function(get_system_libs return_var)
Simplify linking to system libraries The LLVMSupport library implementation consolidates all dependencies on system libraries. Move the logic gathering system libraries out of 'cmake/modules/LLVM-Config.cmake' and into 'lib/Support/CMakeLists.txt'. Use the target_link_libraries() command there to tell CMake about the link dependencies of the LLVMSupport implementation. CMake will automatically propagate this to all targets that link LLVMSupport directly or indirectly. We still need to build knowledge of system library dependencies into 'llvm-config'. Store the list of libraries needed in a property on LLVMSupport and teach 'tools/llvm-config/CMakeLists.txt' to retrieve it from there. Drop all calls to 'link_system_libs' and 'get_system_libs' from our CMake code. Replace their implementations with a warning that explains the calls are no longer necessary. Also drop from 'LLVMConfig.cmake' the HAVE_* and related variables that were published there only to allow 'get_system_libs' to run outside our build process.

Fixed the build of Clang's unit tests on MinGW. Also removed some unnecesary conditionals and introduced a new convenience function. The problem was that the list of libraries for Clang's unit tests was <clang libraries> <system libraries> <llvm libraries>. As the llvm libraries references symbols defined on the system libraries, those were reported as undefined. llvm-svn: 128484

macro(llvm_config executable)
[cmake] rework LLVM_LINK_LLVM_DYLIB option handling Summary: This diff attempts to address the concerns raised in http://reviews.llvm.org/D12488. We introduce a new USE_SHARED option to llvm_config, which, if set, causes the target to be linked against libLLVM. add_llvm_utility now uniformly disables linking against libLLVM. These utilities are not intended for distribution, and this keeps the option handling more centralised. llvm-shlib is now processes before any other "tools" subdirectories, ensuring the libLLVM target is defined before its dependents. One main difference from what was requested: llvm_config does not prune LLVM_DYLIB_COMPONENTS from the components passed into explicit_llvm_config. This is because the "all" component does something special, adding additional libraries (namely libLTO). Adding the component libraries after libLLVM should not be a problem, as symbols will be resolved in libLLVM first. Finally, I'm not really happy with the DISABLE_LLVM_LINK_LLVM option, but I'm not sure of a better way to get the following: - link all tools and shared libraries to libLLVM if LLVM_LINK_LLVM_DYLIB is set - some way of explicitly *not* doing so for utilities and libLLVM itself Suggestions for improvement here are particularly welcome.

[cmake] fix a typo in llvm_config macro Summary: The macro parses out the USE_SHARED option out of the argument list, but then ignores it and accesses the variable with the same name instead. It seems the intention here was to check the argument value. Technically, this is NFC, because the only in-tree usage (add_llvm_executable) of USE_SHARED sets both the variable and the argument when calling llvm_config, but it makes the usage of this macro for out-of-tree users more sensible.

[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

[CMake][LLVM] Remove duplicated library mask. Broken clang linking against clangShared Summary: The `LLVM${c}Info` mask is listed twice in LLVM-Config.cmake. This results in the libraries such as LLVMARMInfo, LLVMAArch4Info, etc appearing twice in `extract_symbols.py` command line while building `clangShared`. `Extract_symbols.py` does not work well in such a case and completely ignores the symbols from the duplicated libraries. Thus, the LLVM(...)Info symbols do not get exported from `clangShared` and linking clang against it fails with unresolved dependencies. Seems to be a mere copy-paste mistake.

Break false dependencies on target libraries Summary: For the most part this consists of replacing ${LLVM_TARGETS_TO_BUILD} with some combination of AllTargets* so that they depend on specific components of a target backend rather than all of it. The overall effect of this is that, for example, tools like opt no longer falsely depend on the disassembler, while tools like llvm-ar no longer depend on the code generator. There's a couple quirks to point out here: * AllTargetsCodeGens is a bit more prevalent than expected. Tools like dsymutil seem to need it which I was surprised by. * llvm-xray linked to all the backends but doesn't seem to need any of them.

