CLANG38 build fail after CC_FLAG is added in the link rule. This failure is because the CLANG38 enable the LTO through LLVMgold.so linker plugin, but the LLVMgold.so plugin cannot accept the clang -Oz CC flag as build option. After CC_FLAG is added in the link rule, the LLVMgold.so plugin reports linking error. LLVMgold.so only accept -O0 ~ -O3, and you can see it in the LLVM gold plugin source code in below: http://llvm.org/svn/llvm-project/llvm/tags/RELEASE_380/final/tools/gold/ gold-plugin.cpp line173: if (opt[1] < '0' || opt[1] > '3') message(LDPL_FATAL, "Optimization level must be between 0 and 3"); Add -O3 in the *_CLANG38_*_DLINK2_FLAGS to override the -Oz flag in *_CLANG38_*_CC_FLAGS to pass LLVMgold.so linking.
