Compiler Features topics
Provides an overview of ARM-specific features of the compiler.
Compiler intrinsics are functions provided by the compiler. They enable you to easily incorporate domain-specific operations in C and C++ source code without resorting to complex implementations in assembly language.
NEON intrinsics provided by the compiler
As an alternative to automatic compiler vectorization, NEON intrinsics provide an intermediate step between a vectorizing compiler and writing assembly language for SIMD code generation.
Performance issues with Precompiled Header (PCH) files
Typically, the overhead of creating and reading a PCH file is small, even for reasonably large header files. If the PCH file is used, there is typically a significant decrease in compilation time. However, PCH files can range in size from about 250KB to several megabytes or more, so you might not want to create many PCH files.
