3.3.2 Optimization Considerations When Mixing C/C++ and Assembly 59. Unconstrained L-BFGS and CG optimizers. Improve the performance of your C++ programs to meet customer requirements for responsiveness and throughput. In this article we will explore optimization techniques for C and C++ code developed for Realtime Systems. When compared to C, C++ has some features that worsen efficiency if used inappropriately. The "Empty Member" C++ Optimization. Any hints on how to prevent g++ from optimizing away my variables? Anyway my question is more general: How do I start optimizing algorithms/loops/ for_each/etc. The libc++ basic_string is designed to have a sizeof 3 words on all architectures, where sizeof(word) == sizeof(void*) . 3.4 Use Caution With asm Statements in Optimized Code . GCC can use that data to optimize conditionals to perform as quickly as possible in the expected case, with slightly slower execution in the unexpected case. C++ run-time support routines obviously have a significant cost, because otherwise such behavior would have be inlined. Languages supported: C++, C#, VBA, Pascal.
