Although C and C++ compilers generally produce very compact object code, many performance
improvements are possible by careful source code optimization. Most such optimizations result from
taking advantage of the underlying mechanisms used by C and C++ compilers to translate source
code into sequences of AMD64 instructions. This chapter includes guidelines for writing C and C++
source code that result in the most efficiently optimized AMD64 code.
