The TBAA generation gives conservative TBAA metadata when handling an access of a record type with a descriptor member, since the access may be a regular data access OR another descriptor. Array members were being incorrectly identified as non-descriptor-members, and were giving incorrect TBAA metadata which led to bugs showing up in the optimizer when LLVM encountered mismatching TBAA. `fir::isRecordWithDescriptorMember` now unwraps sequence types before checking for descriptor members.
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.
