xref: /llvm-project/flang/test/Lower/optional-value-caller.f90 (revision 12ba74e181bd6641b532e271f3bfabf53066b1c0) 
1! Test lowering of OPTIONAL VALUE dummy argument on caller side.
2! RUN: bbc -emit-fir -hlfir=false %s -o - | FileCheck %s
3
4! A copy must be made if the actual is a variable (and no copy-out), but care
5! has to be take if the actual argument may be absent at runtime: the copy
6! must be conditional. When the allocation is dynamic, the temp allocation and
7! deallocation are also conditionals.
