Abstract:
Multi-precision integer arithmetics is widely used, among other things in public-key cryptography and when computing many digits of transcendental numbers. The present paper discusses multi-precision addition and multiplication: architectural support and its use in hand-written assembly language, libraries that use such assembly-language code, and programming language support and how close the code generated by Clang and GCC is to the hand-written assembly language.
