[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 2019-11-14 06:39:58 +01:00			`add_llvm_component_library(LLVMOption`

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.
