MSVC
Microsoft's C/C++ compiler, integrated into Visual Studio. It implements the __declspec family of extensions and some C11/C17 features, while largely not supporting GCC-family extensions.
Timeline (last 90 days)
Compiler built-ins such as GCC/Clang's __builtin_trap() and MSVC's __debugbreak() usually map directly to specific CPU instructions (such as x86's int3 or ud2), with extremely low performance overhead, but they depend on the compiler implementation, and cross-platform porting requires conditional compilation.
MSVC implements the __declspec family of extensions and some C11/C17 features, but largely does not support GCC-family extensions.
C++ still lacks a standardized ABI; binary code generated by different compilers (GCC, MSVC, Clang) may be mutually incompatible.
Modern compilers and high-performance libraries convert division by a constant into multiplication by a magic constant followed by a right shift—that is, for division by constant d, a large integer M and shift amount s are found such that ⌊n/d⌋ = ⌊n×M / 2^s⌋.
