Detailed Description

SetRuntimeCallAttributesPass looks for fir.call operations that are calling into Fortran runtime, and tries to set different attributes on them to enable more optimizations in LLVM backend (granted that they are preserved all the way to LLVM IR). This pass is currently only attaching fir.call wide atttributes, such as ones corresponding to llvm.memory, nosync, nocallbac, etc. It is not designed to attach attributes to the arguments and the results of a call.
