Any > help appreciated. :-) (Also noted in bugzilla comment #13:) The following 2 link commands, producing and using an vastly-smaller lib/libLLVM-6.0.so reproduce the messages: "/usr/bin/powerpc64-unknown-freebsd13.0-ld" \ "-Bshareable" \ "-o" "lib/libLLVM-6.0.so" \ "/usr/lib/crtbeginS.o" \ "--version-script" = "/wrkdirs/usr/ports/devel/llvm60/work/.build/./lib/tools/llvm-shlib/simple= _version_script.map" \ "--whole-archive" \ "lib/libLLVMCore.a" \ "--no-whole-archive" \ "-lm" /usr/bin/powerpc64-unknown-freebsd13.0-ld \ "-Bshareable" \ "-o" "lib/libLTO.so.6.0.1" \ "lib/libLLVM-6.0.so" It looks like lib/libLLVMCore.a would be next for making it smaller. =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
