emit-hlfir`. Unless you need to check something in FIR, please favor emitting HLFIR
