Arch: Architecture Dependent

Overview

The ARCH library is a repository for all architecture-dependent code. It isolates all platform dependencies (and confusing #ifdefs) into one small library and also serves as a common area for documentation of these multi-platform issues.

The high-level grouping of the classes/functions is:

• Bits
• Multithreading
• Math
• Strings
• System Functions
• Memory Management
• Diagnostics
• Symbol Visibility

Symbols for use within libarch:

For OS:

• ARCH_OS_LINUX
• ARCH_OS_DARWIN
• ARCH_OS_WINDOWS

For processor:

• ARCH_CPU_INTEL
• ARCH_CPU_ARM

For bits:

• ARCH_BITS_64

For compiler:

• ARCH_COMPILER_CLANG
  • ARCH_COMPILER_CLANG_MAJOR
  • ARCH_COMPILER_CLANG_MINOR
  • ARCH_COMPILER_CLANG_PATCHLEVEL
• ARCH_COMPILER_GCC
  • ARCH_COMPILER_GCC_MAJOR
  • ARCH_COMPILER_GCC_MINOR
  • ARCH_COMPILER_GCC_PATCHLEVEL
• ARCH_COMPILER_MSVC
