LOG: [flang] Implement passing of assumed-type actual arguments. (#83851)
Passing `TYPE(*)`actual to `TYPE(*)` dummy was left TODO. Implement it.
The difference with other actual arguments is that `TYPE(*)` are not
represented as Fortran::evaluate::Expr<T>, so inquiries on
evaluate::Expr<T> must be updated to use evaluate::ActualArgument or
also handle semantics::Symbol case (except in portion of the code where
`TYPE(*)` is impossible, where asserts are added).
Added:
flang/test/HLFIR/assumed-type-actual-args.f90
Modified:
flang/lib/Lower/ConvertCall.cpp
