This PR fixes two crashes in ExtractAPI that occur when decls are requested via libclang: - A null-dereference would sometimes happen in `DeclarationFragmentsBuilder::getFragmentsForClassTemplateSpecialization` when the template being processed was loaded indirectly via a typedef, with parameters filled in. The first commit loads the template parameter locations ahead of time to perform a null check before dereferencing. - An assertion (or another null-dereference) was happening in `CXXRecordDecl::bases` when processing a forward-declaration (i.e. a record without a definition). The second commit guards the use of `bases` in `ExtractAPIVisitorBase::getBases` by first checking that the decl in question has a complete definition. The added test `extract-api-cursor-cpp` adds tests for these two scenarios to protect against the crash in the future. Fixes rdar://140592475, fixes rdar://123430367
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.
