Thanks! Question about the final link step: Do I provide all the object files to the link step, i.e. something like: clang++ -o thinlto main-native.o lib/lib-native.o src/lib-native.o Do I need to provide --start-lib markers on that final link step as well?

I'm trying to run distributed ThinLTO without thin archives. When I do, I get an error in the optimizer when clang tries to open a nonexistent file: clang++ -flto=thin -Xclang -fno-lto-unit -O3 -c main.cpp -o main.o clang++ -flto=thin -Xclang -fno-lto-unit -O3 -c lib/lib.cpp -o lib/lib.o clang++ -flto=thin -Xclang -fno-lto-unit -O3 -c src/lib.cpp -o src/lib.o llvm-ar -format gnu qcs lib.a
