Get a handle on optimizing floating-point code using the Microsoft Visual C++ ( version 8.0) method of managing floating-point semantics. In this article we will explore optimization techniques for C and C++ code developed for Realtime Systems. Discusses ways in which the Microsoft® Visual C++® compiler can optimize source code for speed and size and tells why code size matters. Any hints on how to prevent g++ from optimizing away my variables? The complete expression is too complicated even for clang. The C++ Standard Template Library (STL) provides the template function sort that implements a comparison sort algorithm. / Od disables optimization, speeding compilation and simplifying debugging. /O2 optimizes code for maximum speed. /Ob controls inline function expansion. Select the Configuration Properties, C/C++ folder. Early sections of the book address the advantages of optimizing C++, which the author considers something of a lost art. Even with g++ -O0 (yes, -O0 !), this happens. Reduced to mere minutes when fully optimized by the z/OS XL C/C++ compiler. If you can observe any different the the compiler is not allowed to remove the object. The "Empty Member" C++ Optimization. Generate enhanced debugging information for optimized code in non-debug builds.
