[CMake] Use PRIVATE in target_link_libraries for executables We currently use target_link_libraries without an explicit scope specifier (INTERFACE, PRIVATE or PUBLIC) when linking executables. Dependencies added in this way apply to both the target and its dependencies, i.e. they become part of the executable's link interface and are transitive. Transitive dependencies generally don't make sense for executables, since you wouldn't normally be linking against an executable. This also causes issues for generating install export files when using LLVM_DISTRIBUTION_COMPONENTS. For example, clang has a lot of LLVM library dependencies, which are currently added as interface dependencies. If clang is in the distribution components but the LLVM libraries it depends on aren't (which is a perfectly legitimate use case if the LLVM libraries are being built static and there are therefore no run-time dependencies on them), CMake will complain about the LLVM libraries not being in export set when attempting to generate the install export file for clang. This is reasonable behavior on CMake's part, and the right thing is for LLVM's build system to explicitly use PRIVATE dependencies for executables. Unfortunately, CMake doesn't allow you to mix and match the keyword and non-keyword target_link_libraries signatures for a single target; i.e., if a single call to target_link_libraries for a particular target uses one of the INTERFACE, PRIVATE, or PUBLIC keywords, all other calls must also be updated to use those keywords. This means we must do this change in a single shot. I also fully expect to have missed some instances; I tested by enabling all the projects in the monorepo (except dragonegg), and configuring both with and without shared libraries, on both Darwin and Linux, but I'm planning to rely on the buildbots for other configurations (since it should be pretty easy to fix those). Even after this change, we still have a lot of target_link_libraries calls that don't specify a scope keyword, mostly for shared libraries. I'm thinking about addressing those in a follow-up, but that's a separate change IMO. Differential Revision: https://reviews.llvm.org/D40823 llvm-svn: 319840

[clang-repl] Land initial infrastructure for incremental parsing In http://lists.llvm.org/pipermail/llvm-dev/2020-July/143257.html we have mentioned our plans to make some of the incremental compilation facilities available in llvm mainline. This patch proposes a minimal version of a repl, clang-repl, which enables interpreter-like interaction for C++. For instance: ./bin/clang-repl clang-repl> int i = 42; clang-repl> extern "C" int printf(const char*,...); clang-repl> auto r1 = printf("i=%d\n", i); i=42 clang-repl> quit The patch allows very limited functionality, for example, it crashes on invalid C++. The design of the proposed patch follows closely the design of cling. The idea is to gather feedback and gradually evolve both clang-repl and cling to what the community agrees upon. The IncrementalParser class is responsible for driving the clang parser and codegen and allows the compiler infrastructure to process more than one input. Every input adds to the “ever-growing” translation unit. That model is enabled by an IncrementalAction which prevents teardown when HandleTranslationUnit. The IncrementalExecutor class hides some of the underlying implementation details of the concrete JIT infrastructure. It exposes the minimal set of functionality required by our incremental compiler/interpreter. The Transaction class keeps track of the AST and the LLVM IR for each incremental input. That tracking information will be later used to implement error recovery. The Interpreter class orchestrates the IncrementalParser and the IncrementalExecutor to model interpreter-like behavior. It provides the public API which can be used (in future) when using the interpreter library. Differential revision: https://reviews.llvm.org/D96033
