This article examines the execution speed of C++ compilers. There are two tests that are exclusively or primarily C only--Dhrystone and zlib. There are seven C++ tests: auto_buffer, fixed_array, int2string, multi_array, pod_vector, string tokenization (Boost) and string tokenization (STLSoft...
Choosing a compiler optimization level is crucial for controlling the trade-off between performance and debuggability. The Intel compilers default to an optimization level of -O2, which contrasts with most other compilers, such as GCC or Clang that default to -O0. Moreover, users do not expect...
Compiler optimization of C++ virtual function calls These optimizations were implemented in IBM's compiler, the C Set ++ for AIX/6000, and evaluated on a set of C++ standard benchmarks. We received encouragi... S Porat,D Bernstein,Y Fedorov,... 被引量: 0发表: 1996年 ...
the C++ compiler team went to great lengths to make sure that all of the expertise gained from years of optimizing native code was applied to managed code optimization. C++ gives you the flexibility to do fine tuning such as high-performance marshaling that is not possible with other languages...
On the contrary, it is important to remember that compilers are capable of performing transformations on the code in order to improve performance, but they aren’t capable of thinking.Compiler optimizationssave the developer from worrying about small inefficiencies, such as whether a multiplication ca...
Using the “Profile Guided Optimization” context menu, I will instrument the PrimeCalculator project, then the PrimeNumbers project, and choose “Run Instrumented/Optimized Build” to collect a new training run. I input 10K again as the limit, and when it finished use the “Profile Gu...
Compiler optimization for configurable accelerators ROCCC (Riverside Optimizing Configurable Computing Compiler) is an optimizing C to HDL compiler targeting FPGA and CSOC (Configurable System On a Chip) architectures. ROCCC system is built on the SUIF-MACHSUIF compiler infrastructure. Ou... B ...

However at level -O3, a number of additional optimization techniques are enabled which may produce higher performance code - but which are likely to also increase the code size. Note: The LPCXpresso IDE Version 7 ships with an updated version of the GNU C Compiler 4.8.2 supporting a new op...
