[flang] Improve runtime SAME_TYPE_AS() (#135670)

The present implementation of the intrinsic function SAME_TYPE_AS()
yields false positive .TRUE. results for distinct derived types that
happen to have the same name.

Replace with an implementation that can now depend on derived type
information records being the same type if and only if they are at the
same location, or are PDT instantiations of the same uninstantiated
derived type. And ensure that the derived type information includes
references from instantiated PDTs to their original types. (The derived
type information format supports these references already, but they were
not being set, perhaps because the current faulty SAME_TYPE_AS
implementation didn't need them, and nothing else does.)

Fixes https://github.com/llvm/llvm-project/issues/135580.

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

Welcome to the LLVM project!

This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.

The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.

C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.

Other components include: the libc++ C++ standard library, the LLD linker, and more.

Getting the Source Code and Building LLVM

Consult the Getting Started with LLVM page for information on building and running LLVM.

For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.

Getting in touch
