A shared library (unlike a .a), has its dependencies recorded in the library and we can pass PRIVATE to target_link_libraries. This patch then removes some bogus dependencies when using BUILD_SHARED_LIBS=ON. For example, we go from build lib/CodeGen/CMakeFiles/LLVMCodeGen.dir/AggressiveAntiDepBreaker.cpp.o: CXX_COMPILER /home/espindola/llvm/llvm/lib/CodeGen/AggressiveAntiDepBreaker.cpp || include/llvm/IR/intrinsics_gen lib/libLLVMSupport.so lib/libLLVMCore.so lib/libLLVMBitReader.so lib/libLLVMTransformUtils.so lib/libLLVMInstCombine.so lib/libLLVMScalarOpts.so lib/libLLVMipa.so lib/libLLVMAnalysis.so lib/libLLVMMCParser.so lib/libLLVMMC.so lib/libLLVMObject.so lib/libLLVMTarget.so lib/libLLVMProfileData.so to build lib/CodeGen/CMakeFiles/LLVMCodeGen.dir/AggressiveAntiDepBreaker.cpp.o: CXX_COMPILER /home/espindola/llvm/llvm/lib/CodeGen/AggressiveAntiDepBreaker.cpp || include/llvm/IR/intrinsics_gen lib/libLLVMSupport.so lib/libLLVMCore.so lib/libLLVMTransformUtils.so lib/libLLVMScalarOpts.so lib/libLLVMAnalysis.so lib/libLLVMMC.so lib/libLLVMTarget.so In fact, build.ninja goes from 5231028 bytes to 4896759 bytes. With this, old verisons of bfd ld (2.24 is OK, 2.23 warns) will print a bogus warning when building with BUILD_SHARED_LIBS. llvm-svn: 221530 |
