The builtins library of compiler-rt is a performance HOG^WKILLER
...de an __asm block,
and add a function definition with __declspec(naked)
But then someone will have to find new filenames; I'd prefer to
leave them as *.ASM, so they can be added to YOUR source tree
without clobbering existing files.
The same holds for __alldiv, __alldvrm, __allrem, __aulldiv,
__aulldvrm and __aullrem, plus __allmul, __allshl, _allshr and
__aullshr.
If you name a reviewer I'll send them to llvm-commits!

Hi @ll,
LLVM-7.0.0-win32.exe contains and installs
lib\clang\7.0.0\lib\windows\clang_rt.builtins-i386.lib
The implementation of (at least) the multiplication and division
routines __[u]{div,mod,divmod,mul}[sdt]i[34] shipped with this
libraries SUCKS: they are factors SLOWER than even Microsoft's
NOTORIOUS POOR implementation of 64-bit division shipped with
MSVC and Windows!
The reasons: 1.
