How is the cpp runtime compiled into the final executable? Compiling with -Xverbose-phases=ObjectFiles,Linker I can see that
• compiler produces a *.bc file which I presume is LLVM bitcode
• clang++ is invoked to compile into object file *.o
• clang invoked for linking and produces the executable
What I am missing is at which point and how is the K/N runtime injected?
