fortran: array descriptor: Move descriptor copy function [PR122521]
Fortran array descriptor copy function moved to a central location.
The copy_descriptor function, used for copying array descriptors in the Fortran front-end, has been moved from trans-stmt.cc to trans-descriptor.cc and renamed to gfc_copy_descriptor. This change consolidates descriptor handling logic into trans-descriptor.cc and updates the call site in trans_associate_var. This refactoring is part of addressing PR122521.
In Details
This commit relocates and renames the copy_descriptor function, part of the Fortran front-end's array descriptor handling, from trans-stmt.cc to trans-descriptor.cc. It is now named gfc_copy_descriptor, and its declaration is added to trans-descriptor.h. The caller trans_associate_var in trans-stmt.cc is updated accordingly. This move centralizes descriptor management functions within trans-descriptor.cc, aligning with the refactoring efforts for PR122521.
- array descriptor
- A data structure used by compiled Fortran code to represent an array. It typically holds information such as the array's base address, bounds, element size, and stride.
- trans-stmt.cc
- A source file within the GCC Fortran front-end likely containing code related to statement translation and processing, including constructs like
ASSOCIATE. - trans-descriptor.cc
- A source file within the GCC Fortran front-end that likely contains code related to the translation and manipulation of data descriptors, including array descriptors.
- ASSOCIATE
- A Fortran construct that allows temporary association of variables with other variables or expressions, often used for aliasing or simplifying access to complex data structures.
