Hi. I'm using LLVM 5.0.1 on macOS 10.12. I have a very simple program (program.c): int main() {} When attempting to compile with LLD, I get this output: $ clang -fuse-ld=lld program.c /opt/llvm/5.0.1/bin/ld.lld: error: unknown argument: -no_deduplicate /opt/llvm/5.0.1/bin/ld.lld: error: unknown argument: -dynamic /opt/llvm/5.0.1/bin/ld.lld: error: unknown argument: -arch /opt/llvm/5.0.1/bin/ld.lld: error: unknown emulation: acosx_version_min /opt/llvm/5.0.1/bin/ld.lld: error: unable to find library -lto_library /opt/llvm/5.0.1/bin/ld.lld: er...

This is usually a problem that is not using llvm-ar. I cannot reproduce this problem with either llvm 10.0 or TOT version. Which linker version are you using? You can also try pass "-Wl,-debug_snapshot" to the command where the error produces and then locate the "*.ld-snapshot" in /tmp directory and attach that as a reproducer.
