This is wonderful. By the way what does it mean when people say something is getting very popular? I am still sticking with C# for now as "it can do" what I am interested in!!!!!!! |

Stop posting off-topic-postings here and consult a psychiatrist. |

OK, I take the word. It's just g++ implementaion's favor of current release |

I have not seen this as compiler optimization so far. It is often difficult to construct test examples here, and to know which optimisations really help - sometimes optimisations that increase code size can give faster results by fine-tuning the different function versions, sometimes it can be slower due to cache effects, branch buffers, etc. So getting the very best results can be a lot of effort with testing, profiling, playing with compiler options, etc. And often it will only give the best results on one particular system - a slightly different cpu in the same family may need different choices. However, modern compilers can have a lot of techniques that can help here. For code de-duplication, this can be done by the compiler at the level of internal code trees (long before generating assembly). It can also be done at link time when the linker sees the same assembly for different functions. And compilers /do/ have partial inlining and cloning. They can clone functions and then make copies which depend on constant propagation - it is particularly easy to see how this can work when a function takes a "bool" parameter. Two versions - one for a "true" parameter, one for a "false" parameter, along with a wrapper function for an unknown value, might end up smaller and faster than a single large function. There are all sorts of fun optimisations to read about for compilers, such as: <https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html> Some optimisations take a great deal of compilation time and memory, however - there is no way to get everything that you might imagine. The compiler gets its best chances with link-time optimisation. But part of the fun of that when testing and investigating this stuff, is that changes to one part of the code can affect the final code generation in entirely different parts of the system. |
