This has a few advantages * Less C++ code (about 300 lines less). * Less machine code (about 14 KB of text on a linux x86_64 build). * It is more debugger friendly. Just set a breakpoint on the exit function and you get the complete lld stack trace of when the error was found. * It is a more robust API. The errors are handled early and we don't get a std::error_code hot potato being passed around. * In most cases the error function in a better position to print diagnostics (it has more context). llvm-svn: 244215