llvmbuildectomy - replace llvm-build by plain cmake No longer rely on an external tool to build the llvm component layout. Instead, leverage the existing `add_llvm_componentlibrary` cmake function and introduce `add_llvm_component_group` to accurately describe component behavior. These function store extra properties in the created targets. These properties are processed once all components are defined to resolve library dependencies and produce the header expected by llvm-config. Differential Revision: https://reviews.llvm.org/D90848

Re-commit: r366610 and r366612: Expand pseudo-components before embedding in llvm-config There were two main problems: * The 'nativecodegen' pseudo-component was unconditionally adding ${native_tgt}CodeGen even though it conditionally added ${native_tgt}Info and ${native_tgt}Desc. This has been fixed by making ${native_tgt}CodeGen conditional too * The 'all' pseudo-component was causing library names like LLVMLLVMDemangle as the expansion was to a library name and not a component. There doesn't seem to be a list of available components anywhere so this has been fixed by moving the expansion of 'all' back where it was before. This manifested in different ways on different builders but it was the same root cause llvm-svn: 366622

[cmake] Explicitly mark libraries defined in lib/ as "Component Libraries" Summary: Most libraries are defined in the lib/ directory but there are also a few libraries defined in tools/ e.g. libLLVM, libLTO. I'm defining "Component Libraries" as libraries defined in lib/ that may be included in libLLVM.so. Explicitly marking the libraries in lib/ as component libraries allows us to remove some fragile checks that attempt to differentiate between lib/ libraries and tools/ libraires: 1. In tools/llvm-shlib, because llvm_map_components_to_libnames(LIB_NAMES "all") returned a list of all libraries defined in the whole project, there was custom code needed to filter out libraries defined in tools/, none of which should be included in libLLVM.so. This code assumed that any library defined as static was from lib/ and everything else should be excluded. With this change, llvm_map_components_to_libnames(LIB_NAMES, "all") only returns libraries that have been added to the LLVM_COMPONENT_LIBS global cmake property, so this custom filtering logic can be removed. Doing this also fixes the build with BUILD_SHARED_LIBS=ON and LLVM_BUILD_LLVM_DYLIB=ON. 2. There was some code in llvm_add_library that assumed that libraries defined in lib/ would not have LLVM_LINK_COMPONENTS or ARG_LINK_COMPONENTS set. This is only true because libraries defined lib lib/ use LLVMBuild.txt and don't set these values. This code has been fixed now to check if the library has been explicitly marked as a component library, which should now make it easier to remove LLVMBuild at some point in the future. I have tested this patch on Windows, MacOS and Linux with release builds and the following combinations of CMake options: - "" (No options) - -DLLVM_BUILD_LLVM_DYLIB=ON - -DLLVM_LINK_LLVM_DYLIB=ON - -DBUILD_SHARED_LIBS=ON - -DBUILD_SHARED_LIBS=ON -DLLVM_BUILD_LLVM_DYLIB=ON - -DBUILD_SHARED_LIBS=ON -DLLVM_LINK_LLVM_DYLIB=ON Reviewers: beanz, smeenai, compnerd, phosek Reviewed By: beanz Subscribers: wuzish, jholewinski, arsenm, dschuff, jyknight, dylanmckay, sdardis, nemanjai, jvesely, nhaehnle, mgorny, mehdi_amini, sbc100, jgravelle-google, hiraditya, aheejin, fedor.sergeev, asb, rbar, johnrusso, simoncook, apazos, sabuasal, niosHD, jrtc27, MaskRay, zzheng, edward-jones, atanasyan, steven_wu, rogfer01, MartinMosbeck, brucehoult, the_o, dexonsmith, PkmX, jocewei, jsji, dang, Jim, lenary, s.egerton, pzheng, sameer.abuasal, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D70179

Teach LLVM-Config to use logical target names (2/2) The module still needs to collect the list of all available libraries in order to satisfy the 'all' component. Provide this in the package configuration file, 'LLVMConfig.cmake', as a LLVM_AVAILABLE_LIBS variable. (A variable is scoped better than a global property.) Since this won't be set for our own build, fall back to looking up the LLVM_LIBS property to get the value when it is not set. Contributed by Brad King. llvm-svn: 201853
