Fortran has a limited form of dynamic scoping[https://tinyurl.com/2p8v2hw7] between "host procedures" and "internalprocedures". There are a number of implementations possible.Boxproc typed values abstract away the implementation details of when afunction pointer can be passed directly (as a raw address) and when afunction pointer has to account for the presence of a dynamic scope.When lowering Fortran syntax to FIR, all function pointers are emboxedas boxproc values.When creating LLVM IR, we must strip away the abstraction and producelow-level LLVM "assembly" code. This patch implements thattransformation as converting the boxproc values to either raw functionpointers or executable trampolines on the stack as needed. Thetrampoline then captures the dynamic scope context within an executablethunk that can be passed instead of the function's raw address.Some extra handling is required for Fortran functions that return acharacter value to deal with LEN values here.Some of the code in Bridge.cpp and ConvertExpr.cpp and be re-arranged tofaciliate the upstreaming effort.This patch is part of the upstreaming effort from fir-dev branch.Reviewed By: jeanPerier, PeteSteinfeldDifferential Revision: https://reviews.llvm.org/D122223Co-authored-by: mleair <leairmark@gmail.com>Co-authored-by: Jean Perier <jperier@nvidia.com>Co-authored-by: Eric Schweitz <eschweitz@nvidia.com>Co-authored-by: V Donaldson <vdonaldson@nvidia.com>Co-authored-by: Kiran Chandramohan <kiran.chandramohan@arm.com> List of files: /llvm-project-15.0.7/flang/test/Lower/allocatable-runtime.f90 Tue, 22 Mar 2022 14:40:32 +0000 Valentin Clement <clementval@gmail.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/flang/test/Lower/allocatable-runtime.f90#179ea355 [flang] Add tests for allocatable globalThis patch adds couple of tests for allocatableglobals and missing lowering for themThis patch is part of the upstreaming effort from fir-dev branch.Reviewed By: PeteSteinfeldDifferential Revision: https://reviews.llvm.org/D121473Co-authored-by: Jean Perier <jperier@nvidia.com>Co-authored-by: Eric Schweitz <eschweitz@nvidia.com> List of files: /llvm-project-15.0.7/flang/test/Lower/allocatable-runtime.f90 Fri, 11 Mar 2022 17:39:33 +0000 Valentin Clement <clementval@gmail.com>
