Summary: For builds with LLVM_BUILD_LLVM_DYLIB=ON and BUILD_SHARED_LIBS=OFF this change makes all symbols in the target specific libraries hidden by default. A new macro called LLVM_EXTERNAL_VISIBILITY has been added to mark symbols in these libraries public, which is mainly needed for the definitions of the LLVMInitialize* functions. This patch reduces the number of public symbols in libLLVM.so by about 25%. This should improve load times for the dynamic library and also make abi checker tools, like abidiff require less memory when analyzing libLLVM.so One side-effect of this change is that for builds with LLVM_BUILD_LLVM_DYLIB=ON and LLVM_LINK_LLVM_DYLIB=ON some unittests that access symbols that are no longer public will need to be statically linked. Before and after public symbol counts (using gcc 8.2.1, ld.bfd 2.31.1): nm before/libLLVM-9svn.so | grep ' [A-Zuvw] ' | wc -l 36221 nm after/libLLVM-9svn.so | grep ' [A-Zuvw] ' | wc -l 26278 Reviewers: chandlerc, beanz, mgorny, rnk, hans Reviewed By: rnk, hans Subscribers: merge_guards_bot, luismarques, smeenai, ldionne, lenary, s.egerton, pzheng, sameer.abuasal, MaskRay, wuzish, echristo, Jim, hiraditya, michaelplatings, chapuni, jholewinski, arsenm, dschuff, jyknight, dylanmckay, sdardis, nemanjai, jvesely, javed.absar, sbc100, jgravelle-google, aheejin, kbarton, fedor.sergeev, asb, rbar, johnrusso, simoncook, apazos, sabuasal, niosHD, jrtc27, zzheng, edward-jones, mgrang, atanasyan, rogfer01, MartinMosbeck, brucehoult, the_o, PkmX, jocewei, kristina, jsji, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D54439
