Then you can use clang++ -march=native -std=c++20 --precompile -c lib.cppm -o lib.pcm to convert the cppm into pcm. After that use clang++ -march=native -std=c++20 -c lib.pcm to generate .obj file ...
How fast? Faster than your compiler can do it! Compilers cleverly replace divisions by multiplications and shifts, if the divisor is known at compile time. In a hashing benchmark, our simple C code ...
