Title
C++ Saturation Arithmetic
Abstract
Many real world problems require the use of “saturation arithmetic” to properly code the solution. This has traditionally been problematic as in C++ the flags register is not directly
accessible. C++ 26 supports saturation arithmetic via the standard library and this feature is available NOW in several compilers.
We’ll start with a definition of what “saturation arithmetic” is, then we’ll look at the efficiency of the code produced for the X86-64 and AARCH64 instruction sets for the GCC and Clang compilers.
