A Cray pointee reference must be done using the characteristics (bounds, type params) of the original pointee declaration, but using the actual address value of the associated Cray pointer. There might be multiple Cray pointees associated with the same Cray pointer. The proposed solution is to lower each Cray pointee into a POINTER variable with a descriptor. The descriptor is initialized at the point of declaration of the pointee, though its base_addr is set to null. Before each reference of the Cray pointee its descriptor's base_addr is updated to the current value of the Cray pointer. The update of the base_addr is done using PointerAssociateScalar runtime call, which just updates the base_addr of the descriptor. This is a temporary solution just to make Cray pointers work to the same extent they work with FIR lowering.
The LLVM Compiler Infrastructure
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.
