By 2011, Clang seemed to retain this advantage in compiler performance. [27] [28] As of mid-2014, Clang still consistently compiles faster than GCC in a mixed compile time and program performance benchmark. [29] However, by 2019, Clang is significantly slower at compiling the Linux Kernel than GCC while remaining slightly faster at compiling ...
Arm MAP, a performance profiler supporting Linux platforms. AppDynamics, an application performance management solution [buzzword] for C/C++ applications via SDK. AQtime Pro, a performance profiler and memory allocation debugger that can be integrated into Microsoft Visual Studio, and Embarcadero RAD Studio, or can run as a stand-alone application.
Microsoft Visual C++ (MSVC) is a compiler for the C, C++, C++/CLI and C++/CX programming languages by Microsoft. MSVC is proprietary software ; it was originally a standalone product but later became a part of Visual Studio and made available in both trialware and freeware forms.
Whether particular optimizations can and should be applied may depend on the characteristics of the target machine. Some compilers such as GCC and Clang parameterize machine-dependent factors so that they can be used to optimize for different machines. [7] Target CPU architecture. Number of registers: Registers can be used to optimize for ...

Klocwork: 2023-04-04 (2023.1) No; proprietary — C, C++, C# Java JavaScript — Python Kotlin
Whole program optimization (WPO) is the compiler optimization of a program using information about all the modules in the program. Normally, optimizations are performed on a per module, "compiland", basis; but this approach, while easier to write and test and less demanding of resources during the compilation itself, does not allow certainty about the safety of a number of optimizations such ...
The MSVC form of an embedded domain-specific language provides ease of writing, but it requires the compiler itself to know about opcode names and their clobbering properties, demanding extra attention in maintenance and porting. [7] It is still possible to check GCC-style assembly for clobber mistakes with knowledge of the instruction set. [8]
In computer programming, profile-guided optimization (PGO, sometimes pronounced as pogo [1]), also known as profile-directed feedback (PDF) [2] or feedback-directed optimization (FDO), [3] is the compiler optimization technique of using prior analyses of software artifacts or behaviors ("profiling") to improve the expected runtime performance of the program.
